Conor McCabe sits down with CLEAR Conversations host, Tracy Sellers. At the CLEAR Center at UC Davis, researchers spend their days asking a big question with global stakes: how can we raise livestock in ways that are more climate-friendly? For PhD student Conor McCabe, now approaching the end of his fifth year in the Mitloehner Lab, that question has fueled not just one research project—but nearly an entire year of long days, early mornings, and a sprawling scientific effort that spans animals, microbes, emissions, and the future of food systems.
McCabe didn’t start out as a dairy kid. He grew up on a small farm in Oregon—“pretty much an Old McDonald’s farm,” he jokes—with pigs, cattle, pumpkins, and Christmas trees. His mother once served as a dairy princess, but dairy cattle weren’t part of Connor’s life until college. After studying animal science across Cornell, Purdue, and now UC Davis, he’s seen “different pockets of cows across the country,” as he puts it. But it wasn’t until arriving at Davis that he found the right intersection of ruminant biology and real-world impact.

00:00:00:00 - 00:00:00:11
Because at the
00:00:00:11 - 00:00:01:07
end of the day,
00:00:01:07 - 00:00:02:06
what we're
00:00:02:06 - 00:00:02:18
thinking about
00:00:02:18 - 00:00:03:19
how can we
00:00:03:19 - 00:00:04:22
improve nutrition,
00:00:04:22 - 00:00:06:07
how can we reduce
00:00:06:07 - 00:00:07:02
environmental impacts,
00:00:07:02 - 00:00:08:12
and how can we help with
00:00:08:12 - 00:00:09:09
the billions of people
00:00:09:09 - 00:00:10:12
that are involved
00:00:10:12 - 00:00:12:01
in livestock systems.
00:00:12:01 - 00:00:12:12
Think about
00:00:12:12 - 00:00:13:08
how do we create more
00:00:13:08 - 00:00:14:07
sustainable food systems,
00:00:14:07 - 00:00:14:23
at least for
00:00:14:23 - 00:00:15:23
for the rest of my
00:00:15:23 - 00:00:23:10
my career here.
00:00:23:12 - 00:00:24:03
Welcome to
00:00:24:03 - 00:00:25:14
Clear Conversations.
00:00:25:14 - 00:00:25:20
You know,
00:00:25:20 - 00:00:26:11
the clear center.
00:00:26:11 - 00:00:27:03
Our researchers
00:00:27:03 - 00:00:27:23
are testing ways
00:00:27:23 - 00:00:28:19
to make livestock
00:00:28:19 - 00:00:30:01
more climate friendly.
00:00:30:01 - 00:00:30:10
And today,
00:00:30:10 - 00:00:31:02
we're going to be talking
00:00:31:02 - 00:00:31:08
to one of
00:00:31:08 - 00:00:32:08
those researchers.
00:00:32:08 - 00:00:32:21
His name is
00:00:32:21 - 00:00:33:13
Conor McCabe,
00:00:33:13 - 00:00:34:10
and he's a
00:00:34:10 - 00:00:35:06
PhD student in the
00:00:35:06 - 00:00:36:07
Mitloehner lab.
00:00:36:07 - 00:00:36:20
He is working
00:00:36:20 - 00:00:38:00
with feed additives
00:00:38:00 - 00:00:38:17
with dairy cows.
00:00:38:17 - 00:00:39:09
And he's going to tell us
00:00:39:09 - 00:00:39:20
a little bit
00:00:39:20 - 00:00:41:01
about his research today.
00:00:41:01 - 00:00:41:09
Conor,
00:00:41:09 - 00:00:42:07
thanks for joining us.
00:00:42:07 - 00:00:43:11
I'm so happy to be here
00:00:43:11 - 00:00:44:01
and looking
00:00:44:01 - 00:00:44:13
forward to it.
00:00:44:13 - 00:00:45:02
All right.
00:00:45:02 - 00:00:45:21
We are looking forward
00:00:45:21 - 00:00:46:13
to talking to you.
00:00:46:13 - 00:00:47:04
So first of all,
00:00:47:04 - 00:00:47:18
tell us a little bit
00:00:47:18 - 00:00:48:13
about yourself
00:00:48:13 - 00:00:49:06
and your background.
00:00:49:06 - 00:00:50:16
You've done a lot,
00:00:50:16 - 00:00:50:22
even
00:00:50:22 - 00:00:51:18
before you came to UC
00:00:51:18 - 00:00:52:13
Davis. You've done a lot.
00:00:52:13 - 00:00:53:04
So tell us a little bit
00:00:53:04 - 00:00:54:00
about that. Yeah.
00:00:54:00 - 00:00:55:07
So I'm currently
00:00:55:07 - 00:00:55:23
wrapping up
00:00:55:23 - 00:00:57:03
the fifth year of my,
00:00:57:03 - 00:00:58:20
my PhD here at Davis.
00:00:58:20 - 00:01:00:08
The last couple of months
00:01:00:08 - 00:01:01:02
of my time
00:01:01:02 - 00:01:02:09
is coming up here,
00:01:02:09 - 00:01:03:08
but I'm originally
00:01:03:08 - 00:01:04:04
from the West Coast,
00:01:04:04 - 00:01:05:14
originally from Oregon
00:01:05:14 - 00:01:06:11
as my hometown where
00:01:06:11 - 00:01:08:02
my family has a
00:01:08:02 - 00:01:10:05
small farm where we have,
00:01:10:05 - 00:01:11:11
pigs,
00:01:11:11 - 00:01:12:15
cattle, Christmas
00:01:12:15 - 00:01:14:10
trees, pumpkins,
00:01:14:12 - 00:01:15:03
all that order.
00:01:15:03 - 00:01:15:19
So a big
00:01:15:19 - 00:01:17:11
old McDonald farm,
00:01:17:11 - 00:01:18:11
and that got my interest
00:01:18:11 - 00:01:20:22
in animal science.
00:01:20:22 - 00:01:21:19
And then
00:01:21:19 - 00:01:22:18
I went to New York,
00:01:22:18 - 00:01:24:10
to Cornell for undergrad,
00:01:24:10 - 00:01:25:16
did a masters at Purdue,
00:01:25:16 - 00:01:26:05
and now
00:01:26:05 - 00:01:26:22
I've come here to UC
00:01:26:22 - 00:01:28:00
Davis.
00:01:28:00 - 00:01:28:12
There's cows
00:01:28:12 - 00:01:29:05
across the country.
00:01:29:05 - 00:01:29:19
So I've kind of seen
00:01:29:19 - 00:01:30:09
a little different
00:01:30:09 - 00:01:31:18
pockets of,
00:01:31:18 - 00:01:33:10
cows throughout my work.
00:01:33:10 - 00:01:34:06
My mom was a dairy
00:01:34:06 - 00:01:35:13
princess growing up,
00:01:35:13 - 00:01:36:15
but we had no,
00:01:36:15 - 00:01:37:12
no experience
00:01:37:12 - 00:01:38:10
or affiliation
00:01:38:10 - 00:01:39:11
with dairy cattle myself
00:01:39:11 - 00:01:39:22
because the cows
00:01:39:22 - 00:01:40:12
were sold off
00:01:40:12 - 00:01:42:07
before I was born.
00:01:42:07 - 00:01:43:05
But it came
00:01:43:05 - 00:01:43:21
on back to me,
00:01:43:21 - 00:01:44:08
and I've since
00:01:44:08 - 00:01:45:01
been involved
00:01:45:01 - 00:01:45:22
ever since here
00:01:45:22 - 00:01:46:08
with different
00:01:46:08 - 00:01:47:11
research projects
00:01:47:11 - 00:01:49:03
across different places
00:01:49:03 - 00:01:49:16
of the country.
00:01:49:16 - 00:01:50:19
And I knew all along
00:01:50:19 - 00:01:51:10
that I had an interest
00:01:51:10 - 00:01:51:21
in coming back
00:01:51:21 - 00:01:52:17
to the West Coast.
00:01:52:17 - 00:01:54:08
I had an interest in,
00:01:54:08 - 00:01:54:16
looking
00:01:54:16 - 00:01:55:02
at the
00:01:55:02 - 00:01:55:20
environmental
00:01:55:20 - 00:01:56:13
opportunities
00:01:56:13 - 00:01:58:02
in animal agriculture.
00:01:58:02 - 00:01:58:15
And UC Davis
00:01:58:15 - 00:01:59:09
was really the place
00:01:59:09 - 00:02:00:07
for that to be
00:02:00:07 - 00:02:01:04
and for me to come to.
00:02:01:04 - 00:02:02:10
So,
00:02:02:12 - 00:02:03:14
this lab and this
00:02:03:14 - 00:02:04:08
opportunity here
00:02:04:08 - 00:02:05:02
with Dr. Mitloehner
00:02:05:02 - 00:02:05:14
really checked
00:02:05:14 - 00:02:06:09
all those boxes
00:02:06:09 - 00:02:08:01
and then led into me
00:02:08:01 - 00:02:08:21
coming here to
00:02:08:21 - 00:02:10:07
to Davis five years ago.
00:02:10:07 - 00:02:11:02
Where were I
00:02:11:02 - 00:02:11:08
I know
00:02:11:08 - 00:02:11:20
I'm in
00:02:11:20 - 00:02:12:15
the final stages
00:02:12:15 - 00:02:13:19
right now, so why
00:02:13:19 - 00:02:14:10
why dairy cows
00:02:14:10 - 00:02:15:06
and why sustainability?
00:02:15:06 - 00:02:15:18
Why was that
00:02:15:18 - 00:02:16:12
interesting to you?
00:02:16:12 - 00:02:17:04
Why did you know
00:02:17:04 - 00:02:18:09
you wanted to do that?
00:02:18:09 - 00:02:18:17
Yeah.
00:02:18:17 - 00:02:20:21
So I think there's
00:02:20:21 - 00:02:21:09
I mean, it's
00:02:21:09 - 00:02:22:05
one of the hottest topics
00:02:22:05 - 00:02:24:19
for sure right now.
00:02:24:19 - 00:02:25:06
You know,
00:02:25:06 - 00:02:26:01
I had a lot of
00:02:26:01 - 00:02:26:22
opportunities with pigs,
00:02:26:22 - 00:02:27:05
and that's
00:02:27:05 - 00:02:27:23
actually my first
00:02:27:23 - 00:02:30:10
entryway to,
00:02:30:10 - 00:02:31:09
to livestock.
00:02:31:09 - 00:02:32:05
But then when I
00:02:32:05 - 00:02:33:12
went to undergrad,
00:02:33:12 - 00:02:34:19
the only opportunity
00:02:34:19 - 00:02:35:05
to get involved
00:02:35:05 - 00:02:35:13
in production
00:02:35:13 - 00:02:36:19
agriculture was
00:02:36:19 - 00:02:38:05
dairy cattle.
00:02:38:05 - 00:02:38:15
Because that's
00:02:38:15 - 00:02:40:22
what Cornell offered.
00:02:40:22 - 00:02:42:02
And, you know, at
00:02:42:02 - 00:02:42:10
first
00:02:42:10 - 00:02:43:12
I started learning more.
00:02:43:12 - 00:02:43:21
So I gained
00:02:43:21 - 00:02:44:12
a liking to it.
00:02:44:12 - 00:02:45:13
And then really
00:02:45:13 - 00:02:46:20
seeing opportunities
00:02:46:20 - 00:02:47:20
are open to you
00:02:47:20 - 00:02:48:13
through what
00:02:48:13 - 00:02:49:12
I had in undergrad,
00:02:49:12 - 00:02:50:04
from research,
00:02:50:04 - 00:02:51:18
from teaching, from,
00:02:51:18 - 00:02:52:21
on farm opportunities.
00:02:52:21 - 00:02:53:09
You know,
00:02:53:09 - 00:02:54:09
no dairy farm
00:02:54:09 - 00:02:55:20
is the same, you know,
00:02:55:20 - 00:02:57:04
in terms of management,
00:02:57:04 - 00:02:57:15
in terms
00:02:57:15 - 00:02:58:17
of different practices,
00:02:58:17 - 00:02:59:03
in terms
00:02:59:03 - 00:03:00:10
of what different
00:03:00:10 - 00:03:01:15
situations,
00:03:01:15 - 00:03:02:11
are spread out
00:03:02:11 - 00:03:03:20
and like the different
00:03:03:20 - 00:03:04:19
management strategies.
00:03:04:19 - 00:03:05:12
I felt like, wow,
00:03:05:12 - 00:03:06:05
this is really cool.
00:03:06:05 - 00:03:06:17
There's a lot of
00:03:06:17 - 00:03:08:14
opportunities here.
00:03:08:16 - 00:03:09:09
Plus, I
00:03:09:09 - 00:03:10:08
really enjoy butter,
00:03:10:08 - 00:03:11:04
ice cream, cheese,
00:03:11:04 - 00:03:12:08
like many of us do
00:03:12:08 - 00:03:13:06
other points
00:03:13:06 - 00:03:14:05
So it's been,
00:03:14:05 - 00:03:16:00
been a cool opportunity point
00:03:16:00 - 00:03:16:13
But I know a lot of
00:03:16:13 - 00:03:17:02
people are interested
00:03:17:02 - 00:03:17:19
about sustainability
00:03:17:19 - 00:03:18:06
and thinking about
00:03:18:06 - 00:03:19:09
what is
00:03:19:09 - 00:03:20:22
the role of dairy cattle
00:03:20:22 - 00:03:22:08
in livestock systems.
00:03:22:08 - 00:03:23:15
And, you know,
00:03:23:15 - 00:03:24:08
I have those
00:03:24:08 - 00:03:25:22
same questions, too,
00:03:25:22 - 00:03:26:15
coming up, in terms
00:03:26:15 - 00:03:28:09
of what our opportunities
00:03:28:09 - 00:03:29:20
here, where
00:03:29:20 - 00:03:31:00
where do cattle fit
00:03:31:00 - 00:03:32:13
to the climate systems
00:03:32:13 - 00:03:34:02
and what,
00:03:34:02 - 00:03:35:04
what role do they play
00:03:35:04 - 00:03:36:13
and thinking about
00:03:36:13 - 00:03:37:05
food systems
00:03:37:05 - 00:03:38:23
as a whole and so,
00:03:38:23 - 00:03:39:11
California,
00:03:39:11 - 00:03:39:21
of course,
00:03:39:21 - 00:03:41:22
has many different forces
00:03:41:22 - 00:03:43:16
that are all combined
00:03:43:16 - 00:03:45:02
in this nexus right here.
00:03:45:02 - 00:03:45:23
And so I wanted to,
00:03:45:23 - 00:03:46:23
to pursue
00:03:46:23 - 00:03:47:17
this pathway
00:03:47:17 - 00:03:48:12
and think about
00:03:48:12 - 00:03:48:20
what are
00:03:48:20 - 00:03:49:17
some real opportunities.
00:03:49:17 - 00:03:50:18
And this is
00:03:50:18 - 00:03:51:09
this field
00:03:51:09 - 00:03:52:15
is exponential growing.
00:03:52:15 - 00:03:53:07
And it's still going
00:03:53:07 - 00:03:53:21
to continue
00:03:53:21 - 00:03:55:00
that exponential
00:03:55:00 - 00:03:56:04
growth here going forward
00:03:56:04 - 00:03:57:05
in terms of
00:03:57:05 - 00:03:57:17
thinking about
00:03:57:17 - 00:03:58:10
how do we continue
00:03:58:10 - 00:03:59:16
to have animals
00:03:59:16 - 00:04:01:09
part of food system
00:04:01:09 - 00:04:02:22
sustainability solutions.
00:04:02:22 - 00:04:03:20
And speaking about that,
00:04:03:20 - 00:04:04:05
let's talk
00:04:04:05 - 00:04:05:11
about ruminant animals
00:04:05:11 - 00:04:06:10
and what makes them so
00:04:06:10 - 00:04:07:23
complex and unique.
00:04:07:23 - 00:04:09:02
And what is a ruminant animal
00:04:09:02 - 00:04:10:03
explain that to us
00:04:10:03 - 00:04:10:18
a little bit.
00:04:10:18 - 00:04:11:00
Yeah.
00:04:11:00 - 00:04:11:12
So ruminant
00:04:11:12 - 00:04:12:20
animals are animals
00:04:12:20 - 00:04:14:03
that have specific
00:04:14:03 - 00:04:15:20
four chambered stomachs.
00:04:15:20 - 00:04:16:17
So they've evolved
00:04:16:17 - 00:04:17:06
over thousands
00:04:17:06 - 00:04:18:19
of thousands of years.
00:04:18:19 - 00:04:19:07
And this isn't
00:04:19:07 - 00:04:20:09
not just include cattle
00:04:20:09 - 00:04:21:21
or goats or sheep
00:04:21:21 - 00:04:22:18
that we have, you know,
00:04:22:18 - 00:04:23:20
on, farms
00:04:23:20 - 00:04:24:13
here in California
00:04:24:13 - 00:04:25:20
across the US.
00:04:25:20 - 00:04:27:01
But this also includes
00:04:27:01 - 00:04:28:04
the deer,
00:04:28:04 - 00:04:29:03
the bison,
00:04:29:03 - 00:04:31:04
the wild animals, too.
00:04:31:04 - 00:04:31:13
In order
00:04:31:13 - 00:04:33:10
for them to predominantly,
00:04:33:10 - 00:04:34:12
consume their diets
00:04:34:12 - 00:04:35:09
that are high in fiber
00:04:35:09 - 00:04:36:12
and things that humans
00:04:36:12 - 00:04:38:01
can't consume.
00:04:38:01 - 00:04:38:18
They utilize
00:04:38:18 - 00:04:39:11
this different
00:04:39:11 - 00:04:40:06
chambered stomach
00:04:40:06 - 00:04:40:14
to help
00:04:40:14 - 00:04:41:12
break down the fiber,
00:04:41:12 - 00:04:42:00
thanks to the help
00:04:42:00 - 00:04:42:12
of microbes
00:04:42:12 - 00:04:44:00
present in the gut.
00:04:44:00 - 00:04:44:14
And so in order
00:04:44:14 - 00:04:45:14
for them to consume feed,
00:04:45:14 - 00:04:48:13
of course, they have to,
00:04:48:15 - 00:04:50:01
have microbes to aid in
00:04:50:01 - 00:04:50:23
that digestion
00:04:50:23 - 00:04:52:06
of what they consume.
00:04:52:06 - 00:04:52:20
But then there's
00:04:52:20 - 00:04:53:18
also a trade off
00:04:53:18 - 00:04:55:11
in byproduct that
00:04:55:11 - 00:04:58:09
that methane is produced,
00:04:58:09 - 00:05:00:08
as a result of that
00:05:00:08 - 00:05:01:18
fermentation break down
00:05:01:18 - 00:05:02:15
process in the gut.
00:05:02:15 - 00:05:04:04
So, thinking about
00:05:04:04 - 00:05:05:11
how can you still provide
00:05:05:11 - 00:05:05:22
for animals
00:05:05:22 - 00:05:06:11
and think about
00:05:06:11 - 00:05:06:19
what they
00:05:06:19 - 00:05:07:18
need
00:05:07:20 - 00:05:09:00
and how they've evolved,
00:05:09:00 - 00:05:10:18
while also limiting
00:05:10:18 - 00:05:11:08
methane emissions
00:05:11:08 - 00:05:12:07
at the same time
00:05:12:07 - 00:05:14:07
Is this counterbalance,
00:05:14:07 - 00:05:15:14
place that we
00:05:15:14 - 00:05:16:12
we think about
00:05:16:12 - 00:05:17:12
what are opportunities
00:05:17:12 - 00:05:19:02
to find solutions
00:05:19:02 - 00:05:19:21
that
00:05:19:21 - 00:05:21:09
maximize animal health
00:05:21:09 - 00:05:22:10
and what they've evolved,
00:05:22:10 - 00:05:23:11
to consume.
00:05:23:11 - 00:05:24:02
But also,
00:05:24:02 - 00:05:24:13
how can we
00:05:24:13 - 00:05:25:06
essentially limit
00:05:25:06 - 00:05:27:00
or reduce
00:05:27:00 - 00:05:28:04
those methane emissions
00:05:28:04 - 00:05:28:20
produced that way
00:05:28:20 - 00:05:29:17
as well?
00:05:29:17 - 00:05:30:08
And one of those
00:05:30:08 - 00:05:31:12
possible solutions
00:05:31:12 - 00:05:32:16
are feed additives
00:05:32:16 - 00:05:33:07
And that's what you're
00:05:33:07 - 00:05:33:18
working on.
00:05:33:18 - 00:05:34:17
Explain your research
00:05:34:17 - 00:05:35:15
a little bit to us.
00:05:35:15 - 00:05:36:20
Yeah, so feed additives.
00:05:36:20 - 00:05:37:08
You know, I love
00:05:37:08 - 00:05:39:09
to use the analogy
00:05:39:09 - 00:05:40:09
of how we
00:05:40:09 - 00:05:41:00
where we feed
00:05:41:00 - 00:05:41:08
animals
00:05:41:08 - 00:05:42:12
is basically a casserole.
00:05:42:12 - 00:05:43:00
So we take
00:05:43:00 - 00:05:43:19
everything together,
00:05:43:19 - 00:05:44:12
we take the haze,
00:05:44:12 - 00:05:45:18
we take the byproducts,
00:05:45:18 - 00:05:46:08
and we mix them
00:05:46:08 - 00:05:46:21
all together
00:05:46:21 - 00:05:47:15
so that, you know,
00:05:47:15 - 00:05:47:20
when you're
00:05:47:20 - 00:05:49:03
taking a scoop of
00:05:49:03 - 00:05:49:18
that casserole,
00:05:49:18 - 00:05:50:05
you're not just
00:05:50:05 - 00:05:51:09
getting the,
00:05:51:09 - 00:05:52:19
the pasta
00:05:52:19 - 00:05:53:07
the noodles
00:05:53:07 - 00:05:53:19
or the sauce.
00:05:53:19 - 00:05:54:11
You're getting everything
00:05:54:11 - 00:05:55:20
involved in that.
00:05:55:20 - 00:05:56:10
The additives, it's
00:05:56:10 - 00:05:56:19
just like
00:05:56:19 - 00:05:57:16
the small spices
00:05:57:16 - 00:05:58:04
that you add on
00:05:58:04 - 00:05:58:19
on top of it
00:05:58:19 - 00:05:59:04
before you
00:05:59:04 - 00:05:59:18
put it in the oven.
00:05:59:18 - 00:06:00:16
There.
00:06:00:16 - 00:06:01:00
So these are
00:06:01:00 - 00:06:02:14
small, components
00:06:02:14 - 00:06:03:07
that have the ability
00:06:03:07 - 00:06:04:18
to make a big impact
00:06:04:18 - 00:06:05:13
on emissions
00:06:05:13 - 00:06:06:17
because they can do
00:06:06:17 - 00:06:07:06
two things.
00:06:07:06 - 00:06:07:22
They can do one,
00:06:07:22 - 00:06:09:02
they can inhibit
00:06:09:02 - 00:06:10:00
the pathway
00:06:10:00 - 00:06:10:17
or the enzymes
00:06:10:17 - 00:06:11:08
that are responsible
00:06:11:08 - 00:06:12:18
for methane formation
00:06:12:18 - 00:06:13:15
or they can make it
00:06:13:15 - 00:06:14:16
less favorable to form
00:06:14:16 - 00:06:15:03
methane in the
00:06:15:03 - 00:06:16:08
first place.
00:06:16:08 - 00:06:17:05
Two classifications.
00:06:17:05 - 00:06:18:01
The first one there
00:06:18:01 - 00:06:18:15
that I talked about
00:06:18:15 - 00:06:19:09
be inhibitors,
00:06:19:09 - 00:06:20:03
the second one will be
00:06:20:03 - 00:06:21:10
rumen modifiers there
00:06:21:10 - 00:06:22:07
that in small amounts
00:06:22:07 - 00:06:23:16
can have impacts anywhere
00:06:23:16 - 00:06:24:15
from about 10
00:06:24:15 - 00:06:26:05
to 30% reductions.
00:06:26:05 - 00:06:28:02
Wow, wow.
00:06:28:02 - 00:06:28:22
So tell us a little bit
00:06:28:22 - 00:06:29:18
about the research study
00:06:29:18 - 00:06:30:07
that you've been
00:06:30:07 - 00:06:30:21
a part of here,
00:06:30:21 - 00:06:31:22
how big it is.
00:06:31:22 - 00:06:32:16
And just
00:06:32:16 - 00:06:33:06
I mean, just tell us
00:06:33:06 - 00:06:33:20
a little bit about it
00:06:33:20 - 00:06:34:15
because it is amazing.
00:06:34:15 - 00:06:34:22
Yeah.
00:06:34:22 - 00:06:35:22
So it's been going on
00:06:35:22 - 00:06:39:02
for almost
00:06:39:04 - 00:06:39:20
almost a year.
00:06:39:20 - 00:06:40:03
We're going to
00:06:40:03 - 00:06:40:14
approaching that
00:06:40:14 - 00:06:41:02
at this point
00:06:41:02 - 00:06:41:16
and still not
00:06:41:16 - 00:06:42:18
even halfway over.
00:06:42:18 - 00:06:43:18
So it is
00:06:43:18 - 00:06:45:14
it's a long haul.
00:06:45:14 - 00:06:46:16
Coming here.
00:06:46:16 - 00:06:47:13
at Davis,
00:06:47:13 - 00:06:48:01
we’re working with
00:06:48:01 - 00:06:49:18
the molecule,
00:06:49:18 - 00:06:51:14
3-Nitrooxypropanol
00:06:51:14 - 00:06:52:13
or how we're going to
00:06:52:13 - 00:06:53:07
to refer it on
00:06:53:07 - 00:06:53:19
out here,
00:06:53:19 - 00:06:54:20
just say 3-NOP
00:06:54:20 - 00:06:56:02
because that's,
00:06:56:02 - 00:06:56:18
a little bit easier
00:06:56:18 - 00:06:57:08
for on the
00:06:57:08 - 00:06:59:02
on the eyes and ears.
00:06:59:02 - 00:07:00:07
3-NOP is a product
00:07:00:07 - 00:07:00:21
that's coming
00:07:00:21 - 00:07:01:07
commercially
00:07:01:07 - 00:07:02:03
available here
00:07:02:03 - 00:07:02:22
in California, though
00:07:02:22 - 00:07:03:07
different
00:07:03:07 - 00:07:04:04
different companies
00:07:04:04 - 00:07:04:17
in many
00:07:04:17 - 00:07:05:07
different countries
00:07:05:07 - 00:07:05:18
around the world.
00:07:05:18 - 00:07:07:10
But it's been,
00:07:07:12 - 00:07:08:07
approved by different
00:07:08:07 - 00:07:09:15
regulatory groups.
00:07:09:15 - 00:07:10:18
And,
00:07:10:18 - 00:07:11:13
it has the opportunity
00:07:11:13 - 00:07:11:23
to reduce
00:07:11:23 - 00:07:12:16
methane emissions
00:07:12:16 - 00:07:13:00
by anywhere
00:07:13:00 - 00:07:14:07
from about 20 to 30%,
00:07:14:07 - 00:07:15:11
depending on the study,
00:07:15:11 - 00:07:16:08
depending on
00:07:16:08 - 00:07:16:23
what what
00:07:16:23 - 00:07:18:09
animals are fed.
00:07:18:09 - 00:07:18:22
Because of course
00:07:18:22 - 00:07:19:14
there's interactions,
00:07:19:14 - 00:07:20:02
of course, when
00:07:20:02 - 00:07:21:01
the animals eat
00:07:21:01 - 00:07:21:19
to how much methane
00:07:21:19 - 00:07:22:07
they produce
00:07:22:07 - 00:07:23:02
and how well this
00:07:23:02 - 00:07:24:18
3-NOP works.
00:07:24:18 - 00:07:25:01
Well,
00:07:25:01 - 00:07:25:21
our goal for this
00:07:25:21 - 00:07:28:09
project is is looking at
00:07:28:09 - 00:07:29:09
you know,
00:07:29:09 - 00:07:30:08
I talked about animals
00:07:30:08 - 00:07:30:20
evolving
00:07:30:20 - 00:07:31:19
for a ruminant stomach
00:07:31:19 - 00:07:34:06
over thousands of years.
00:07:34:06 - 00:07:36:05
But these,
00:07:36:05 - 00:07:37:08
digestive systems of cows
00:07:37:08 - 00:07:38:18
have never seen something
00:07:38:18 - 00:07:39:20
that would inhibit
00:07:39:20 - 00:07:41:05
methane production.
00:07:41:05 - 00:07:42:13
For this period of time.
00:07:42:13 - 00:07:43:15
So could
00:07:43:15 - 00:07:45:01
the microbes in the gut
00:07:45:01 - 00:07:46:18
essentially work around
00:07:46:18 - 00:07:49:03
these stressors?
00:07:49:03 - 00:07:49:18
Because that's essential.
00:07:49:18 - 00:07:50:04
what they are
00:07:50:04 - 00:07:52:05
They're disrupting what,
00:07:52:05 - 00:07:52:20
what would have
00:07:52:20 - 00:07:54:02
historically been a
00:07:54:02 - 00:07:54:19
natural part
00:07:54:19 - 00:07:56:09
of digestion there.
00:07:56:09 - 00:07:57:05
And so
00:07:57:05 - 00:07:57:22
we're looking
00:07:57:22 - 00:07:58:15
interested to see
00:07:58:15 - 00:07:59:11
are emission reductions
00:07:59:11 - 00:08:00:07
the same on day
00:08:00:07 - 00:08:01:20
one as they are on day
00:08:01:20 - 00:08:03:11
500 plus.
00:08:03:11 - 00:08:04:18
Is the real interest here
00:08:04:18 - 00:08:05:18
because there's
00:08:05:18 - 00:08:06:14
there's folks
00:08:06:14 - 00:08:07:09
in the dairy industry,
00:08:07:09 - 00:08:08:01
there's folks
00:08:08:01 - 00:08:09:14
who are milk buyers
00:08:09:14 - 00:08:10:00
and trying
00:08:10:00 - 00:08:11:19
to figure out their own,
00:08:11:19 - 00:08:13:03
solutions for their own
00:08:13:03 - 00:08:14:00
milk supply chain
00:08:14:00 - 00:08:15:19
and carbon associations
00:08:15:19 - 00:08:18:05
to figure out,
00:08:18:07 - 00:08:19:05
can we utilize
00:08:19:05 - 00:08:20:02
this feed additive
00:08:20:02 - 00:08:22:06
as a solution today,
00:08:22:06 - 00:08:25:00
next year, next decade?
00:08:25:00 - 00:08:25:20
As we think about
00:08:25:20 - 00:08:26:14
trying to
00:08:26:14 - 00:08:28:04
permanently reduce
00:08:28:04 - 00:08:29:10
methane emissions
00:08:29:10 - 00:08:30:05
long term here
00:08:30:05 - 00:08:30:22
in California.
00:08:30:22 - 00:08:31:19
Wow.
00:08:31:19 - 00:08:32:16
So how big is this?
00:08:32:16 - 00:08:32:21
I mean,
00:08:32:21 - 00:08:33:14
how many cows
00:08:33:14 - 00:08:34:11
can we talk about that?
00:08:34:11 - 00:08:34:20
Yeah.
00:08:34:20 - 00:08:35:14
And the scope
00:08:35:14 - 00:08:36:10
and size and scale.
00:08:36:10 - 00:08:38:02
So you know, right now
00:08:38:02 - 00:08:40:04
we currently have 66
00:08:40:04 - 00:08:41:18
cows on study.
00:08:41:18 - 00:08:42:10
When you look at the
00:08:42:10 - 00:08:43:14
UC Davis dairy,
00:08:43:14 - 00:08:44:19
that's about two thirds
00:08:44:19 - 00:08:45:06
the animals.
00:08:45:06 - 00:08:46:00
So
00:08:46:00 - 00:08:46:21
so we're basically feeding
00:08:46:21 - 00:08:48:10
the entire dairy of cows
00:08:48:10 - 00:08:49:08
every single
00:08:49:08 - 00:08:50:04
morning in the night,
00:08:50:04 - 00:08:51:09
which is a lot of work.
00:08:51:09 - 00:08:51:19
And there's a whole
00:08:51:19 - 00:08:52:04
bunch of people
00:08:52:04 - 00:08:52:15
that are involved
00:08:52:15 - 00:08:53:10
in making this happen
00:08:53:10 - 00:08:54:22
from other grad students,
00:08:54:22 - 00:08:55:18
junior specialists,
00:08:55:18 - 00:08:57:23
postdocs, undergrads,
00:08:57:23 - 00:08:58:14
who are all putting
00:08:58:14 - 00:08:59:09
in a lot of hours
00:08:59:09 - 00:09:00:01
and making
00:09:00:01 - 00:09:01:03
this all happen every
00:09:01:03 - 00:09:02:23
single day of the year.
00:09:03:01 - 00:09:03:21
And, you know,
00:09:03:21 - 00:09:05:12
it's going to be
00:09:05:12 - 00:09:06:15
have a big celebration
00:09:06:15 - 00:09:07:03
for sure.
00:09:07:03 - 00:09:07:21
When it's all
00:09:07:21 - 00:09:09:08
going to be done
00:09:09:08 - 00:09:10:02
when they
00:09:10:02 - 00:09:10:16
when we finally
00:09:10:16 - 00:09:11:06
figure out that,
00:09:11:06 - 00:09:11:17
that final,
00:09:11:17 - 00:09:12:10
they’d have to pencil
00:09:12:10 - 00:09:14:16
that in and figure out,
00:09:14:16 - 00:09:15:08
where, what
00:09:15:08 - 00:09:16:00
what celebration
00:09:16:00 - 00:09:16:18
we're going to do then.
00:09:16:18 - 00:09:18:07
But, yeah,
00:09:18:07 - 00:09:19:01
it's a whole lot
00:09:19:01 - 00:09:19:21
of combinations.
00:09:19:21 - 00:09:21:02
And they’re so different
00:09:21:02 - 00:09:21:20
many offsets
00:09:21:20 - 00:09:22:13
that we're looking at.
00:09:22:13 - 00:09:24:13
How does this impact,
00:09:24:13 - 00:09:25:05
the whole animal.
00:09:25:05 - 00:09:25:20
So how does it
00:09:25:20 - 00:09:27:10
impacts, emissions?
00:09:27:10 - 00:09:28:11
How does it impact animal
00:09:28:11 - 00:09:28:21
health,
00:09:28:21 - 00:09:30:23
animal production?
00:09:30:23 - 00:09:32:06
The microbiome
00:09:32:06 - 00:09:33:20
are also other,
00:09:33:20 - 00:09:34:04
pieces
00:09:34:04 - 00:09:35:06
that we're interested in.
00:09:35:06 - 00:09:35:23
So there's,
00:09:35:23 - 00:09:36:11
there's many
00:09:36:11 - 00:09:38:10
different components.
00:09:38:10 - 00:09:39:17
Because who knows
00:09:39:17 - 00:09:40:15
if and when this,
00:09:40:15 - 00:09:41:00
this study
00:09:41:00 - 00:09:41:16
will be replicated
00:09:41:16 - 00:09:43:08
because, you know,
00:09:43:08 - 00:09:44:01
we may have,
00:09:44:01 - 00:09:45:00
have done all this work
00:09:45:00 - 00:09:45:12
and been like,
00:09:45:12 - 00:09:46:05
that's a lot of work.
00:09:46:05 - 00:09:46:20
And maybe
00:09:46:20 - 00:09:47:18
no one else for,
00:09:47:18 - 00:09:48:09
for any other piece
00:09:48:09 - 00:09:49:03
is going to want
00:09:49:03 - 00:09:49:20
to pursue that.
00:09:49:20 - 00:09:51:04
So it's
00:09:51:04 - 00:09:52:05
certainly exciting piece
00:09:52:05 - 00:09:53:09
to be part of helping
00:09:53:09 - 00:09:54:21
set up and play a role
00:09:54:21 - 00:09:56:04
in taking part
00:09:56:04 - 00:09:58:03
in this at this time.
00:09:58:05 - 00:10:00:17
And excited to see,
00:10:00:17 - 00:10:01:16
when those results
00:10:01:16 - 00:10:02:11
come out, you know, no
00:10:02:11 - 00:10:02:21
guarantee
00:10:02:21 - 00:10:03:14
when that's going to be,
00:10:03:14 - 00:10:05:13
but it's going to be
00:10:05:13 - 00:10:06:00
we're going to say
00:10:06:00 - 00:10:07:10
at least a few years
00:10:07:10 - 00:10:07:22
from now
00:10:07:22 - 00:10:08:14
until till
00:10:08:14 - 00:10:09:07
those conclusions
00:10:09:07 - 00:10:10:16
are brought together.
00:10:10:16 - 00:10:11:00
And you're
00:10:11:00 - 00:10:11:22
just logistically,
00:10:11:22 - 00:10:12:18
I mean, how
00:10:12:18 - 00:10:13:13
how long does it take
00:10:13:13 - 00:10:14:09
to get the cattle
00:10:14:09 - 00:10:15:09
kind of acclimated
00:10:15:09 - 00:10:16:12
to the feed additive?
00:10:16:12 - 00:10:17:04
How do you give them
00:10:17:04 - 00:10:17:21
the feed additive?
00:10:17:21 - 00:10:18:10
Tell us a little bit
00:10:18:10 - 00:10:19:21
about that process. Yes.
00:10:19:21 - 00:10:21:07
So our feed additive
00:10:21:07 - 00:10:22:23
that we're utilizing,
00:10:22:23 - 00:10:24:21
we are
00:10:24:21 - 00:10:25:16
it is a very
00:10:25:16 - 00:10:26:04
small amount,
00:10:26:04 - 00:10:26:11
you know,
00:10:26:11 - 00:10:27:10
I could hold in my hand
00:10:27:10 - 00:10:28:03
right here
00:10:28:03 - 00:10:29:07
how much each animal
00:10:29:07 - 00:10:30:16
is consuming per day.
00:10:30:16 - 00:10:32:06
So we think
00:10:32:06 - 00:10:33:00
about an animal
00:10:33:00 - 00:10:33:14
and I want to just
00:10:33:14 - 00:10:34:08
point out that
00:10:34:08 - 00:10:36:02
an average for,
00:10:36:02 - 00:10:36:15
for cows,
00:10:36:15 - 00:10:37:03
they're consuming
00:10:37:03 - 00:10:38:06
anywhere from 100 to
00:10:38:06 - 00:10:39:01
110 pounds
00:10:39:01 - 00:10:40:17
of feed per day.
00:10:40:19 - 00:10:41:18
And so if I put
00:10:41:18 - 00:10:43:08
what's here in my hand,
00:10:43:08 - 00:10:44:09
you know, across
00:10:44:09 - 00:10:45:07
all that feed,
00:10:45:07 - 00:10:47:06
it's pretty.
00:10:47:06 - 00:10:49:03
Pretty,
00:10:49:03 - 00:10:50:02
hard to,
00:10:50:02 - 00:10:50:22
to for them
00:10:50:22 - 00:10:52:00
to sniff it out or taste.
00:10:52:00 - 00:10:53:05
It's neutral.
00:10:53:05 - 00:10:54:13
Neutral,
00:10:54:13 - 00:10:55:07
neutral smelling.
00:10:55:07 - 00:10:56:12
So it's not
00:10:56:12 - 00:10:57:06
palatability
00:10:57:06 - 00:10:58:04
is not so much
00:10:58:04 - 00:10:59:11
an issue for that.
00:10:59:11 - 00:11:00:03
But what we do
00:11:00:03 - 00:11:00:22
to help mask
00:11:00:22 - 00:11:01:07
it in
00:11:01:07 - 00:11:02:16
is we add it to the feed
00:11:02:16 - 00:11:04:22
and let it mix through,
00:11:04:22 - 00:11:06:05
our casserole here.
00:11:06:05 - 00:11:06:20
So that way
00:11:06:20 - 00:11:08:04
that it gets blended up
00:11:08:04 - 00:11:09:17
and so that hopefully
00:11:09:17 - 00:11:10:23
our goal is that in each
00:11:10:23 - 00:11:11:13
and every bite
00:11:11:13 - 00:11:12:15
that cows are consuming,
00:11:12:15 - 00:11:13:06
that they're getting
00:11:13:06 - 00:11:13:18
a little bit
00:11:13:18 - 00:11:14:09
of the additive
00:11:14:09 - 00:11:14:21
as they go.
00:11:14:21 - 00:11:15:09
So that way
00:11:15:09 - 00:11:16:17
it's not a whole bunch
00:11:16:17 - 00:11:17:17
at one point in time.
00:11:17:17 - 00:11:18:08
It's not
00:11:18:08 - 00:11:19:05
there's none here.
00:11:19:05 - 00:11:20:11
So that way,
00:11:20:11 - 00:11:21:08
cows can can
00:11:21:08 - 00:11:22:05
continuously consume it
00:11:22:05 - 00:11:22:18
throughout the day
00:11:22:18 - 00:11:24:04
because this additive
00:11:24:04 - 00:11:25:20
has a limited lifespan
00:11:25:20 - 00:11:27:05
or active life
00:11:27:05 - 00:11:27:23
when it's present
00:11:27:23 - 00:11:28:16
in the gut.
00:11:28:16 - 00:11:29:06
So it has to be
00:11:29:06 - 00:11:29:19
continuously
00:11:29:19 - 00:11:30:23
consumed over time
00:11:30:23 - 00:11:31:06
in order
00:11:31:06 - 00:11:33:02
to have the same effect.
00:11:33:02 - 00:11:33:12
It'd be great
00:11:33:12 - 00:11:34:01
if we could feed it
00:11:34:01 - 00:11:34:14
once a day
00:11:34:14 - 00:11:35:12
and then
00:11:35:12 - 00:11:36:19
have a long term effect,
00:11:36:19 - 00:11:38:08
but unfortunately it's
00:11:38:08 - 00:11:39:02
it has to be
00:11:39:02 - 00:11:39:21
continuously fed
00:11:39:21 - 00:11:41:05
as it's broken down
00:11:41:05 - 00:11:42:07
and passed
00:11:42:07 - 00:11:42:19
out of the animal
00:11:42:19 - 00:11:43:11
at that point.
00:11:43:11 - 00:11:44:02
Make your life a
00:11:44:02 - 00:11:46:09
whole lot easier.
00:11:46:11 - 00:11:46:22
And then from
00:11:46:22 - 00:11:47:07
there, how do
00:11:47:07 - 00:11:47:16
you measure
00:11:47:16 - 00:11:48:07
the emissions?
00:11:48:07 - 00:11:48:23
How do you kind
00:11:48:23 - 00:11:49:10
of understand
00:11:49:10 - 00:11:50:18
if it's working or not?
00:11:50:18 - 00:11:51:01
Yeah.
00:11:51:01 - 00:11:51:23
So we have many
00:11:51:23 - 00:11:52:16
different techniques
00:11:52:16 - 00:11:53:14
that we could utilize
00:11:53:14 - 00:11:54:20
for how we,
00:11:54:20 - 00:11:56:21
accomplish this on farms.
00:11:56:21 - 00:11:57:05
You know,
00:11:57:05 - 00:11:58:06
I think everyone
00:11:58:06 - 00:11:59:05
is interested
00:11:59:05 - 00:12:00:05
and they're wondering,
00:12:00:05 - 00:12:00:18
especially
00:12:00:18 - 00:12:01:09
the undergrads,
00:12:01:09 - 00:12:01:22
when they first come
00:12:01:22 - 00:12:02:08
to the project
00:12:02:08 - 00:12:02:16
that they're like,
00:12:02:16 - 00:12:03:07
how do we actually
00:12:03:07 - 00:12:03:18
measure them?
00:12:03:18 - 00:12:04:02
They're thinking
00:12:04:02 - 00:12:05:01
that they have to chase
00:12:05:01 - 00:12:05:09
the animals
00:12:05:09 - 00:12:06:03
around with bags
00:12:06:03 - 00:12:07:12
or how do we
00:12:07:12 - 00:12:08:08
how do we capture
00:12:08:08 - 00:12:09:02
the emissions
00:12:09:02 - 00:12:09:13
at that point?
00:12:09:13 - 00:12:10:13
You know,
00:12:10:13 - 00:12:11:20
but we have these,
00:12:11:20 - 00:12:13:02
units that are called
00:12:13:02 - 00:12:14:12
greenfeeds.
00:12:14:12 - 00:12:15:06
And the closest thing
00:12:15:06 - 00:12:15:20
that I can say
00:12:15:20 - 00:12:16:13
is that they're basically
00:12:16:13 - 00:12:18:11
breathalyzers for cows
00:12:18:11 - 00:12:20:08
and that the cows are,
00:12:20:08 - 00:12:21:08
individually trained.
00:12:21:08 - 00:12:22:00
Some are easier
00:12:22:00 - 00:12:23:04
than others,
00:12:23:04 - 00:12:24:19
to walk up to a machine,
00:12:24:19 - 00:12:25:12
and they have
00:12:25:12 - 00:12:26:12
tags in each
00:12:26:12 - 00:12:27:12
one of their ears
00:12:27:12 - 00:12:29:11
that says that this cow
00:12:29:11 - 00:12:31:12
cow a b
00:12:31:12 - 00:12:31:18
or call
00:12:31:18 - 00:12:32:20
Abigail and bessy
00:12:32:20 - 00:12:34:12
for that reason,
00:12:34:12 - 00:12:35:08
they come up to
00:12:35:08 - 00:12:36:10
to the machine
00:12:36:10 - 00:12:37:06
and then it says,
00:12:37:06 - 00:12:38:01
Abigail's here.
00:12:38:01 - 00:12:38:18
So then it drops
00:12:38:18 - 00:12:39:15
a little bit of feed
00:12:39:15 - 00:12:40:21
for them to consume.
00:12:40:21 - 00:12:41:17
And while they're eating,
00:12:41:17 - 00:12:42:04
they're
00:12:42:04 - 00:12:43:00
they're constantly
00:12:43:00 - 00:12:43:23
belching and burping
00:12:43:23 - 00:12:44:15
methane throughout
00:12:44:15 - 00:12:45:13
the day.
00:12:45:13 - 00:12:46:09
And we're also interested
00:12:46:09 - 00:12:47:06
in other gases
00:12:47:06 - 00:12:48:15
such as hydrogen, oxygen,
00:12:48:15 - 00:12:50:22
carbon dioxide, as those
00:12:50:22 - 00:12:52:22
can influence metabolism
00:12:52:22 - 00:12:54:02
and give us insights into
00:12:54:02 - 00:12:54:14
what is happening
00:12:54:14 - 00:12:55:17
at the animal level.
00:12:55:17 - 00:12:58:18
So understanding,
00:12:58:20 - 00:12:59:20
how long
00:12:59:20 - 00:13:00:11
animals are there
00:13:00:11 - 00:13:01:05
Theyr’e usually there
00:13:01:05 - 00:13:02:01
at the greenfeed
00:13:02:01 - 00:13:04:09
for about 2 to 3 minutes.
00:13:04:09 - 00:13:05:12
Sometimes some animals
00:13:05:12 - 00:13:06:11
stay longer up
00:13:06:11 - 00:13:08:06
to 5 minutes.
00:13:08:06 - 00:13:09:07
And we take those samples
00:13:09:07 - 00:13:09:21
at different time
00:13:09:21 - 00:13:11:04
points today.
00:13:11:04 - 00:13:11:20
Because of course,
00:13:11:20 - 00:13:12:04
like you
00:13:12:04 - 00:13:12:22
and I, you know,
00:13:12:22 - 00:13:14:14
we consume meals
00:13:14:14 - 00:13:14:22
at different
00:13:14:22 - 00:13:16:07
times of day.
00:13:16:07 - 00:13:17:07
Sometimes we're sleeping.
00:13:17:07 - 00:13:18:08
So you can imagine cows
00:13:18:08 - 00:13:19:15
don't sleep like us,
00:13:19:15 - 00:13:20:16
but they're not eating
00:13:20:16 - 00:13:21:12
so much at night.
00:13:21:12 - 00:13:22:08
So their emissions
00:13:22:08 - 00:13:22:23
are lower
00:13:22:23 - 00:13:23:17
at that point of day.
00:13:23:17 - 00:13:24:18
Whereas after
00:13:24:18 - 00:13:25:20
they take their first big
00:13:25:20 - 00:13:26:14
morning meal
00:13:26:14 - 00:13:27:08
and then emissions
00:13:27:08 - 00:13:27:19
are going to peak.
00:13:27:19 - 00:13:28:07
So interested
00:13:28:07 - 00:13:28:19
in looking at
00:13:28:19 - 00:13:29:14
how do emissions
00:13:29:14 - 00:13:30:19
vary throughout the day.
00:13:30:19 - 00:13:31:15
So they try to come
00:13:31:15 - 00:13:31:22
and go
00:13:31:22 - 00:13:33:03
and get little treats.
00:13:33:03 - 00:13:34:10
Some can go five
00:13:34:10 - 00:13:35:08
six times a day,
00:13:35:08 - 00:13:36:00
which means
00:13:36:00 - 00:13:37:02
they're trying
00:13:37:02 - 00:13:37:09
to check
00:13:37:09 - 00:13:38:03
the candy machine
00:13:38:03 - 00:13:38:23
to see when it's,
00:13:38:23 - 00:13:40:20
whenever it's open.
00:13:40:20 - 00:13:42:22
To get this piece.
00:13:42:22 - 00:13:43:21
So they do not know that
00:13:43:21 - 00:13:44:10
their emissions
00:13:44:10 - 00:13:45:08
have been sampled.
00:13:45:08 - 00:13:45:20
They just think
00:13:45:20 - 00:13:47:04
they're getting a treat.
00:13:47:04 - 00:13:48:06
Which makes it easier,
00:13:48:06 - 00:13:49:14
easier on us to,
00:13:49:14 - 00:13:50:12
to get the data.
00:13:50:12 - 00:13:51:20
Just going to coax them
00:13:51:20 - 00:13:52:15
at first and learn
00:13:52:15 - 00:13:54:09
how to use the machine
00:13:54:09 - 00:13:55:02
and overall
00:13:55:02 - 00:13:55:17
feed additives.
00:13:55:17 - 00:13:56:05
They hold a lot
00:13:56:05 - 00:13:56:20
of promise.
00:13:56:20 - 00:13:57:05
Tell us
00:13:57:05 - 00:13:57:18
just a little bit
00:13:57:18 - 00:13:58:12
about that
00:13:58:12 - 00:13:59:21
and why
00:13:59:21 - 00:14:00:22
they hold so much promise
00:14:00:22 - 00:14:02:16
in mitigating methane.
00:14:02:16 - 00:14:03:00
Yeah.
00:14:03:00 - 00:14:03:23
So you know,
00:14:03:23 - 00:14:04:17
when thinking about,
00:14:04:17 - 00:14:06:12
you know, methane
00:14:06:12 - 00:14:07:12
mitigation, you know,
00:14:07:12 - 00:14:08:16
it's a it's
00:14:08:16 - 00:14:10:14
an up and coming,
00:14:10:16 - 00:14:11:11
area and topic.
00:14:11:11 - 00:14:12:22
And I think,
00:14:12:22 - 00:14:13:16
many countries around
00:14:13:16 - 00:14:13:21
the world
00:14:13:21 - 00:14:14:08
are figuring out
00:14:14:08 - 00:14:15:02
how to do it
00:14:15:02 - 00:14:16:08
because we have so many,
00:14:16:08 - 00:14:17:10
you know,
00:14:17:10 - 00:14:19:23
individual units to
00:14:19:23 - 00:14:21:13
to figure out,
00:14:21:13 - 00:14:22:00
and utilize.
00:14:22:00 - 00:14:23:10
And they talk about the
00:14:23:10 - 00:14:24:01
the downside of
00:14:24:01 - 00:14:24:10
that is
00:14:24:10 - 00:14:24:23
they have to be fed
00:14:24:23 - 00:14:25:21
every day.
00:14:25:21 - 00:14:26:10
But the big
00:14:26:10 - 00:14:27:04
benefit of them
00:14:27:04 - 00:14:28:04
is that
00:14:28:04 - 00:14:29:06
it's ongoing
00:14:29:06 - 00:14:29:23
with the practice
00:14:29:23 - 00:14:31:07
that producers
00:14:31:07 - 00:14:32:16
are already utilizing.
00:14:32:16 - 00:14:33:16
You know, in terms of
00:14:33:16 - 00:14:34:05
we already
00:14:34:05 - 00:14:35:03
utilize additives
00:14:35:03 - 00:14:35:16
that can help
00:14:35:16 - 00:14:36:17
with digestion.
00:14:36:17 - 00:14:38:14
we utilize additives
00:14:38:14 - 00:14:39:01
that can help
00:14:39:01 - 00:14:40:06
with animal health.
00:14:40:06 - 00:14:41:05
Think about
00:14:41:05 - 00:14:42:12
probiotics, prebiotics,
00:14:42:12 - 00:14:43:00
you know, that
00:14:43:00 - 00:14:43:18
we use for humans.
00:14:43:18 - 00:14:44:20
We also use for
00:14:44:20 - 00:14:46:03
for animals as well.
00:14:46:03 - 00:14:49:23
So utilizing a solution
00:14:49:23 - 00:14:51:02
that can one already
00:14:51:02 - 00:14:52:11
be utilized by producers.
00:14:52:11 - 00:14:53:01
You know, it's something
00:14:53:01 - 00:14:53:22
that you just readily
00:14:53:22 - 00:14:54:15
add to the feed
00:14:54:15 - 00:14:57:01
based on what is,
00:14:57:03 - 00:14:57:17
currently already
00:14:57:17 - 00:14:58:22
being done.
00:14:58:22 - 00:14:59:07
Can easily
00:14:59:07 - 00:15:00:10
be applied to that.
00:15:00:10 - 00:15:03:00
And so thinking about
00:15:03:00 - 00:15:03:17
there are a little bit
00:15:03:17 - 00:15:04:09
of technicalities
00:15:04:09 - 00:15:04:20
in terms of
00:15:04:20 - 00:15:05:08
how do you get
00:15:05:08 - 00:15:06:05
the right dosage
00:15:06:05 - 00:15:06:16
and how do you
00:15:06:16 - 00:15:07:20
get the right
00:15:07:20 - 00:15:09:02
consistency on farm
00:15:09:02 - 00:15:09:15
over time.
00:15:09:15 - 00:15:10:22
Because methane, it's
00:15:10:22 - 00:15:11:10
not something
00:15:11:10 - 00:15:12:07
you can easily measure,
00:15:12:07 - 00:15:14:10
like milk or growth
00:15:14:10 - 00:15:16:00
or production.
00:15:16:00 - 00:15:17:05
So thinking about
00:15:17:05 - 00:15:17:23
how do you
00:15:17:23 - 00:15:18:16
standardize that
00:15:18:16 - 00:15:19:12
and how do you
00:15:19:12 - 00:15:20:04
roll it out
00:15:20:04 - 00:15:20:19
has some certain
00:15:20:19 - 00:15:22:02
complexities to it.
00:15:22:02 - 00:15:22:13
But you know,
00:15:22:13 - 00:15:23:21
I think about today
00:15:23:21 - 00:15:25:08
we can feed cows down
00:15:25:08 - 00:15:26:09
to the individual
00:15:26:09 - 00:15:27:07
level of nutrition,
00:15:27:07 - 00:15:27:22
as I think I did
00:15:27:22 - 00:15:28:12
on the podcast
00:15:28:12 - 00:15:29:16
I've talked about here.
00:15:29:16 - 00:15:30:23
You know, I think we're
00:15:30:23 - 00:15:31:20
we are
00:15:31:20 - 00:15:32:22
not in the same front
00:15:32:22 - 00:15:33:14
on methane
00:15:33:14 - 00:15:34:11
environmental things,
00:15:34:11 - 00:15:35:11
but certainly with,
00:15:35:11 - 00:15:36:18
with more time and,
00:15:36:18 - 00:15:38:05
and
00:15:38:05 - 00:15:39:07
technology advances.
00:15:39:07 - 00:15:39:22
I think, you know, we'll
00:15:39:22 - 00:15:40:14
certainly be able
00:15:40:14 - 00:15:41:23
to say one day
00:15:41:23 - 00:15:44:07
that you can be checking
00:15:44:07 - 00:15:44:23
how much methane
00:15:44:23 - 00:15:45:07
or my cow
00:15:45:07 - 00:15:46:01
is producing today
00:15:46:01 - 00:15:46:13
based on it,
00:15:46:13 - 00:15:47:02
and it can be
00:15:47:02 - 00:15:47:12
a number
00:15:47:12 - 00:15:47:22
that's,
00:15:47:22 - 00:15:48:16
you know, up there
00:15:48:16 - 00:15:49:07
and synonymous
00:15:49:07 - 00:15:50:01
with what was milk
00:15:50:01 - 00:15:51:14
production today, as well
00:15:51:14 - 00:15:52:01
as potential
00:15:52:01 - 00:15:53:00
more real world
00:15:53:00 - 00:15:53:11
impact,
00:15:53:11 - 00:15:54:02
which we talk a lot
00:15:54:02 - 00:15:54:14
about at the
00:15:54:14 - 00:15:56:03
Clear Center.
00:15:56:03 - 00:15:56:11
And speaking
00:15:56:11 - 00:15:57:20
of real world impact,
00:15:57:20 - 00:15:58:17
tell me a little bit
00:15:58:17 - 00:15:59:23
about the hours
00:15:59:23 - 00:16:00:09
that you put
00:16:00:09 - 00:16:01:12
this is a real world job
00:16:01:12 - 00:16:02:10
that these
00:16:02:10 - 00:16:05:00
researchers do out at,
00:16:05:02 - 00:16:06:09
the dairy and out at
00:16:06:09 - 00:16:07:16
the feedlot
00:16:07:16 - 00:16:08:09
when you were in the
00:16:08:09 - 00:16:09:09
heart of this study.
00:16:09:09 - 00:16:09:22
I mean, tell us
00:16:09:22 - 00:16:10:15
about the hours,
00:16:10:15 - 00:16:10:23
what time
00:16:10:23 - 00:16:11:11
you would get out
00:16:11:11 - 00:16:12:04
at the dairy,
00:16:12:04 - 00:16:13:01
what time you would
00:16:13:01 - 00:16:14:05
leave the dairy,
00:16:14:05 - 00:16:14:15
how many people
00:16:14:15 - 00:16:15:06
were working on
00:16:15:06 - 00:16:15:14
the study?
00:16:15:14 - 00:16:15:22
Just tell us
00:16:15:22 - 00:16:16:16
a little bit about that,
00:16:16:16 - 00:16:17:02
because I think
00:16:17:02 - 00:16:17:15
it's amazing.
00:16:17:15 - 00:16:19:05
I brag on you guys a lot
00:16:19:05 - 00:16:19:22
because when we're
00:16:19:22 - 00:16:20:17
having vacation
00:16:20:17 - 00:16:21:09
or we're
00:16:21:09 - 00:16:22:14
having a weekend,
00:16:22:14 - 00:16:23:02
you guys are
00:16:23:02 - 00:16:24:01
still working.
00:16:24:01 - 00:16:24:07
Yeah.
00:16:24:07 - 00:16:25:02
I mean,
00:16:25:02 - 00:16:25:17
there was
00:16:25:17 - 00:16:26:14
this period of time
00:16:26:14 - 00:16:28:07
where, you know, I didn't
00:16:28:07 - 00:16:29:17
I saw my house,
00:16:29:17 - 00:16:30:18
I saw the dairy farm,
00:16:30:18 - 00:16:31:09
and I saw
00:16:31:09 - 00:16:32:16
the lab here in Meyer
00:16:32:16 - 00:16:33:04
and the
00:16:33:04 - 00:16:33:17
maybe the grocery
00:16:33:17 - 00:16:34:04
store too.
00:16:34:04 - 00:16:35:04
That was the only
00:16:35:04 - 00:16:36:04
one that too.
00:16:36:04 - 00:16:37:13
but besides that,
00:16:37:13 - 00:16:37:21
you know,
00:16:37:21 - 00:16:38:16
every single morning,
00:16:38:16 - 00:16:39:07
it's not just me.
00:16:39:07 - 00:16:39:18
There's a lot
00:16:39:18 - 00:16:40:11
of other undergrads,
00:16:40:11 - 00:16:41:04
a lot of other folks
00:16:41:04 - 00:16:41:13
that are working
00:16:41:13 - 00:16:42:01
on the project
00:16:42:01 - 00:16:42:12
to make this
00:16:42:12 - 00:16:43:10
all happen now
00:16:43:10 - 00:16:44:15
and into the future.
00:16:44:15 - 00:16:46:18
But, when we start,
00:16:46:18 - 00:16:47:19
when they start milking
00:16:47:19 - 00:16:48:15
cows, each
00:16:48:15 - 00:16:50:12
morning at 4 a.m.
00:16:50:14 - 00:16:51:19
And cows
00:16:51:19 - 00:16:52:14
get milked twice a day,
00:16:52:14 - 00:16:53:10
so that's 4 a.m.
00:16:53:10 - 00:16:54:20
And 4 p.m.
00:16:54:20 - 00:16:55:06
And that can
00:16:55:06 - 00:16:55:22
last anywhere
00:16:55:22 - 00:16:58:09
from 3 to 4 hours,
00:16:58:09 - 00:16:59:07
to feed
00:16:59:07 - 00:17:00:03
every single animal.
00:17:00:03 - 00:17:01:04
Because we have several
00:17:01:04 - 00:17:01:23
different diets
00:17:01:23 - 00:17:02:18
across several
00:17:02:18 - 00:17:03:23
different points in time.
00:17:03:23 - 00:17:05:12
Plus we have to take
00:17:05:12 - 00:17:05:21
figure out
00:17:05:21 - 00:17:06:16
what they didn't eat
00:17:06:16 - 00:17:07:06
so we can figure out
00:17:07:06 - 00:17:08:03
how much to feed them
00:17:08:03 - 00:17:08:11
for the
00:17:08:11 - 00:17:09:17
for the following day.
00:17:09:17 - 00:17:10:21
And so it's,
00:17:10:21 - 00:17:11:10
it's this,
00:17:11:10 - 00:17:12:16
this very
00:17:12:16 - 00:17:13:08
intricate system,
00:17:13:08 - 00:17:13:15
you know,
00:17:13:15 - 00:17:14:17
I’d love to just show up
00:17:14:17 - 00:17:15:08
and just be able to
00:17:15:08 - 00:17:16:10
feed all the animals
00:17:16:10 - 00:17:18:06
one given feed
00:17:18:06 - 00:17:19:05
But we got to figure out,
00:17:19:05 - 00:17:19:22
you know, exactly
00:17:19:22 - 00:17:21:09
what to do,
00:17:21:09 - 00:17:22:05
how much they didn't eat,
00:17:22:05 - 00:17:22:14
how much they
00:17:22:14 - 00:17:23:05
are going to eat.
00:17:23:05 - 00:17:23:16
And that's all
00:17:23:16 - 00:17:24:18
part of these,
00:17:24:18 - 00:17:25:02
you know,
00:17:25:02 - 00:17:26:03
bigger
00:17:26:03 - 00:17:27:12
long term
00:17:27:12 - 00:17:28:04
study pieces
00:17:28:04 - 00:17:28:13
that are going
00:17:28:13 - 00:17:29:20
to come together.
00:17:29:20 - 00:17:30:11
Plus there's a lot
00:17:30:11 - 00:17:31:01
of different,
00:17:31:01 - 00:17:31:23
you know, maintenance
00:17:31:23 - 00:17:32:08
and cleaning
00:17:32:08 - 00:17:32:21
that all happens
00:17:32:21 - 00:17:33:13
in the background.
00:17:33:13 - 00:17:34:02
to all make
00:17:34:02 - 00:17:34:18
that possible.
00:17:34:18 - 00:17:36:17
So it's things that,
00:17:36:17 - 00:17:37:09
you know, happen
00:17:37:09 - 00:17:38:16
Monday through Friday,
00:17:38:16 - 00:17:40:00
Saturday and Sunday
00:17:40:00 - 00:17:41:10
and will be here
00:17:41:10 - 00:17:41:23
in the upcoming
00:17:41:23 - 00:17:43:19
holiday season as well,
00:17:43:19 - 00:17:44:22
to all make that happen.
00:17:44:22 - 00:17:46:05
So it's
00:17:46:05 - 00:17:46:20
it's certainly
00:17:46:20 - 00:17:47:15
a lot of work.
00:17:47:15 - 00:17:49:01
But you know,
00:17:49:01 - 00:17:50:04
people
00:17:50:04 - 00:17:51:14
like myself are in this
00:17:51:14 - 00:17:52:03
because it's
00:17:52:03 - 00:17:53:07
for the passion,
00:17:53:07 - 00:17:54:00
and what people
00:17:54:00 - 00:17:55:02
really enjoy to do
00:17:55:02 - 00:17:55:22
and being part of it.
00:17:55:22 - 00:17:56:14
And so,
00:17:56:14 - 00:17:58:05
you know, really
00:17:58:05 - 00:17:59:08
thankful to be a part
00:17:59:08 - 00:18:00:06
of these opportunities.
00:18:00:06 - 00:18:00:21
I didn't want to say that
00:18:00:21 - 00:18:01:09
I want to do it
00:18:01:09 - 00:18:02:06
every single day,
00:18:02:06 - 00:18:03:10
but, you know,
00:18:03:10 - 00:18:04:19
I like doing this
00:18:04:19 - 00:18:05:18
because this is what
00:18:05:18 - 00:18:06:06
we enjoy.
00:18:06:06 - 00:18:07:04
I want to be a part of.
00:18:07:04 - 00:18:07:18
And so that
00:18:07:18 - 00:18:08:14
that makes it,
00:18:08:14 - 00:18:09:06
you know,
00:18:09:06 - 00:18:10:08
something enjoyable
00:18:10:08 - 00:18:11:15
and it really makes
00:18:11:15 - 00:18:12:22
a PHD in Animal science.
00:18:12:22 - 00:18:15:09
Like it's certainly
00:18:15:09 - 00:18:16:00
we have skill
00:18:16:00 - 00:18:17:08
sets in a labs.
00:18:17:08 - 00:18:17:23
We have skill sets
00:18:17:23 - 00:18:18:14
in animals,
00:18:18:14 - 00:18:19:09
we have skill sets
00:18:19:09 - 00:18:20:09
in total,
00:18:20:09 - 00:18:21:04
total work ethic,
00:18:21:04 - 00:18:22:08
which gives us
00:18:22:08 - 00:18:23:15
so many skill sets to
00:18:23:15 - 00:18:24:05
to be set up
00:18:24:05 - 00:18:25:01
for the next thing here
00:18:25:01 - 00:18:25:23
and especially here,
00:18:25:23 - 00:18:26:04
as part
00:18:26:04 - 00:18:26:19
of the CLEAR Center
00:18:26:19 - 00:18:27:12
with the opportunities
00:18:27:12 - 00:18:27:18
that we get
00:18:27:18 - 00:18:28:11
to take part in
00:18:28:11 - 00:18:30:00
for research.
00:18:30:00 - 00:18:31:00
Well, being at a dairy
00:18:31:00 - 00:18:31:10
at 4 a.m.
00:18:31:10 - 00:18:31:23
might not be your
00:18:31:23 - 00:18:32:14
favorite memory,
00:18:32:14 - 00:18:33:04
but what do you
00:18:33:04 - 00:18:34:06
what's your
00:18:34:06 - 00:18:34:22
favorite memory
00:18:34:22 - 00:18:35:14
at UC Davis
00:18:35:14 - 00:18:35:22
or at the
00:18:35:22 - 00:18:36:18
clear Center, maybe.
00:18:36:18 - 00:18:37:19
What can you talk about?
00:18:37:19 - 00:18:38:13
A favorite memory
00:18:38:13 - 00:18:39:07
or a favorite event
00:18:39:07 - 00:18:41:02
you were part of or.
00:18:41:02 - 00:18:41:12
Yeah.
00:18:41:12 - 00:18:42:19
So, you know,
00:18:42:19 - 00:18:43:15
I've been having
00:18:43:15 - 00:18:44:20
a lot of unique
00:18:44:20 - 00:18:45:09
opportunities
00:18:45:09 - 00:18:46:03
and experiences here
00:18:46:03 - 00:18:46:10
as part of the
00:18:46:10 - 00:18:46:23
Career Center
00:18:46:23 - 00:18:47:15
that I know
00:18:47:15 - 00:18:48:19
that I would not have had
00:18:48:19 - 00:18:49:09
if I had gone to
00:18:49:09 - 00:18:51:02
another program.
00:18:51:04 - 00:18:51:15
But being
00:18:51:15 - 00:18:53:05
part of the clear center
00:18:53:05 - 00:18:54:09
and dr. Mitloehner’s
00:18:54:09 - 00:18:55:09
work
00:18:55:09 - 00:18:55:21
being able
00:18:55:21 - 00:18:56:10
to attend
00:18:56:10 - 00:18:57:10
the Sustainable Livestock
00:18:57:10 - 00:18:58:02
Transformation
00:18:58:02 - 00:18:59:17
Conference, at FAO
00:18:59:17 - 00:19:00:20
as being,
00:19:00:20 - 00:19:01:17
serving as a delegate
00:19:01:17 - 00:19:03:13
representing the U.S.
00:19:03:13 - 00:19:04:11
along there
00:19:04:11 - 00:19:05:06
with dr. Mitloehner
00:19:05:06 - 00:19:06:03
and being there in Rome
00:19:06:03 - 00:19:06:20
and hearing
00:19:06:20 - 00:19:07:16
like how
00:19:07:16 - 00:19:08:14
this collaboration
00:19:08:14 - 00:19:10:05
around methane emissions
00:19:10:05 - 00:19:10:17
and livestock
00:19:10:17 - 00:19:11:20
sustainability
00:19:11:20 - 00:19:12:21
is really evolving.
00:19:12:21 - 00:19:13:11
You know,
00:19:13:11 - 00:19:14:07
I think
00:19:14:07 - 00:19:15:09
Frank walks
00:19:15:09 - 00:19:16:14
around everywhere there
00:19:16:14 - 00:19:17:19
and everyone knows him.
00:19:17:19 - 00:19:19:15
And because of the
00:19:19:15 - 00:19:20:12
the conversation
00:19:20:12 - 00:19:21:21
that he's brought around
00:19:21:21 - 00:19:22:23
livestock sustainability.
00:19:22:23 - 00:19:23:19
And I think about
00:19:23:19 - 00:19:24:05
all these
00:19:24:05 - 00:19:24:18
different people
00:19:24:18 - 00:19:25:03
and all these
00:19:25:03 - 00:19:25:17
different countries
00:19:25:17 - 00:19:27:01
are working together.
00:19:27:01 - 00:19:28:01
And exciting to see
00:19:28:01 - 00:19:28:22
and thinking about
00:19:28:22 - 00:19:30:05
how much momentum
00:19:30:05 - 00:19:31:02
is out there right now
00:19:31:02 - 00:19:31:16
and how much
00:19:31:16 - 00:19:32:12
is coming together.
00:19:32:12 - 00:19:33:21
It was really eye opening
00:19:33:21 - 00:19:35:23
because we talk about,
00:19:35:23 - 00:19:36:13
opportunities
00:19:36:13 - 00:19:37:06
for solutions here
00:19:37:06 - 00:19:38:17
in the United States.
00:19:38:17 - 00:19:39:04
And that's not going
00:19:39:04 - 00:19:40:00
to work everywhere,
00:19:40:00 - 00:19:40:21
because not everywhere
00:19:40:21 - 00:19:42:18
has livestock systems
00:19:42:18 - 00:19:43:16
or things
00:19:43:16 - 00:19:44:09
of sustainability
00:19:44:09 - 00:19:45:17
in the same way,
00:19:45:17 - 00:19:46:16
as we do.
00:19:46:16 - 00:19:47:10
Plus,
00:19:47:10 - 00:19:47:20
you know,
00:19:47:20 - 00:19:48:14
majority of
00:19:48:14 - 00:19:50:01
the animals are
00:19:50:01 - 00:19:51:10
located elsewhere
00:19:51:10 - 00:19:53:01
all around the world.
00:19:53:01 - 00:19:53:17
And so it
00:19:53:17 - 00:19:54:10
just thinks about
00:19:54:10 - 00:19:55:02
how can we think
00:19:55:02 - 00:19:56:01
about solutions
00:19:56:01 - 00:19:58:04
that are not one work
00:19:58:04 - 00:19:59:08
here in the US or work
00:19:59:08 - 00:20:01:02
in other environments?
00:20:01:02 - 00:20:01:15
Because at the
00:20:01:15 - 00:20:02:15
end of the day,
00:20:02:15 - 00:20:03:10
we're
00:20:03:10 - 00:20:03:22
thinking about
00:20:03:22 - 00:20:04:21
how can we
00:20:04:21 - 00:20:06:01
improve nutrition,
00:20:06:01 - 00:20:07:20
how can we reduce
00:20:07:20 - 00:20:08:15
environmental impacts,
00:20:08:15 - 00:20:10:08
and how can we help with,
00:20:10:08 - 00:20:11:03
you know,
00:20:11:03 - 00:20:12:07
the billions of people
00:20:12:07 - 00:20:13:04
that are involved
00:20:13:04 - 00:20:15:01
in livestock systems
00:20:15:01 - 00:20:17:12
today, which is
00:20:17:12 - 00:20:20:04
makes this a consistent,
00:20:20:04 - 00:20:20:22
and challenging issue
00:20:20:22 - 00:20:22:13
that will continue to
00:20:22:13 - 00:20:23:01
think about
00:20:23:01 - 00:20:23:16
how do we create
00:20:23:16 - 00:20:24:05
more sustainable
00:20:24:05 - 00:20:24:19
food systems,
00:20:24:19 - 00:20:25:11
at least for,
00:20:25:11 - 00:20:26:11
for the rest of my,
00:20:26:11 - 00:20:28:13
my career here. So.
00:20:28:13 - 00:20:28:19
Well,
00:20:28:19 - 00:20:29:03
and speaking
00:20:29:03 - 00:20:29:15
of your career,
00:20:29:15 - 00:20:30:00
as we wrap
00:20:30:00 - 00:20:31:07
things up here, what
00:20:31:07 - 00:20:32:02
what are your goals
00:20:32:02 - 00:20:33:00
with your future,
00:20:33:00 - 00:20:34:01
with your research
00:20:34:01 - 00:20:34:17
or personally,
00:20:34:17 - 00:20:35:03
what do you want
00:20:35:03 - 00:20:36:11
to do from here on out?
00:20:36:11 - 00:20:36:20
Yeah, I know
00:20:36:20 - 00:20:37:06
that's all a
00:20:37:06 - 00:20:37:19
great question
00:20:37:19 - 00:20:38:06
to think about.
00:20:38:06 - 00:20:39:13
What comes next for me
00:20:39:13 - 00:20:39:20
here?
00:20:39:20 - 00:20:42:09
as of today's taping,
00:20:42:09 - 00:20:42:23
I have not
00:20:42:23 - 00:20:43:14
figured out what
00:20:43:14 - 00:20:44:13
what comes next for me
00:20:44:13 - 00:20:45:10
just yet.
00:20:45:10 - 00:20:48:01
But, you know what?
00:20:48:01 - 00:20:48:18
What I want
00:20:48:18 - 00:20:49:13
to be involved in
00:20:49:13 - 00:20:50:04
and what I want to take
00:20:50:04 - 00:20:50:14
part in
00:20:50:14 - 00:20:51:14
is thinking about
00:20:51:14 - 00:20:53:14
working with various
00:20:53:14 - 00:20:55:00
different food companies
00:20:55:00 - 00:20:55:17
at this point
00:20:55:17 - 00:20:56:03
and thinking
00:20:56:03 - 00:20:57:07
about understanding
00:20:57:07 - 00:20:58:22
and providing
00:20:58:22 - 00:20:59:16
technical expertise
00:20:59:16 - 00:21:00:04
and background
00:21:00:04 - 00:21:01:15
that I've been able to
00:21:01:15 - 00:21:02:08
accrue here
00:21:02:08 - 00:21:03:10
through the clear center
00:21:03:10 - 00:21:03:23
and thinking about
00:21:03:23 - 00:21:04:14
how do we
00:21:04:14 - 00:21:05:13
actually implement
00:21:05:13 - 00:21:06:07
these opportunities
00:21:06:07 - 00:21:06:20
on farms
00:21:06:20 - 00:21:07:11
that I've worked out.
00:21:07:11 - 00:21:08:10
So that's the feed additives,
00:21:08:10 - 00:21:08:18
that's the
00:21:08:18 - 00:21:10:09
accounting systems.
00:21:10:09 - 00:21:10:23
And thinking about
00:21:10:23 - 00:21:12:04
how do we apply
00:21:12:04 - 00:21:13:01
those on farms
00:21:13:01 - 00:21:13:12
and how do we
00:21:13:12 - 00:21:14:07
track, verify
00:21:14:07 - 00:21:14:21
and measure them
00:21:14:21 - 00:21:17:02
through the
00:21:17:02 - 00:21:18:06
the supply chain.
00:21:18:06 - 00:21:19:03
So like
00:21:19:03 - 00:21:20:01
what you're going to go
00:21:20:01 - 00:21:21:14
buy at the grocery store
00:21:21:14 - 00:21:23:07
that has this
00:21:23:07 - 00:21:24:01
this reduction
00:21:24:01 - 00:21:25:09
at the end of the day.
00:21:25:09 - 00:21:26:11
Because I think there's
00:21:26:11 - 00:21:27:20
tremendous opportunity
00:21:27:20 - 00:21:29:19
there at this point.
00:21:29:21 - 00:21:30:08
There's still a
00:21:30:08 - 00:21:31:04
little bit of
00:21:31:04 - 00:21:31:19
figuring out
00:21:31:19 - 00:21:32:21
that people are doing,
00:21:32:21 - 00:21:34:05
but I think it's,
00:21:34:05 - 00:21:34:18
a very
00:21:34:18 - 00:21:35:12
exciting opportunity
00:21:35:12 - 00:21:36:00
to have, like,
00:21:36:00 - 00:21:37:03
a real world impact
00:21:37:03 - 00:21:38:12
from what this,
00:21:38:12 - 00:21:40:06
this area of research
00:21:40:06 - 00:21:40:23
has turned to be.
00:21:40:23 - 00:21:42:07
So,
00:21:42:07 - 00:21:43:06
what that looks like
00:21:43:06 - 00:21:43:23
and where that's at,
00:21:43:23 - 00:21:45:11
that's still
00:21:45:11 - 00:21:46:16
to be determined.
00:21:46:16 - 00:21:47:23
But, you know,
00:21:47:23 - 00:21:48:15
looking forward
00:21:48:15 - 00:21:49:03
to have lots
00:21:49:03 - 00:21:50:04
of exciting years ahead
00:21:50:04 - 00:21:51:07
in terms of where,
00:21:51:07 - 00:21:51:23
where this will go
00:21:51:23 - 00:21:54:05
from here. So,
00:21:54:05 - 00:21:55:00
I'm looking forward
00:21:55:00 - 00:21:55:15
to certainly not
00:21:55:15 - 00:21:56:17
waking up at 4 a.m.
00:21:56:17 - 00:21:57:05
all the time
00:21:57:05 - 00:21:59:06
anymore, but,
00:21:59:06 - 00:22:01:09
that is the next step
00:22:01:09 - 00:22:02:05
for me as,
00:22:02:05 - 00:22:03:18
as I look to wrap up here
00:22:03:18 - 00:22:04:09
in the next
00:22:04:09 - 00:22:05:08
couple of weeks.
00:22:05:08 - 00:22:05:22
Well, excellent.
00:22:05:22 - 00:22:06:15
Your future is bright.
00:22:06:15 - 00:22:06:21
Conor.
00:22:06:21 - 00:22:07:11
Thank you so much
00:22:07:11 - 00:22:08:14
for all of your work
00:22:08:14 - 00:22:09:14
here at the Clear Center.
00:22:09:14 - 00:22:10:08

00:22:11:14 - 00:22:12:07
knowledge with us.
00:22:12:07 - 00:22:12:19
And thank you
00:22:12:19 - 00:22:13:08

00:22:14:09 - 00:22:14:15
We'll see you
00:22:14:15 - 00:22:15:06
again next time.
By UC Davis CLEAR CenterConor McCabe sits down with CLEAR Conversations host, Tracy Sellers. At the CLEAR Center at UC Davis, researchers spend their days asking a big question with global stakes: how can we raise livestock in ways that are more climate-friendly? For PhD student Conor McCabe, now approaching the end of his fifth year in the Mitloehner Lab, that question has fueled not just one research project—but nearly an entire year of long days, early mornings, and a sprawling scientific effort that spans animals, microbes, emissions, and the future of food systems.
McCabe didn’t start out as a dairy kid. He grew up on a small farm in Oregon—“pretty much an Old McDonald’s farm,” he jokes—with pigs, cattle, pumpkins, and Christmas trees. His mother once served as a dairy princess, but dairy cattle weren’t part of Connor’s life until college. After studying animal science across Cornell, Purdue, and now UC Davis, he’s seen “different pockets of cows across the country,” as he puts it. But it wasn’t until arriving at Davis that he found the right intersection of ruminant biology and real-world impact.

00:00:00:00 - 00:00:00:11
Because at the
00:00:00:11 - 00:00:01:07
end of the day,
00:00:01:07 - 00:00:02:06
what we're
00:00:02:06 - 00:00:02:18
thinking about
00:00:02:18 - 00:00:03:19
how can we
00:00:03:19 - 00:00:04:22
improve nutrition,
00:00:04:22 - 00:00:06:07
how can we reduce
00:00:06:07 - 00:00:07:02
environmental impacts,
00:00:07:02 - 00:00:08:12
and how can we help with
00:00:08:12 - 00:00:09:09
the billions of people
00:00:09:09 - 00:00:10:12
that are involved
00:00:10:12 - 00:00:12:01
in livestock systems.
00:00:12:01 - 00:00:12:12
Think about
00:00:12:12 - 00:00:13:08
how do we create more
00:00:13:08 - 00:00:14:07
sustainable food systems,
00:00:14:07 - 00:00:14:23
at least for
00:00:14:23 - 00:00:15:23
for the rest of my
00:00:15:23 - 00:00:23:10
my career here.
00:00:23:12 - 00:00:24:03
Welcome to
00:00:24:03 - 00:00:25:14
Clear Conversations.
00:00:25:14 - 00:00:25:20
You know,
00:00:25:20 - 00:00:26:11
the clear center.
00:00:26:11 - 00:00:27:03
Our researchers
00:00:27:03 - 00:00:27:23
are testing ways
00:00:27:23 - 00:00:28:19
to make livestock
00:00:28:19 - 00:00:30:01
more climate friendly.
00:00:30:01 - 00:00:30:10
And today,
00:00:30:10 - 00:00:31:02
we're going to be talking
00:00:31:02 - 00:00:31:08
to one of
00:00:31:08 - 00:00:32:08
those researchers.
00:00:32:08 - 00:00:32:21
His name is
00:00:32:21 - 00:00:33:13
Conor McCabe,
00:00:33:13 - 00:00:34:10
and he's a
00:00:34:10 - 00:00:35:06
PhD student in the
00:00:35:06 - 00:00:36:07
Mitloehner lab.
00:00:36:07 - 00:00:36:20
He is working
00:00:36:20 - 00:00:38:00
with feed additives
00:00:38:00 - 00:00:38:17
with dairy cows.
00:00:38:17 - 00:00:39:09
And he's going to tell us
00:00:39:09 - 00:00:39:20
a little bit
00:00:39:20 - 00:00:41:01
about his research today.
00:00:41:01 - 00:00:41:09
Conor,
00:00:41:09 - 00:00:42:07
thanks for joining us.
00:00:42:07 - 00:00:43:11
I'm so happy to be here
00:00:43:11 - 00:00:44:01
and looking
00:00:44:01 - 00:00:44:13
forward to it.
00:00:44:13 - 00:00:45:02
All right.
00:00:45:02 - 00:00:45:21
We are looking forward
00:00:45:21 - 00:00:46:13
to talking to you.
00:00:46:13 - 00:00:47:04
So first of all,
00:00:47:04 - 00:00:47:18
tell us a little bit
00:00:47:18 - 00:00:48:13
about yourself
00:00:48:13 - 00:00:49:06
and your background.
00:00:49:06 - 00:00:50:16
You've done a lot,
00:00:50:16 - 00:00:50:22
even
00:00:50:22 - 00:00:51:18
before you came to UC
00:00:51:18 - 00:00:52:13
Davis. You've done a lot.
00:00:52:13 - 00:00:53:04
So tell us a little bit
00:00:53:04 - 00:00:54:00
about that. Yeah.
00:00:54:00 - 00:00:55:07
So I'm currently
00:00:55:07 - 00:00:55:23
wrapping up
00:00:55:23 - 00:00:57:03
the fifth year of my,
00:00:57:03 - 00:00:58:20
my PhD here at Davis.
00:00:58:20 - 00:01:00:08
The last couple of months
00:01:00:08 - 00:01:01:02
of my time
00:01:01:02 - 00:01:02:09
is coming up here,
00:01:02:09 - 00:01:03:08
but I'm originally
00:01:03:08 - 00:01:04:04
from the West Coast,
00:01:04:04 - 00:01:05:14
originally from Oregon
00:01:05:14 - 00:01:06:11
as my hometown where
00:01:06:11 - 00:01:08:02
my family has a
00:01:08:02 - 00:01:10:05
small farm where we have,
00:01:10:05 - 00:01:11:11
pigs,
00:01:11:11 - 00:01:12:15
cattle, Christmas
00:01:12:15 - 00:01:14:10
trees, pumpkins,
00:01:14:12 - 00:01:15:03
all that order.
00:01:15:03 - 00:01:15:19
So a big
00:01:15:19 - 00:01:17:11
old McDonald farm,
00:01:17:11 - 00:01:18:11
and that got my interest
00:01:18:11 - 00:01:20:22
in animal science.
00:01:20:22 - 00:01:21:19
And then
00:01:21:19 - 00:01:22:18
I went to New York,
00:01:22:18 - 00:01:24:10
to Cornell for undergrad,
00:01:24:10 - 00:01:25:16
did a masters at Purdue,
00:01:25:16 - 00:01:26:05
and now
00:01:26:05 - 00:01:26:22
I've come here to UC
00:01:26:22 - 00:01:28:00
Davis.
00:01:28:00 - 00:01:28:12
There's cows
00:01:28:12 - 00:01:29:05
across the country.
00:01:29:05 - 00:01:29:19
So I've kind of seen
00:01:29:19 - 00:01:30:09
a little different
00:01:30:09 - 00:01:31:18
pockets of,
00:01:31:18 - 00:01:33:10
cows throughout my work.
00:01:33:10 - 00:01:34:06
My mom was a dairy
00:01:34:06 - 00:01:35:13
princess growing up,
00:01:35:13 - 00:01:36:15
but we had no,
00:01:36:15 - 00:01:37:12
no experience
00:01:37:12 - 00:01:38:10
or affiliation
00:01:38:10 - 00:01:39:11
with dairy cattle myself
00:01:39:11 - 00:01:39:22
because the cows
00:01:39:22 - 00:01:40:12
were sold off
00:01:40:12 - 00:01:42:07
before I was born.
00:01:42:07 - 00:01:43:05
But it came
00:01:43:05 - 00:01:43:21
on back to me,
00:01:43:21 - 00:01:44:08
and I've since
00:01:44:08 - 00:01:45:01
been involved
00:01:45:01 - 00:01:45:22
ever since here
00:01:45:22 - 00:01:46:08
with different
00:01:46:08 - 00:01:47:11
research projects
00:01:47:11 - 00:01:49:03
across different places
00:01:49:03 - 00:01:49:16
of the country.
00:01:49:16 - 00:01:50:19
And I knew all along
00:01:50:19 - 00:01:51:10
that I had an interest
00:01:51:10 - 00:01:51:21
in coming back
00:01:51:21 - 00:01:52:17
to the West Coast.
00:01:52:17 - 00:01:54:08
I had an interest in,
00:01:54:08 - 00:01:54:16
looking
00:01:54:16 - 00:01:55:02
at the
00:01:55:02 - 00:01:55:20
environmental
00:01:55:20 - 00:01:56:13
opportunities
00:01:56:13 - 00:01:58:02
in animal agriculture.
00:01:58:02 - 00:01:58:15
And UC Davis
00:01:58:15 - 00:01:59:09
was really the place
00:01:59:09 - 00:02:00:07
for that to be
00:02:00:07 - 00:02:01:04
and for me to come to.
00:02:01:04 - 00:02:02:10
So,
00:02:02:12 - 00:02:03:14
this lab and this
00:02:03:14 - 00:02:04:08
opportunity here
00:02:04:08 - 00:02:05:02
with Dr. Mitloehner
00:02:05:02 - 00:02:05:14
really checked
00:02:05:14 - 00:02:06:09
all those boxes
00:02:06:09 - 00:02:08:01
and then led into me
00:02:08:01 - 00:02:08:21
coming here to
00:02:08:21 - 00:02:10:07
to Davis five years ago.
00:02:10:07 - 00:02:11:02
Where were I
00:02:11:02 - 00:02:11:08
I know
00:02:11:08 - 00:02:11:20
I'm in
00:02:11:20 - 00:02:12:15
the final stages
00:02:12:15 - 00:02:13:19
right now, so why
00:02:13:19 - 00:02:14:10
why dairy cows
00:02:14:10 - 00:02:15:06
and why sustainability?
00:02:15:06 - 00:02:15:18
Why was that
00:02:15:18 - 00:02:16:12
interesting to you?
00:02:16:12 - 00:02:17:04
Why did you know
00:02:17:04 - 00:02:18:09
you wanted to do that?
00:02:18:09 - 00:02:18:17
Yeah.
00:02:18:17 - 00:02:20:21
So I think there's
00:02:20:21 - 00:02:21:09
I mean, it's
00:02:21:09 - 00:02:22:05
one of the hottest topics
00:02:22:05 - 00:02:24:19
for sure right now.
00:02:24:19 - 00:02:25:06
You know,
00:02:25:06 - 00:02:26:01
I had a lot of
00:02:26:01 - 00:02:26:22
opportunities with pigs,
00:02:26:22 - 00:02:27:05
and that's
00:02:27:05 - 00:02:27:23
actually my first
00:02:27:23 - 00:02:30:10
entryway to,
00:02:30:10 - 00:02:31:09
to livestock.
00:02:31:09 - 00:02:32:05
But then when I
00:02:32:05 - 00:02:33:12
went to undergrad,
00:02:33:12 - 00:02:34:19
the only opportunity
00:02:34:19 - 00:02:35:05
to get involved
00:02:35:05 - 00:02:35:13
in production
00:02:35:13 - 00:02:36:19
agriculture was
00:02:36:19 - 00:02:38:05
dairy cattle.
00:02:38:05 - 00:02:38:15
Because that's
00:02:38:15 - 00:02:40:22
what Cornell offered.
00:02:40:22 - 00:02:42:02
And, you know, at
00:02:42:02 - 00:02:42:10
first
00:02:42:10 - 00:02:43:12
I started learning more.
00:02:43:12 - 00:02:43:21
So I gained
00:02:43:21 - 00:02:44:12
a liking to it.
00:02:44:12 - 00:02:45:13
And then really
00:02:45:13 - 00:02:46:20
seeing opportunities
00:02:46:20 - 00:02:47:20
are open to you
00:02:47:20 - 00:02:48:13
through what
00:02:48:13 - 00:02:49:12
I had in undergrad,
00:02:49:12 - 00:02:50:04
from research,
00:02:50:04 - 00:02:51:18
from teaching, from,
00:02:51:18 - 00:02:52:21
on farm opportunities.
00:02:52:21 - 00:02:53:09
You know,
00:02:53:09 - 00:02:54:09
no dairy farm
00:02:54:09 - 00:02:55:20
is the same, you know,
00:02:55:20 - 00:02:57:04
in terms of management,
00:02:57:04 - 00:02:57:15
in terms
00:02:57:15 - 00:02:58:17
of different practices,
00:02:58:17 - 00:02:59:03
in terms
00:02:59:03 - 00:03:00:10
of what different
00:03:00:10 - 00:03:01:15
situations,
00:03:01:15 - 00:03:02:11
are spread out
00:03:02:11 - 00:03:03:20
and like the different
00:03:03:20 - 00:03:04:19
management strategies.
00:03:04:19 - 00:03:05:12
I felt like, wow,
00:03:05:12 - 00:03:06:05
this is really cool.
00:03:06:05 - 00:03:06:17
There's a lot of
00:03:06:17 - 00:03:08:14
opportunities here.
00:03:08:16 - 00:03:09:09
Plus, I
00:03:09:09 - 00:03:10:08
really enjoy butter,
00:03:10:08 - 00:03:11:04
ice cream, cheese,
00:03:11:04 - 00:03:12:08
like many of us do
00:03:12:08 - 00:03:13:06
other points
00:03:13:06 - 00:03:14:05
So it's been,
00:03:14:05 - 00:03:16:00
been a cool opportunity point
00:03:16:00 - 00:03:16:13
But I know a lot of
00:03:16:13 - 00:03:17:02
people are interested
00:03:17:02 - 00:03:17:19
about sustainability
00:03:17:19 - 00:03:18:06
and thinking about
00:03:18:06 - 00:03:19:09
what is
00:03:19:09 - 00:03:20:22
the role of dairy cattle
00:03:20:22 - 00:03:22:08
in livestock systems.
00:03:22:08 - 00:03:23:15
And, you know,
00:03:23:15 - 00:03:24:08
I have those
00:03:24:08 - 00:03:25:22
same questions, too,
00:03:25:22 - 00:03:26:15
coming up, in terms
00:03:26:15 - 00:03:28:09
of what our opportunities
00:03:28:09 - 00:03:29:20
here, where
00:03:29:20 - 00:03:31:00
where do cattle fit
00:03:31:00 - 00:03:32:13
to the climate systems
00:03:32:13 - 00:03:34:02
and what,
00:03:34:02 - 00:03:35:04
what role do they play
00:03:35:04 - 00:03:36:13
and thinking about
00:03:36:13 - 00:03:37:05
food systems
00:03:37:05 - 00:03:38:23
as a whole and so,
00:03:38:23 - 00:03:39:11
California,
00:03:39:11 - 00:03:39:21
of course,
00:03:39:21 - 00:03:41:22
has many different forces
00:03:41:22 - 00:03:43:16
that are all combined
00:03:43:16 - 00:03:45:02
in this nexus right here.
00:03:45:02 - 00:03:45:23
And so I wanted to,
00:03:45:23 - 00:03:46:23
to pursue
00:03:46:23 - 00:03:47:17
this pathway
00:03:47:17 - 00:03:48:12
and think about
00:03:48:12 - 00:03:48:20
what are
00:03:48:20 - 00:03:49:17
some real opportunities.
00:03:49:17 - 00:03:50:18
And this is
00:03:50:18 - 00:03:51:09
this field
00:03:51:09 - 00:03:52:15
is exponential growing.
00:03:52:15 - 00:03:53:07
And it's still going
00:03:53:07 - 00:03:53:21
to continue
00:03:53:21 - 00:03:55:00
that exponential
00:03:55:00 - 00:03:56:04
growth here going forward
00:03:56:04 - 00:03:57:05
in terms of
00:03:57:05 - 00:03:57:17
thinking about
00:03:57:17 - 00:03:58:10
how do we continue
00:03:58:10 - 00:03:59:16
to have animals
00:03:59:16 - 00:04:01:09
part of food system
00:04:01:09 - 00:04:02:22
sustainability solutions.
00:04:02:22 - 00:04:03:20
And speaking about that,
00:04:03:20 - 00:04:04:05
let's talk
00:04:04:05 - 00:04:05:11
about ruminant animals
00:04:05:11 - 00:04:06:10
and what makes them so
00:04:06:10 - 00:04:07:23
complex and unique.
00:04:07:23 - 00:04:09:02
And what is a ruminant animal
00:04:09:02 - 00:04:10:03
explain that to us
00:04:10:03 - 00:04:10:18
a little bit.
00:04:10:18 - 00:04:11:00
Yeah.
00:04:11:00 - 00:04:11:12
So ruminant
00:04:11:12 - 00:04:12:20
animals are animals
00:04:12:20 - 00:04:14:03
that have specific
00:04:14:03 - 00:04:15:20
four chambered stomachs.
00:04:15:20 - 00:04:16:17
So they've evolved
00:04:16:17 - 00:04:17:06
over thousands
00:04:17:06 - 00:04:18:19
of thousands of years.
00:04:18:19 - 00:04:19:07
And this isn't
00:04:19:07 - 00:04:20:09
not just include cattle
00:04:20:09 - 00:04:21:21
or goats or sheep
00:04:21:21 - 00:04:22:18
that we have, you know,
00:04:22:18 - 00:04:23:20
on, farms
00:04:23:20 - 00:04:24:13
here in California
00:04:24:13 - 00:04:25:20
across the US.
00:04:25:20 - 00:04:27:01
But this also includes
00:04:27:01 - 00:04:28:04
the deer,
00:04:28:04 - 00:04:29:03
the bison,
00:04:29:03 - 00:04:31:04
the wild animals, too.
00:04:31:04 - 00:04:31:13
In order
00:04:31:13 - 00:04:33:10
for them to predominantly,
00:04:33:10 - 00:04:34:12
consume their diets
00:04:34:12 - 00:04:35:09
that are high in fiber
00:04:35:09 - 00:04:36:12
and things that humans
00:04:36:12 - 00:04:38:01
can't consume.
00:04:38:01 - 00:04:38:18
They utilize
00:04:38:18 - 00:04:39:11
this different
00:04:39:11 - 00:04:40:06
chambered stomach
00:04:40:06 - 00:04:40:14
to help
00:04:40:14 - 00:04:41:12
break down the fiber,
00:04:41:12 - 00:04:42:00
thanks to the help
00:04:42:00 - 00:04:42:12
of microbes
00:04:42:12 - 00:04:44:00
present in the gut.
00:04:44:00 - 00:04:44:14
And so in order
00:04:44:14 - 00:04:45:14
for them to consume feed,
00:04:45:14 - 00:04:48:13
of course, they have to,
00:04:48:15 - 00:04:50:01
have microbes to aid in
00:04:50:01 - 00:04:50:23
that digestion
00:04:50:23 - 00:04:52:06
of what they consume.
00:04:52:06 - 00:04:52:20
But then there's
00:04:52:20 - 00:04:53:18
also a trade off
00:04:53:18 - 00:04:55:11
in byproduct that
00:04:55:11 - 00:04:58:09
that methane is produced,
00:04:58:09 - 00:05:00:08
as a result of that
00:05:00:08 - 00:05:01:18
fermentation break down
00:05:01:18 - 00:05:02:15
process in the gut.
00:05:02:15 - 00:05:04:04
So, thinking about
00:05:04:04 - 00:05:05:11
how can you still provide
00:05:05:11 - 00:05:05:22
for animals
00:05:05:22 - 00:05:06:11
and think about
00:05:06:11 - 00:05:06:19
what they
00:05:06:19 - 00:05:07:18
need
00:05:07:20 - 00:05:09:00
and how they've evolved,
00:05:09:00 - 00:05:10:18
while also limiting
00:05:10:18 - 00:05:11:08
methane emissions
00:05:11:08 - 00:05:12:07
at the same time
00:05:12:07 - 00:05:14:07
Is this counterbalance,
00:05:14:07 - 00:05:15:14
place that we
00:05:15:14 - 00:05:16:12
we think about
00:05:16:12 - 00:05:17:12
what are opportunities
00:05:17:12 - 00:05:19:02
to find solutions
00:05:19:02 - 00:05:19:21
that
00:05:19:21 - 00:05:21:09
maximize animal health
00:05:21:09 - 00:05:22:10
and what they've evolved,
00:05:22:10 - 00:05:23:11
to consume.
00:05:23:11 - 00:05:24:02
But also,
00:05:24:02 - 00:05:24:13
how can we
00:05:24:13 - 00:05:25:06
essentially limit
00:05:25:06 - 00:05:27:00
or reduce
00:05:27:00 - 00:05:28:04
those methane emissions
00:05:28:04 - 00:05:28:20
produced that way
00:05:28:20 - 00:05:29:17
as well?
00:05:29:17 - 00:05:30:08
And one of those
00:05:30:08 - 00:05:31:12
possible solutions
00:05:31:12 - 00:05:32:16
are feed additives
00:05:32:16 - 00:05:33:07
And that's what you're
00:05:33:07 - 00:05:33:18
working on.
00:05:33:18 - 00:05:34:17
Explain your research
00:05:34:17 - 00:05:35:15
a little bit to us.
00:05:35:15 - 00:05:36:20
Yeah, so feed additives.
00:05:36:20 - 00:05:37:08
You know, I love
00:05:37:08 - 00:05:39:09
to use the analogy
00:05:39:09 - 00:05:40:09
of how we
00:05:40:09 - 00:05:41:00
where we feed
00:05:41:00 - 00:05:41:08
animals
00:05:41:08 - 00:05:42:12
is basically a casserole.
00:05:42:12 - 00:05:43:00
So we take
00:05:43:00 - 00:05:43:19
everything together,
00:05:43:19 - 00:05:44:12
we take the haze,
00:05:44:12 - 00:05:45:18
we take the byproducts,
00:05:45:18 - 00:05:46:08
and we mix them
00:05:46:08 - 00:05:46:21
all together
00:05:46:21 - 00:05:47:15
so that, you know,
00:05:47:15 - 00:05:47:20
when you're
00:05:47:20 - 00:05:49:03
taking a scoop of
00:05:49:03 - 00:05:49:18
that casserole,
00:05:49:18 - 00:05:50:05
you're not just
00:05:50:05 - 00:05:51:09
getting the,
00:05:51:09 - 00:05:52:19
the pasta
00:05:52:19 - 00:05:53:07
the noodles
00:05:53:07 - 00:05:53:19
or the sauce.
00:05:53:19 - 00:05:54:11
You're getting everything
00:05:54:11 - 00:05:55:20
involved in that.
00:05:55:20 - 00:05:56:10
The additives, it's
00:05:56:10 - 00:05:56:19
just like
00:05:56:19 - 00:05:57:16
the small spices
00:05:57:16 - 00:05:58:04
that you add on
00:05:58:04 - 00:05:58:19
on top of it
00:05:58:19 - 00:05:59:04
before you
00:05:59:04 - 00:05:59:18
put it in the oven.
00:05:59:18 - 00:06:00:16
There.
00:06:00:16 - 00:06:01:00
So these are
00:06:01:00 - 00:06:02:14
small, components
00:06:02:14 - 00:06:03:07
that have the ability
00:06:03:07 - 00:06:04:18
to make a big impact
00:06:04:18 - 00:06:05:13
on emissions
00:06:05:13 - 00:06:06:17
because they can do
00:06:06:17 - 00:06:07:06
two things.
00:06:07:06 - 00:06:07:22
They can do one,
00:06:07:22 - 00:06:09:02
they can inhibit
00:06:09:02 - 00:06:10:00
the pathway
00:06:10:00 - 00:06:10:17
or the enzymes
00:06:10:17 - 00:06:11:08
that are responsible
00:06:11:08 - 00:06:12:18
for methane formation
00:06:12:18 - 00:06:13:15
or they can make it
00:06:13:15 - 00:06:14:16
less favorable to form
00:06:14:16 - 00:06:15:03
methane in the
00:06:15:03 - 00:06:16:08
first place.
00:06:16:08 - 00:06:17:05
Two classifications.
00:06:17:05 - 00:06:18:01
The first one there
00:06:18:01 - 00:06:18:15
that I talked about
00:06:18:15 - 00:06:19:09
be inhibitors,
00:06:19:09 - 00:06:20:03
the second one will be
00:06:20:03 - 00:06:21:10
rumen modifiers there
00:06:21:10 - 00:06:22:07
that in small amounts
00:06:22:07 - 00:06:23:16
can have impacts anywhere
00:06:23:16 - 00:06:24:15
from about 10
00:06:24:15 - 00:06:26:05
to 30% reductions.
00:06:26:05 - 00:06:28:02
Wow, wow.
00:06:28:02 - 00:06:28:22
So tell us a little bit
00:06:28:22 - 00:06:29:18
about the research study
00:06:29:18 - 00:06:30:07
that you've been
00:06:30:07 - 00:06:30:21
a part of here,
00:06:30:21 - 00:06:31:22
how big it is.
00:06:31:22 - 00:06:32:16
And just
00:06:32:16 - 00:06:33:06
I mean, just tell us
00:06:33:06 - 00:06:33:20
a little bit about it
00:06:33:20 - 00:06:34:15
because it is amazing.
00:06:34:15 - 00:06:34:22
Yeah.
00:06:34:22 - 00:06:35:22
So it's been going on
00:06:35:22 - 00:06:39:02
for almost
00:06:39:04 - 00:06:39:20
almost a year.
00:06:39:20 - 00:06:40:03
We're going to
00:06:40:03 - 00:06:40:14
approaching that
00:06:40:14 - 00:06:41:02
at this point
00:06:41:02 - 00:06:41:16
and still not
00:06:41:16 - 00:06:42:18
even halfway over.
00:06:42:18 - 00:06:43:18
So it is
00:06:43:18 - 00:06:45:14
it's a long haul.
00:06:45:14 - 00:06:46:16
Coming here.
00:06:46:16 - 00:06:47:13
at Davis,
00:06:47:13 - 00:06:48:01
we’re working with
00:06:48:01 - 00:06:49:18
the molecule,
00:06:49:18 - 00:06:51:14
3-Nitrooxypropanol
00:06:51:14 - 00:06:52:13
or how we're going to
00:06:52:13 - 00:06:53:07
to refer it on
00:06:53:07 - 00:06:53:19
out here,
00:06:53:19 - 00:06:54:20
just say 3-NOP
00:06:54:20 - 00:06:56:02
because that's,
00:06:56:02 - 00:06:56:18
a little bit easier
00:06:56:18 - 00:06:57:08
for on the
00:06:57:08 - 00:06:59:02
on the eyes and ears.
00:06:59:02 - 00:07:00:07
3-NOP is a product
00:07:00:07 - 00:07:00:21
that's coming
00:07:00:21 - 00:07:01:07
commercially
00:07:01:07 - 00:07:02:03
available here
00:07:02:03 - 00:07:02:22
in California, though
00:07:02:22 - 00:07:03:07
different
00:07:03:07 - 00:07:04:04
different companies
00:07:04:04 - 00:07:04:17
in many
00:07:04:17 - 00:07:05:07
different countries
00:07:05:07 - 00:07:05:18
around the world.
00:07:05:18 - 00:07:07:10
But it's been,
00:07:07:12 - 00:07:08:07
approved by different
00:07:08:07 - 00:07:09:15
regulatory groups.
00:07:09:15 - 00:07:10:18
And,
00:07:10:18 - 00:07:11:13
it has the opportunity
00:07:11:13 - 00:07:11:23
to reduce
00:07:11:23 - 00:07:12:16
methane emissions
00:07:12:16 - 00:07:13:00
by anywhere
00:07:13:00 - 00:07:14:07
from about 20 to 30%,
00:07:14:07 - 00:07:15:11
depending on the study,
00:07:15:11 - 00:07:16:08
depending on
00:07:16:08 - 00:07:16:23
what what
00:07:16:23 - 00:07:18:09
animals are fed.
00:07:18:09 - 00:07:18:22
Because of course
00:07:18:22 - 00:07:19:14
there's interactions,
00:07:19:14 - 00:07:20:02
of course, when
00:07:20:02 - 00:07:21:01
the animals eat
00:07:21:01 - 00:07:21:19
to how much methane
00:07:21:19 - 00:07:22:07
they produce
00:07:22:07 - 00:07:23:02
and how well this
00:07:23:02 - 00:07:24:18
3-NOP works.
00:07:24:18 - 00:07:25:01
Well,
00:07:25:01 - 00:07:25:21
our goal for this
00:07:25:21 - 00:07:28:09
project is is looking at
00:07:28:09 - 00:07:29:09
you know,
00:07:29:09 - 00:07:30:08
I talked about animals
00:07:30:08 - 00:07:30:20
evolving
00:07:30:20 - 00:07:31:19
for a ruminant stomach
00:07:31:19 - 00:07:34:06
over thousands of years.
00:07:34:06 - 00:07:36:05
But these,
00:07:36:05 - 00:07:37:08
digestive systems of cows
00:07:37:08 - 00:07:38:18
have never seen something
00:07:38:18 - 00:07:39:20
that would inhibit
00:07:39:20 - 00:07:41:05
methane production.
00:07:41:05 - 00:07:42:13
For this period of time.
00:07:42:13 - 00:07:43:15
So could
00:07:43:15 - 00:07:45:01
the microbes in the gut
00:07:45:01 - 00:07:46:18
essentially work around
00:07:46:18 - 00:07:49:03
these stressors?
00:07:49:03 - 00:07:49:18
Because that's essential.
00:07:49:18 - 00:07:50:04
what they are
00:07:50:04 - 00:07:52:05
They're disrupting what,
00:07:52:05 - 00:07:52:20
what would have
00:07:52:20 - 00:07:54:02
historically been a
00:07:54:02 - 00:07:54:19
natural part
00:07:54:19 - 00:07:56:09
of digestion there.
00:07:56:09 - 00:07:57:05
And so
00:07:57:05 - 00:07:57:22
we're looking
00:07:57:22 - 00:07:58:15
interested to see
00:07:58:15 - 00:07:59:11
are emission reductions
00:07:59:11 - 00:08:00:07
the same on day
00:08:00:07 - 00:08:01:20
one as they are on day
00:08:01:20 - 00:08:03:11
500 plus.
00:08:03:11 - 00:08:04:18
Is the real interest here
00:08:04:18 - 00:08:05:18
because there's
00:08:05:18 - 00:08:06:14
there's folks
00:08:06:14 - 00:08:07:09
in the dairy industry,
00:08:07:09 - 00:08:08:01
there's folks
00:08:08:01 - 00:08:09:14
who are milk buyers
00:08:09:14 - 00:08:10:00
and trying
00:08:10:00 - 00:08:11:19
to figure out their own,
00:08:11:19 - 00:08:13:03
solutions for their own
00:08:13:03 - 00:08:14:00
milk supply chain
00:08:14:00 - 00:08:15:19
and carbon associations
00:08:15:19 - 00:08:18:05
to figure out,
00:08:18:07 - 00:08:19:05
can we utilize
00:08:19:05 - 00:08:20:02
this feed additive
00:08:20:02 - 00:08:22:06
as a solution today,
00:08:22:06 - 00:08:25:00
next year, next decade?
00:08:25:00 - 00:08:25:20
As we think about
00:08:25:20 - 00:08:26:14
trying to
00:08:26:14 - 00:08:28:04
permanently reduce
00:08:28:04 - 00:08:29:10
methane emissions
00:08:29:10 - 00:08:30:05
long term here
00:08:30:05 - 00:08:30:22
in California.
00:08:30:22 - 00:08:31:19
Wow.
00:08:31:19 - 00:08:32:16
So how big is this?
00:08:32:16 - 00:08:32:21
I mean,
00:08:32:21 - 00:08:33:14
how many cows
00:08:33:14 - 00:08:34:11
can we talk about that?
00:08:34:11 - 00:08:34:20
Yeah.
00:08:34:20 - 00:08:35:14
And the scope
00:08:35:14 - 00:08:36:10
and size and scale.
00:08:36:10 - 00:08:38:02
So you know, right now
00:08:38:02 - 00:08:40:04
we currently have 66
00:08:40:04 - 00:08:41:18
cows on study.
00:08:41:18 - 00:08:42:10
When you look at the
00:08:42:10 - 00:08:43:14
UC Davis dairy,
00:08:43:14 - 00:08:44:19
that's about two thirds
00:08:44:19 - 00:08:45:06
the animals.
00:08:45:06 - 00:08:46:00
So
00:08:46:00 - 00:08:46:21
so we're basically feeding
00:08:46:21 - 00:08:48:10
the entire dairy of cows
00:08:48:10 - 00:08:49:08
every single
00:08:49:08 - 00:08:50:04
morning in the night,
00:08:50:04 - 00:08:51:09
which is a lot of work.
00:08:51:09 - 00:08:51:19
And there's a whole
00:08:51:19 - 00:08:52:04
bunch of people
00:08:52:04 - 00:08:52:15
that are involved
00:08:52:15 - 00:08:53:10
in making this happen
00:08:53:10 - 00:08:54:22
from other grad students,
00:08:54:22 - 00:08:55:18
junior specialists,
00:08:55:18 - 00:08:57:23
postdocs, undergrads,
00:08:57:23 - 00:08:58:14
who are all putting
00:08:58:14 - 00:08:59:09
in a lot of hours
00:08:59:09 - 00:09:00:01
and making
00:09:00:01 - 00:09:01:03
this all happen every
00:09:01:03 - 00:09:02:23
single day of the year.
00:09:03:01 - 00:09:03:21
And, you know,
00:09:03:21 - 00:09:05:12
it's going to be
00:09:05:12 - 00:09:06:15
have a big celebration
00:09:06:15 - 00:09:07:03
for sure.
00:09:07:03 - 00:09:07:21
When it's all
00:09:07:21 - 00:09:09:08
going to be done
00:09:09:08 - 00:09:10:02
when they
00:09:10:02 - 00:09:10:16
when we finally
00:09:10:16 - 00:09:11:06
figure out that,
00:09:11:06 - 00:09:11:17
that final,
00:09:11:17 - 00:09:12:10
they’d have to pencil
00:09:12:10 - 00:09:14:16
that in and figure out,
00:09:14:16 - 00:09:15:08
where, what
00:09:15:08 - 00:09:16:00
what celebration
00:09:16:00 - 00:09:16:18
we're going to do then.
00:09:16:18 - 00:09:18:07
But, yeah,
00:09:18:07 - 00:09:19:01
it's a whole lot
00:09:19:01 - 00:09:19:21
of combinations.
00:09:19:21 - 00:09:21:02
And they’re so different
00:09:21:02 - 00:09:21:20
many offsets
00:09:21:20 - 00:09:22:13
that we're looking at.
00:09:22:13 - 00:09:24:13
How does this impact,
00:09:24:13 - 00:09:25:05
the whole animal.
00:09:25:05 - 00:09:25:20
So how does it
00:09:25:20 - 00:09:27:10
impacts, emissions?
00:09:27:10 - 00:09:28:11
How does it impact animal
00:09:28:11 - 00:09:28:21
health,
00:09:28:21 - 00:09:30:23
animal production?
00:09:30:23 - 00:09:32:06
The microbiome
00:09:32:06 - 00:09:33:20
are also other,
00:09:33:20 - 00:09:34:04
pieces
00:09:34:04 - 00:09:35:06
that we're interested in.
00:09:35:06 - 00:09:35:23
So there's,
00:09:35:23 - 00:09:36:11
there's many
00:09:36:11 - 00:09:38:10
different components.
00:09:38:10 - 00:09:39:17
Because who knows
00:09:39:17 - 00:09:40:15
if and when this,
00:09:40:15 - 00:09:41:00
this study
00:09:41:00 - 00:09:41:16
will be replicated
00:09:41:16 - 00:09:43:08
because, you know,
00:09:43:08 - 00:09:44:01
we may have,
00:09:44:01 - 00:09:45:00
have done all this work
00:09:45:00 - 00:09:45:12
and been like,
00:09:45:12 - 00:09:46:05
that's a lot of work.
00:09:46:05 - 00:09:46:20
And maybe
00:09:46:20 - 00:09:47:18
no one else for,
00:09:47:18 - 00:09:48:09
for any other piece
00:09:48:09 - 00:09:49:03
is going to want
00:09:49:03 - 00:09:49:20
to pursue that.
00:09:49:20 - 00:09:51:04
So it's
00:09:51:04 - 00:09:52:05
certainly exciting piece
00:09:52:05 - 00:09:53:09
to be part of helping
00:09:53:09 - 00:09:54:21
set up and play a role
00:09:54:21 - 00:09:56:04
in taking part
00:09:56:04 - 00:09:58:03
in this at this time.
00:09:58:05 - 00:10:00:17
And excited to see,
00:10:00:17 - 00:10:01:16
when those results
00:10:01:16 - 00:10:02:11
come out, you know, no
00:10:02:11 - 00:10:02:21
guarantee
00:10:02:21 - 00:10:03:14
when that's going to be,
00:10:03:14 - 00:10:05:13
but it's going to be
00:10:05:13 - 00:10:06:00
we're going to say
00:10:06:00 - 00:10:07:10
at least a few years
00:10:07:10 - 00:10:07:22
from now
00:10:07:22 - 00:10:08:14
until till
00:10:08:14 - 00:10:09:07
those conclusions
00:10:09:07 - 00:10:10:16
are brought together.
00:10:10:16 - 00:10:11:00
And you're
00:10:11:00 - 00:10:11:22
just logistically,
00:10:11:22 - 00:10:12:18
I mean, how
00:10:12:18 - 00:10:13:13
how long does it take
00:10:13:13 - 00:10:14:09
to get the cattle
00:10:14:09 - 00:10:15:09
kind of acclimated
00:10:15:09 - 00:10:16:12
to the feed additive?
00:10:16:12 - 00:10:17:04
How do you give them
00:10:17:04 - 00:10:17:21
the feed additive?
00:10:17:21 - 00:10:18:10
Tell us a little bit
00:10:18:10 - 00:10:19:21
about that process. Yes.
00:10:19:21 - 00:10:21:07
So our feed additive
00:10:21:07 - 00:10:22:23
that we're utilizing,
00:10:22:23 - 00:10:24:21
we are
00:10:24:21 - 00:10:25:16
it is a very
00:10:25:16 - 00:10:26:04
small amount,
00:10:26:04 - 00:10:26:11
you know,
00:10:26:11 - 00:10:27:10
I could hold in my hand
00:10:27:10 - 00:10:28:03
right here
00:10:28:03 - 00:10:29:07
how much each animal
00:10:29:07 - 00:10:30:16
is consuming per day.
00:10:30:16 - 00:10:32:06
So we think
00:10:32:06 - 00:10:33:00
about an animal
00:10:33:00 - 00:10:33:14
and I want to just
00:10:33:14 - 00:10:34:08
point out that
00:10:34:08 - 00:10:36:02
an average for,
00:10:36:02 - 00:10:36:15
for cows,
00:10:36:15 - 00:10:37:03
they're consuming
00:10:37:03 - 00:10:38:06
anywhere from 100 to
00:10:38:06 - 00:10:39:01
110 pounds
00:10:39:01 - 00:10:40:17
of feed per day.
00:10:40:19 - 00:10:41:18
And so if I put
00:10:41:18 - 00:10:43:08
what's here in my hand,
00:10:43:08 - 00:10:44:09
you know, across
00:10:44:09 - 00:10:45:07
all that feed,
00:10:45:07 - 00:10:47:06
it's pretty.
00:10:47:06 - 00:10:49:03
Pretty,
00:10:49:03 - 00:10:50:02
hard to,
00:10:50:02 - 00:10:50:22
to for them
00:10:50:22 - 00:10:52:00
to sniff it out or taste.
00:10:52:00 - 00:10:53:05
It's neutral.
00:10:53:05 - 00:10:54:13
Neutral,
00:10:54:13 - 00:10:55:07
neutral smelling.
00:10:55:07 - 00:10:56:12
So it's not
00:10:56:12 - 00:10:57:06
palatability
00:10:57:06 - 00:10:58:04
is not so much
00:10:58:04 - 00:10:59:11
an issue for that.
00:10:59:11 - 00:11:00:03
But what we do
00:11:00:03 - 00:11:00:22
to help mask
00:11:00:22 - 00:11:01:07
it in
00:11:01:07 - 00:11:02:16
is we add it to the feed
00:11:02:16 - 00:11:04:22
and let it mix through,
00:11:04:22 - 00:11:06:05
our casserole here.
00:11:06:05 - 00:11:06:20
So that way
00:11:06:20 - 00:11:08:04
that it gets blended up
00:11:08:04 - 00:11:09:17
and so that hopefully
00:11:09:17 - 00:11:10:23
our goal is that in each
00:11:10:23 - 00:11:11:13
and every bite
00:11:11:13 - 00:11:12:15
that cows are consuming,
00:11:12:15 - 00:11:13:06
that they're getting
00:11:13:06 - 00:11:13:18
a little bit
00:11:13:18 - 00:11:14:09
of the additive
00:11:14:09 - 00:11:14:21
as they go.
00:11:14:21 - 00:11:15:09
So that way
00:11:15:09 - 00:11:16:17
it's not a whole bunch
00:11:16:17 - 00:11:17:17
at one point in time.
00:11:17:17 - 00:11:18:08
It's not
00:11:18:08 - 00:11:19:05
there's none here.
00:11:19:05 - 00:11:20:11
So that way,
00:11:20:11 - 00:11:21:08
cows can can
00:11:21:08 - 00:11:22:05
continuously consume it
00:11:22:05 - 00:11:22:18
throughout the day
00:11:22:18 - 00:11:24:04
because this additive
00:11:24:04 - 00:11:25:20
has a limited lifespan
00:11:25:20 - 00:11:27:05
or active life
00:11:27:05 - 00:11:27:23
when it's present
00:11:27:23 - 00:11:28:16
in the gut.
00:11:28:16 - 00:11:29:06
So it has to be
00:11:29:06 - 00:11:29:19
continuously
00:11:29:19 - 00:11:30:23
consumed over time
00:11:30:23 - 00:11:31:06
in order
00:11:31:06 - 00:11:33:02
to have the same effect.
00:11:33:02 - 00:11:33:12
It'd be great
00:11:33:12 - 00:11:34:01
if we could feed it
00:11:34:01 - 00:11:34:14
once a day
00:11:34:14 - 00:11:35:12
and then
00:11:35:12 - 00:11:36:19
have a long term effect,
00:11:36:19 - 00:11:38:08
but unfortunately it's
00:11:38:08 - 00:11:39:02
it has to be
00:11:39:02 - 00:11:39:21
continuously fed
00:11:39:21 - 00:11:41:05
as it's broken down
00:11:41:05 - 00:11:42:07
and passed
00:11:42:07 - 00:11:42:19
out of the animal
00:11:42:19 - 00:11:43:11
at that point.
00:11:43:11 - 00:11:44:02
Make your life a
00:11:44:02 - 00:11:46:09
whole lot easier.
00:11:46:11 - 00:11:46:22
And then from
00:11:46:22 - 00:11:47:07
there, how do
00:11:47:07 - 00:11:47:16
you measure
00:11:47:16 - 00:11:48:07
the emissions?
00:11:48:07 - 00:11:48:23
How do you kind
00:11:48:23 - 00:11:49:10
of understand
00:11:49:10 - 00:11:50:18
if it's working or not?
00:11:50:18 - 00:11:51:01
Yeah.
00:11:51:01 - 00:11:51:23
So we have many
00:11:51:23 - 00:11:52:16
different techniques
00:11:52:16 - 00:11:53:14
that we could utilize
00:11:53:14 - 00:11:54:20
for how we,
00:11:54:20 - 00:11:56:21
accomplish this on farms.
00:11:56:21 - 00:11:57:05
You know,
00:11:57:05 - 00:11:58:06
I think everyone
00:11:58:06 - 00:11:59:05
is interested
00:11:59:05 - 00:12:00:05
and they're wondering,
00:12:00:05 - 00:12:00:18
especially
00:12:00:18 - 00:12:01:09
the undergrads,
00:12:01:09 - 00:12:01:22
when they first come
00:12:01:22 - 00:12:02:08
to the project
00:12:02:08 - 00:12:02:16
that they're like,
00:12:02:16 - 00:12:03:07
how do we actually
00:12:03:07 - 00:12:03:18
measure them?
00:12:03:18 - 00:12:04:02
They're thinking
00:12:04:02 - 00:12:05:01
that they have to chase
00:12:05:01 - 00:12:05:09
the animals
00:12:05:09 - 00:12:06:03
around with bags
00:12:06:03 - 00:12:07:12
or how do we
00:12:07:12 - 00:12:08:08
how do we capture
00:12:08:08 - 00:12:09:02
the emissions
00:12:09:02 - 00:12:09:13
at that point?
00:12:09:13 - 00:12:10:13
You know,
00:12:10:13 - 00:12:11:20
but we have these,
00:12:11:20 - 00:12:13:02
units that are called
00:12:13:02 - 00:12:14:12
greenfeeds.
00:12:14:12 - 00:12:15:06
And the closest thing
00:12:15:06 - 00:12:15:20
that I can say
00:12:15:20 - 00:12:16:13
is that they're basically
00:12:16:13 - 00:12:18:11
breathalyzers for cows
00:12:18:11 - 00:12:20:08
and that the cows are,
00:12:20:08 - 00:12:21:08
individually trained.
00:12:21:08 - 00:12:22:00
Some are easier
00:12:22:00 - 00:12:23:04
than others,
00:12:23:04 - 00:12:24:19
to walk up to a machine,
00:12:24:19 - 00:12:25:12
and they have
00:12:25:12 - 00:12:26:12
tags in each
00:12:26:12 - 00:12:27:12
one of their ears
00:12:27:12 - 00:12:29:11
that says that this cow
00:12:29:11 - 00:12:31:12
cow a b
00:12:31:12 - 00:12:31:18
or call
00:12:31:18 - 00:12:32:20
Abigail and bessy
00:12:32:20 - 00:12:34:12
for that reason,
00:12:34:12 - 00:12:35:08
they come up to
00:12:35:08 - 00:12:36:10
to the machine
00:12:36:10 - 00:12:37:06
and then it says,
00:12:37:06 - 00:12:38:01
Abigail's here.
00:12:38:01 - 00:12:38:18
So then it drops
00:12:38:18 - 00:12:39:15
a little bit of feed
00:12:39:15 - 00:12:40:21
for them to consume.
00:12:40:21 - 00:12:41:17
And while they're eating,
00:12:41:17 - 00:12:42:04
they're
00:12:42:04 - 00:12:43:00
they're constantly
00:12:43:00 - 00:12:43:23
belching and burping
00:12:43:23 - 00:12:44:15
methane throughout
00:12:44:15 - 00:12:45:13
the day.
00:12:45:13 - 00:12:46:09
And we're also interested
00:12:46:09 - 00:12:47:06
in other gases
00:12:47:06 - 00:12:48:15
such as hydrogen, oxygen,
00:12:48:15 - 00:12:50:22
carbon dioxide, as those
00:12:50:22 - 00:12:52:22
can influence metabolism
00:12:52:22 - 00:12:54:02
and give us insights into
00:12:54:02 - 00:12:54:14
what is happening
00:12:54:14 - 00:12:55:17
at the animal level.
00:12:55:17 - 00:12:58:18
So understanding,
00:12:58:20 - 00:12:59:20
how long
00:12:59:20 - 00:13:00:11
animals are there
00:13:00:11 - 00:13:01:05
Theyr’e usually there
00:13:01:05 - 00:13:02:01
at the greenfeed
00:13:02:01 - 00:13:04:09
for about 2 to 3 minutes.
00:13:04:09 - 00:13:05:12
Sometimes some animals
00:13:05:12 - 00:13:06:11
stay longer up
00:13:06:11 - 00:13:08:06
to 5 minutes.
00:13:08:06 - 00:13:09:07
And we take those samples
00:13:09:07 - 00:13:09:21
at different time
00:13:09:21 - 00:13:11:04
points today.
00:13:11:04 - 00:13:11:20
Because of course,
00:13:11:20 - 00:13:12:04
like you
00:13:12:04 - 00:13:12:22
and I, you know,
00:13:12:22 - 00:13:14:14
we consume meals
00:13:14:14 - 00:13:14:22
at different
00:13:14:22 - 00:13:16:07
times of day.
00:13:16:07 - 00:13:17:07
Sometimes we're sleeping.
00:13:17:07 - 00:13:18:08
So you can imagine cows
00:13:18:08 - 00:13:19:15
don't sleep like us,
00:13:19:15 - 00:13:20:16
but they're not eating
00:13:20:16 - 00:13:21:12
so much at night.
00:13:21:12 - 00:13:22:08
So their emissions
00:13:22:08 - 00:13:22:23
are lower
00:13:22:23 - 00:13:23:17
at that point of day.
00:13:23:17 - 00:13:24:18
Whereas after
00:13:24:18 - 00:13:25:20
they take their first big
00:13:25:20 - 00:13:26:14
morning meal
00:13:26:14 - 00:13:27:08
and then emissions
00:13:27:08 - 00:13:27:19
are going to peak.
00:13:27:19 - 00:13:28:07
So interested
00:13:28:07 - 00:13:28:19
in looking at
00:13:28:19 - 00:13:29:14
how do emissions
00:13:29:14 - 00:13:30:19
vary throughout the day.
00:13:30:19 - 00:13:31:15
So they try to come
00:13:31:15 - 00:13:31:22
and go
00:13:31:22 - 00:13:33:03
and get little treats.
00:13:33:03 - 00:13:34:10
Some can go five
00:13:34:10 - 00:13:35:08
six times a day,
00:13:35:08 - 00:13:36:00
which means
00:13:36:00 - 00:13:37:02
they're trying
00:13:37:02 - 00:13:37:09
to check
00:13:37:09 - 00:13:38:03
the candy machine
00:13:38:03 - 00:13:38:23
to see when it's,
00:13:38:23 - 00:13:40:20
whenever it's open.
00:13:40:20 - 00:13:42:22
To get this piece.
00:13:42:22 - 00:13:43:21
So they do not know that
00:13:43:21 - 00:13:44:10
their emissions
00:13:44:10 - 00:13:45:08
have been sampled.
00:13:45:08 - 00:13:45:20
They just think
00:13:45:20 - 00:13:47:04
they're getting a treat.
00:13:47:04 - 00:13:48:06
Which makes it easier,
00:13:48:06 - 00:13:49:14
easier on us to,
00:13:49:14 - 00:13:50:12
to get the data.
00:13:50:12 - 00:13:51:20
Just going to coax them
00:13:51:20 - 00:13:52:15
at first and learn
00:13:52:15 - 00:13:54:09
how to use the machine
00:13:54:09 - 00:13:55:02
and overall
00:13:55:02 - 00:13:55:17
feed additives.
00:13:55:17 - 00:13:56:05
They hold a lot
00:13:56:05 - 00:13:56:20
of promise.
00:13:56:20 - 00:13:57:05
Tell us
00:13:57:05 - 00:13:57:18
just a little bit
00:13:57:18 - 00:13:58:12
about that
00:13:58:12 - 00:13:59:21
and why
00:13:59:21 - 00:14:00:22
they hold so much promise
00:14:00:22 - 00:14:02:16
in mitigating methane.
00:14:02:16 - 00:14:03:00
Yeah.
00:14:03:00 - 00:14:03:23
So you know,
00:14:03:23 - 00:14:04:17
when thinking about,
00:14:04:17 - 00:14:06:12
you know, methane
00:14:06:12 - 00:14:07:12
mitigation, you know,
00:14:07:12 - 00:14:08:16
it's a it's
00:14:08:16 - 00:14:10:14
an up and coming,
00:14:10:16 - 00:14:11:11
area and topic.
00:14:11:11 - 00:14:12:22
And I think,
00:14:12:22 - 00:14:13:16
many countries around
00:14:13:16 - 00:14:13:21
the world
00:14:13:21 - 00:14:14:08
are figuring out
00:14:14:08 - 00:14:15:02
how to do it
00:14:15:02 - 00:14:16:08
because we have so many,
00:14:16:08 - 00:14:17:10
you know,
00:14:17:10 - 00:14:19:23
individual units to
00:14:19:23 - 00:14:21:13
to figure out,
00:14:21:13 - 00:14:22:00
and utilize.
00:14:22:00 - 00:14:23:10
And they talk about the
00:14:23:10 - 00:14:24:01
the downside of
00:14:24:01 - 00:14:24:10
that is
00:14:24:10 - 00:14:24:23
they have to be fed
00:14:24:23 - 00:14:25:21
every day.
00:14:25:21 - 00:14:26:10
But the big
00:14:26:10 - 00:14:27:04
benefit of them
00:14:27:04 - 00:14:28:04
is that
00:14:28:04 - 00:14:29:06
it's ongoing
00:14:29:06 - 00:14:29:23
with the practice
00:14:29:23 - 00:14:31:07
that producers
00:14:31:07 - 00:14:32:16
are already utilizing.
00:14:32:16 - 00:14:33:16
You know, in terms of
00:14:33:16 - 00:14:34:05
we already
00:14:34:05 - 00:14:35:03
utilize additives
00:14:35:03 - 00:14:35:16
that can help
00:14:35:16 - 00:14:36:17
with digestion.
00:14:36:17 - 00:14:38:14
we utilize additives
00:14:38:14 - 00:14:39:01
that can help
00:14:39:01 - 00:14:40:06
with animal health.
00:14:40:06 - 00:14:41:05
Think about
00:14:41:05 - 00:14:42:12
probiotics, prebiotics,
00:14:42:12 - 00:14:43:00
you know, that
00:14:43:00 - 00:14:43:18
we use for humans.
00:14:43:18 - 00:14:44:20
We also use for
00:14:44:20 - 00:14:46:03
for animals as well.
00:14:46:03 - 00:14:49:23
So utilizing a solution
00:14:49:23 - 00:14:51:02
that can one already
00:14:51:02 - 00:14:52:11
be utilized by producers.
00:14:52:11 - 00:14:53:01
You know, it's something
00:14:53:01 - 00:14:53:22
that you just readily
00:14:53:22 - 00:14:54:15
add to the feed
00:14:54:15 - 00:14:57:01
based on what is,
00:14:57:03 - 00:14:57:17
currently already
00:14:57:17 - 00:14:58:22
being done.
00:14:58:22 - 00:14:59:07
Can easily
00:14:59:07 - 00:15:00:10
be applied to that.
00:15:00:10 - 00:15:03:00
And so thinking about
00:15:03:00 - 00:15:03:17
there are a little bit
00:15:03:17 - 00:15:04:09
of technicalities
00:15:04:09 - 00:15:04:20
in terms of
00:15:04:20 - 00:15:05:08
how do you get
00:15:05:08 - 00:15:06:05
the right dosage
00:15:06:05 - 00:15:06:16
and how do you
00:15:06:16 - 00:15:07:20
get the right
00:15:07:20 - 00:15:09:02
consistency on farm
00:15:09:02 - 00:15:09:15
over time.
00:15:09:15 - 00:15:10:22
Because methane, it's
00:15:10:22 - 00:15:11:10
not something
00:15:11:10 - 00:15:12:07
you can easily measure,
00:15:12:07 - 00:15:14:10
like milk or growth
00:15:14:10 - 00:15:16:00
or production.
00:15:16:00 - 00:15:17:05
So thinking about
00:15:17:05 - 00:15:17:23
how do you
00:15:17:23 - 00:15:18:16
standardize that
00:15:18:16 - 00:15:19:12
and how do you
00:15:19:12 - 00:15:20:04
roll it out
00:15:20:04 - 00:15:20:19
has some certain
00:15:20:19 - 00:15:22:02
complexities to it.
00:15:22:02 - 00:15:22:13
But you know,
00:15:22:13 - 00:15:23:21
I think about today
00:15:23:21 - 00:15:25:08
we can feed cows down
00:15:25:08 - 00:15:26:09
to the individual
00:15:26:09 - 00:15:27:07
level of nutrition,
00:15:27:07 - 00:15:27:22
as I think I did
00:15:27:22 - 00:15:28:12
on the podcast
00:15:28:12 - 00:15:29:16
I've talked about here.
00:15:29:16 - 00:15:30:23
You know, I think we're
00:15:30:23 - 00:15:31:20
we are
00:15:31:20 - 00:15:32:22
not in the same front
00:15:32:22 - 00:15:33:14
on methane
00:15:33:14 - 00:15:34:11
environmental things,
00:15:34:11 - 00:15:35:11
but certainly with,
00:15:35:11 - 00:15:36:18
with more time and,
00:15:36:18 - 00:15:38:05
and
00:15:38:05 - 00:15:39:07
technology advances.
00:15:39:07 - 00:15:39:22
I think, you know, we'll
00:15:39:22 - 00:15:40:14
certainly be able
00:15:40:14 - 00:15:41:23
to say one day
00:15:41:23 - 00:15:44:07
that you can be checking
00:15:44:07 - 00:15:44:23
how much methane
00:15:44:23 - 00:15:45:07
or my cow
00:15:45:07 - 00:15:46:01
is producing today
00:15:46:01 - 00:15:46:13
based on it,
00:15:46:13 - 00:15:47:02
and it can be
00:15:47:02 - 00:15:47:12
a number
00:15:47:12 - 00:15:47:22
that's,
00:15:47:22 - 00:15:48:16
you know, up there
00:15:48:16 - 00:15:49:07
and synonymous
00:15:49:07 - 00:15:50:01
with what was milk
00:15:50:01 - 00:15:51:14
production today, as well
00:15:51:14 - 00:15:52:01
as potential
00:15:52:01 - 00:15:53:00
more real world
00:15:53:00 - 00:15:53:11
impact,
00:15:53:11 - 00:15:54:02
which we talk a lot
00:15:54:02 - 00:15:54:14
about at the
00:15:54:14 - 00:15:56:03
Clear Center.
00:15:56:03 - 00:15:56:11
And speaking
00:15:56:11 - 00:15:57:20
of real world impact,
00:15:57:20 - 00:15:58:17
tell me a little bit
00:15:58:17 - 00:15:59:23
about the hours
00:15:59:23 - 00:16:00:09
that you put
00:16:00:09 - 00:16:01:12
this is a real world job
00:16:01:12 - 00:16:02:10
that these
00:16:02:10 - 00:16:05:00
researchers do out at,
00:16:05:02 - 00:16:06:09
the dairy and out at
00:16:06:09 - 00:16:07:16
the feedlot
00:16:07:16 - 00:16:08:09
when you were in the
00:16:08:09 - 00:16:09:09
heart of this study.
00:16:09:09 - 00:16:09:22
I mean, tell us
00:16:09:22 - 00:16:10:15
about the hours,
00:16:10:15 - 00:16:10:23
what time
00:16:10:23 - 00:16:11:11
you would get out
00:16:11:11 - 00:16:12:04
at the dairy,
00:16:12:04 - 00:16:13:01
what time you would
00:16:13:01 - 00:16:14:05
leave the dairy,
00:16:14:05 - 00:16:14:15
how many people
00:16:14:15 - 00:16:15:06
were working on
00:16:15:06 - 00:16:15:14
the study?
00:16:15:14 - 00:16:15:22
Just tell us
00:16:15:22 - 00:16:16:16
a little bit about that,
00:16:16:16 - 00:16:17:02
because I think
00:16:17:02 - 00:16:17:15
it's amazing.
00:16:17:15 - 00:16:19:05
I brag on you guys a lot
00:16:19:05 - 00:16:19:22
because when we're
00:16:19:22 - 00:16:20:17
having vacation
00:16:20:17 - 00:16:21:09
or we're
00:16:21:09 - 00:16:22:14
having a weekend,
00:16:22:14 - 00:16:23:02
you guys are
00:16:23:02 - 00:16:24:01
still working.
00:16:24:01 - 00:16:24:07
Yeah.
00:16:24:07 - 00:16:25:02
I mean,
00:16:25:02 - 00:16:25:17
there was
00:16:25:17 - 00:16:26:14
this period of time
00:16:26:14 - 00:16:28:07
where, you know, I didn't
00:16:28:07 - 00:16:29:17
I saw my house,
00:16:29:17 - 00:16:30:18
I saw the dairy farm,
00:16:30:18 - 00:16:31:09
and I saw
00:16:31:09 - 00:16:32:16
the lab here in Meyer
00:16:32:16 - 00:16:33:04
and the
00:16:33:04 - 00:16:33:17
maybe the grocery
00:16:33:17 - 00:16:34:04
store too.
00:16:34:04 - 00:16:35:04
That was the only
00:16:35:04 - 00:16:36:04
one that too.
00:16:36:04 - 00:16:37:13
but besides that,
00:16:37:13 - 00:16:37:21
you know,
00:16:37:21 - 00:16:38:16
every single morning,
00:16:38:16 - 00:16:39:07
it's not just me.
00:16:39:07 - 00:16:39:18
There's a lot
00:16:39:18 - 00:16:40:11
of other undergrads,
00:16:40:11 - 00:16:41:04
a lot of other folks
00:16:41:04 - 00:16:41:13
that are working
00:16:41:13 - 00:16:42:01
on the project
00:16:42:01 - 00:16:42:12
to make this
00:16:42:12 - 00:16:43:10
all happen now
00:16:43:10 - 00:16:44:15
and into the future.
00:16:44:15 - 00:16:46:18
But, when we start,
00:16:46:18 - 00:16:47:19
when they start milking
00:16:47:19 - 00:16:48:15
cows, each
00:16:48:15 - 00:16:50:12
morning at 4 a.m.
00:16:50:14 - 00:16:51:19
And cows
00:16:51:19 - 00:16:52:14
get milked twice a day,
00:16:52:14 - 00:16:53:10
so that's 4 a.m.
00:16:53:10 - 00:16:54:20
And 4 p.m.
00:16:54:20 - 00:16:55:06
And that can
00:16:55:06 - 00:16:55:22
last anywhere
00:16:55:22 - 00:16:58:09
from 3 to 4 hours,
00:16:58:09 - 00:16:59:07
to feed
00:16:59:07 - 00:17:00:03
every single animal.
00:17:00:03 - 00:17:01:04
Because we have several
00:17:01:04 - 00:17:01:23
different diets
00:17:01:23 - 00:17:02:18
across several
00:17:02:18 - 00:17:03:23
different points in time.
00:17:03:23 - 00:17:05:12
Plus we have to take
00:17:05:12 - 00:17:05:21
figure out
00:17:05:21 - 00:17:06:16
what they didn't eat
00:17:06:16 - 00:17:07:06
so we can figure out
00:17:07:06 - 00:17:08:03
how much to feed them
00:17:08:03 - 00:17:08:11
for the
00:17:08:11 - 00:17:09:17
for the following day.
00:17:09:17 - 00:17:10:21
And so it's,
00:17:10:21 - 00:17:11:10
it's this,
00:17:11:10 - 00:17:12:16
this very
00:17:12:16 - 00:17:13:08
intricate system,
00:17:13:08 - 00:17:13:15
you know,
00:17:13:15 - 00:17:14:17
I’d love to just show up
00:17:14:17 - 00:17:15:08
and just be able to
00:17:15:08 - 00:17:16:10
feed all the animals
00:17:16:10 - 00:17:18:06
one given feed
00:17:18:06 - 00:17:19:05
But we got to figure out,
00:17:19:05 - 00:17:19:22
you know, exactly
00:17:19:22 - 00:17:21:09
what to do,
00:17:21:09 - 00:17:22:05
how much they didn't eat,
00:17:22:05 - 00:17:22:14
how much they
00:17:22:14 - 00:17:23:05
are going to eat.
00:17:23:05 - 00:17:23:16
And that's all
00:17:23:16 - 00:17:24:18
part of these,
00:17:24:18 - 00:17:25:02
you know,
00:17:25:02 - 00:17:26:03
bigger
00:17:26:03 - 00:17:27:12
long term
00:17:27:12 - 00:17:28:04
study pieces
00:17:28:04 - 00:17:28:13
that are going
00:17:28:13 - 00:17:29:20
to come together.
00:17:29:20 - 00:17:30:11
Plus there's a lot
00:17:30:11 - 00:17:31:01
of different,
00:17:31:01 - 00:17:31:23
you know, maintenance
00:17:31:23 - 00:17:32:08
and cleaning
00:17:32:08 - 00:17:32:21
that all happens
00:17:32:21 - 00:17:33:13
in the background.
00:17:33:13 - 00:17:34:02
to all make
00:17:34:02 - 00:17:34:18
that possible.
00:17:34:18 - 00:17:36:17
So it's things that,
00:17:36:17 - 00:17:37:09
you know, happen
00:17:37:09 - 00:17:38:16
Monday through Friday,
00:17:38:16 - 00:17:40:00
Saturday and Sunday
00:17:40:00 - 00:17:41:10
and will be here
00:17:41:10 - 00:17:41:23
in the upcoming
00:17:41:23 - 00:17:43:19
holiday season as well,
00:17:43:19 - 00:17:44:22
to all make that happen.
00:17:44:22 - 00:17:46:05
So it's
00:17:46:05 - 00:17:46:20
it's certainly
00:17:46:20 - 00:17:47:15
a lot of work.
00:17:47:15 - 00:17:49:01
But you know,
00:17:49:01 - 00:17:50:04
people
00:17:50:04 - 00:17:51:14
like myself are in this
00:17:51:14 - 00:17:52:03
because it's
00:17:52:03 - 00:17:53:07
for the passion,
00:17:53:07 - 00:17:54:00
and what people
00:17:54:00 - 00:17:55:02
really enjoy to do
00:17:55:02 - 00:17:55:22
and being part of it.
00:17:55:22 - 00:17:56:14
And so,
00:17:56:14 - 00:17:58:05
you know, really
00:17:58:05 - 00:17:59:08
thankful to be a part
00:17:59:08 - 00:18:00:06
of these opportunities.
00:18:00:06 - 00:18:00:21
I didn't want to say that
00:18:00:21 - 00:18:01:09
I want to do it
00:18:01:09 - 00:18:02:06
every single day,
00:18:02:06 - 00:18:03:10
but, you know,
00:18:03:10 - 00:18:04:19
I like doing this
00:18:04:19 - 00:18:05:18
because this is what
00:18:05:18 - 00:18:06:06
we enjoy.
00:18:06:06 - 00:18:07:04
I want to be a part of.
00:18:07:04 - 00:18:07:18
And so that
00:18:07:18 - 00:18:08:14
that makes it,
00:18:08:14 - 00:18:09:06
you know,
00:18:09:06 - 00:18:10:08
something enjoyable
00:18:10:08 - 00:18:11:15
and it really makes
00:18:11:15 - 00:18:12:22
a PHD in Animal science.
00:18:12:22 - 00:18:15:09
Like it's certainly
00:18:15:09 - 00:18:16:00
we have skill
00:18:16:00 - 00:18:17:08
sets in a labs.
00:18:17:08 - 00:18:17:23
We have skill sets
00:18:17:23 - 00:18:18:14
in animals,
00:18:18:14 - 00:18:19:09
we have skill sets
00:18:19:09 - 00:18:20:09
in total,
00:18:20:09 - 00:18:21:04
total work ethic,
00:18:21:04 - 00:18:22:08
which gives us
00:18:22:08 - 00:18:23:15
so many skill sets to
00:18:23:15 - 00:18:24:05
to be set up
00:18:24:05 - 00:18:25:01
for the next thing here
00:18:25:01 - 00:18:25:23
and especially here,
00:18:25:23 - 00:18:26:04
as part
00:18:26:04 - 00:18:26:19
of the CLEAR Center
00:18:26:19 - 00:18:27:12
with the opportunities
00:18:27:12 - 00:18:27:18
that we get
00:18:27:18 - 00:18:28:11
to take part in
00:18:28:11 - 00:18:30:00
for research.
00:18:30:00 - 00:18:31:00
Well, being at a dairy
00:18:31:00 - 00:18:31:10
at 4 a.m.
00:18:31:10 - 00:18:31:23
might not be your
00:18:31:23 - 00:18:32:14
favorite memory,
00:18:32:14 - 00:18:33:04
but what do you
00:18:33:04 - 00:18:34:06
what's your
00:18:34:06 - 00:18:34:22
favorite memory
00:18:34:22 - 00:18:35:14
at UC Davis
00:18:35:14 - 00:18:35:22
or at the
00:18:35:22 - 00:18:36:18
clear Center, maybe.
00:18:36:18 - 00:18:37:19
What can you talk about?
00:18:37:19 - 00:18:38:13
A favorite memory
00:18:38:13 - 00:18:39:07
or a favorite event
00:18:39:07 - 00:18:41:02
you were part of or.
00:18:41:02 - 00:18:41:12
Yeah.
00:18:41:12 - 00:18:42:19
So, you know,
00:18:42:19 - 00:18:43:15
I've been having
00:18:43:15 - 00:18:44:20
a lot of unique
00:18:44:20 - 00:18:45:09
opportunities
00:18:45:09 - 00:18:46:03
and experiences here
00:18:46:03 - 00:18:46:10
as part of the
00:18:46:10 - 00:18:46:23
Career Center
00:18:46:23 - 00:18:47:15
that I know
00:18:47:15 - 00:18:48:19
that I would not have had
00:18:48:19 - 00:18:49:09
if I had gone to
00:18:49:09 - 00:18:51:02
another program.
00:18:51:04 - 00:18:51:15
But being
00:18:51:15 - 00:18:53:05
part of the clear center
00:18:53:05 - 00:18:54:09
and dr. Mitloehner’s
00:18:54:09 - 00:18:55:09
work
00:18:55:09 - 00:18:55:21
being able
00:18:55:21 - 00:18:56:10
to attend
00:18:56:10 - 00:18:57:10
the Sustainable Livestock
00:18:57:10 - 00:18:58:02
Transformation
00:18:58:02 - 00:18:59:17
Conference, at FAO
00:18:59:17 - 00:19:00:20
as being,
00:19:00:20 - 00:19:01:17
serving as a delegate
00:19:01:17 - 00:19:03:13
representing the U.S.
00:19:03:13 - 00:19:04:11
along there
00:19:04:11 - 00:19:05:06
with dr. Mitloehner
00:19:05:06 - 00:19:06:03
and being there in Rome
00:19:06:03 - 00:19:06:20
and hearing
00:19:06:20 - 00:19:07:16
like how
00:19:07:16 - 00:19:08:14
this collaboration
00:19:08:14 - 00:19:10:05
around methane emissions
00:19:10:05 - 00:19:10:17
and livestock
00:19:10:17 - 00:19:11:20
sustainability
00:19:11:20 - 00:19:12:21
is really evolving.
00:19:12:21 - 00:19:13:11
You know,
00:19:13:11 - 00:19:14:07
I think
00:19:14:07 - 00:19:15:09
Frank walks
00:19:15:09 - 00:19:16:14
around everywhere there
00:19:16:14 - 00:19:17:19
and everyone knows him.
00:19:17:19 - 00:19:19:15
And because of the
00:19:19:15 - 00:19:20:12
the conversation
00:19:20:12 - 00:19:21:21
that he's brought around
00:19:21:21 - 00:19:22:23
livestock sustainability.
00:19:22:23 - 00:19:23:19
And I think about
00:19:23:19 - 00:19:24:05
all these
00:19:24:05 - 00:19:24:18
different people
00:19:24:18 - 00:19:25:03
and all these
00:19:25:03 - 00:19:25:17
different countries
00:19:25:17 - 00:19:27:01
are working together.
00:19:27:01 - 00:19:28:01
And exciting to see
00:19:28:01 - 00:19:28:22
and thinking about
00:19:28:22 - 00:19:30:05
how much momentum
00:19:30:05 - 00:19:31:02
is out there right now
00:19:31:02 - 00:19:31:16
and how much
00:19:31:16 - 00:19:32:12
is coming together.
00:19:32:12 - 00:19:33:21
It was really eye opening
00:19:33:21 - 00:19:35:23
because we talk about,
00:19:35:23 - 00:19:36:13
opportunities
00:19:36:13 - 00:19:37:06
for solutions here
00:19:37:06 - 00:19:38:17
in the United States.
00:19:38:17 - 00:19:39:04
And that's not going
00:19:39:04 - 00:19:40:00
to work everywhere,
00:19:40:00 - 00:19:40:21
because not everywhere
00:19:40:21 - 00:19:42:18
has livestock systems
00:19:42:18 - 00:19:43:16
or things
00:19:43:16 - 00:19:44:09
of sustainability
00:19:44:09 - 00:19:45:17
in the same way,
00:19:45:17 - 00:19:46:16
as we do.
00:19:46:16 - 00:19:47:10
Plus,
00:19:47:10 - 00:19:47:20
you know,
00:19:47:20 - 00:19:48:14
majority of
00:19:48:14 - 00:19:50:01
the animals are
00:19:50:01 - 00:19:51:10
located elsewhere
00:19:51:10 - 00:19:53:01
all around the world.
00:19:53:01 - 00:19:53:17
And so it
00:19:53:17 - 00:19:54:10
just thinks about
00:19:54:10 - 00:19:55:02
how can we think
00:19:55:02 - 00:19:56:01
about solutions
00:19:56:01 - 00:19:58:04
that are not one work
00:19:58:04 - 00:19:59:08
here in the US or work
00:19:59:08 - 00:20:01:02
in other environments?
00:20:01:02 - 00:20:01:15
Because at the
00:20:01:15 - 00:20:02:15
end of the day,
00:20:02:15 - 00:20:03:10
we're
00:20:03:10 - 00:20:03:22
thinking about
00:20:03:22 - 00:20:04:21
how can we
00:20:04:21 - 00:20:06:01
improve nutrition,
00:20:06:01 - 00:20:07:20
how can we reduce
00:20:07:20 - 00:20:08:15
environmental impacts,
00:20:08:15 - 00:20:10:08
and how can we help with,
00:20:10:08 - 00:20:11:03
you know,
00:20:11:03 - 00:20:12:07
the billions of people
00:20:12:07 - 00:20:13:04
that are involved
00:20:13:04 - 00:20:15:01
in livestock systems
00:20:15:01 - 00:20:17:12
today, which is
00:20:17:12 - 00:20:20:04
makes this a consistent,
00:20:20:04 - 00:20:20:22
and challenging issue
00:20:20:22 - 00:20:22:13
that will continue to
00:20:22:13 - 00:20:23:01
think about
00:20:23:01 - 00:20:23:16
how do we create
00:20:23:16 - 00:20:24:05
more sustainable
00:20:24:05 - 00:20:24:19
food systems,
00:20:24:19 - 00:20:25:11
at least for,
00:20:25:11 - 00:20:26:11
for the rest of my,
00:20:26:11 - 00:20:28:13
my career here. So.
00:20:28:13 - 00:20:28:19
Well,
00:20:28:19 - 00:20:29:03
and speaking
00:20:29:03 - 00:20:29:15
of your career,
00:20:29:15 - 00:20:30:00
as we wrap
00:20:30:00 - 00:20:31:07
things up here, what
00:20:31:07 - 00:20:32:02
what are your goals
00:20:32:02 - 00:20:33:00
with your future,
00:20:33:00 - 00:20:34:01
with your research
00:20:34:01 - 00:20:34:17
or personally,
00:20:34:17 - 00:20:35:03
what do you want
00:20:35:03 - 00:20:36:11
to do from here on out?
00:20:36:11 - 00:20:36:20
Yeah, I know
00:20:36:20 - 00:20:37:06
that's all a
00:20:37:06 - 00:20:37:19
great question
00:20:37:19 - 00:20:38:06
to think about.
00:20:38:06 - 00:20:39:13
What comes next for me
00:20:39:13 - 00:20:39:20
here?
00:20:39:20 - 00:20:42:09
as of today's taping,
00:20:42:09 - 00:20:42:23
I have not
00:20:42:23 - 00:20:43:14
figured out what
00:20:43:14 - 00:20:44:13
what comes next for me
00:20:44:13 - 00:20:45:10
just yet.
00:20:45:10 - 00:20:48:01
But, you know what?
00:20:48:01 - 00:20:48:18
What I want
00:20:48:18 - 00:20:49:13
to be involved in
00:20:49:13 - 00:20:50:04
and what I want to take
00:20:50:04 - 00:20:50:14
part in
00:20:50:14 - 00:20:51:14
is thinking about
00:20:51:14 - 00:20:53:14
working with various
00:20:53:14 - 00:20:55:00
different food companies
00:20:55:00 - 00:20:55:17
at this point
00:20:55:17 - 00:20:56:03
and thinking
00:20:56:03 - 00:20:57:07
about understanding
00:20:57:07 - 00:20:58:22
and providing
00:20:58:22 - 00:20:59:16
technical expertise
00:20:59:16 - 00:21:00:04
and background
00:21:00:04 - 00:21:01:15
that I've been able to
00:21:01:15 - 00:21:02:08
accrue here
00:21:02:08 - 00:21:03:10
through the clear center
00:21:03:10 - 00:21:03:23
and thinking about
00:21:03:23 - 00:21:04:14
how do we
00:21:04:14 - 00:21:05:13
actually implement
00:21:05:13 - 00:21:06:07
these opportunities
00:21:06:07 - 00:21:06:20
on farms
00:21:06:20 - 00:21:07:11
that I've worked out.
00:21:07:11 - 00:21:08:10
So that's the feed additives,
00:21:08:10 - 00:21:08:18
that's the
00:21:08:18 - 00:21:10:09
accounting systems.
00:21:10:09 - 00:21:10:23
And thinking about
00:21:10:23 - 00:21:12:04
how do we apply
00:21:12:04 - 00:21:13:01
those on farms
00:21:13:01 - 00:21:13:12
and how do we
00:21:13:12 - 00:21:14:07
track, verify
00:21:14:07 - 00:21:14:21
and measure them
00:21:14:21 - 00:21:17:02
through the
00:21:17:02 - 00:21:18:06
the supply chain.
00:21:18:06 - 00:21:19:03
So like
00:21:19:03 - 00:21:20:01
what you're going to go
00:21:20:01 - 00:21:21:14
buy at the grocery store
00:21:21:14 - 00:21:23:07
that has this
00:21:23:07 - 00:21:24:01
this reduction
00:21:24:01 - 00:21:25:09
at the end of the day.
00:21:25:09 - 00:21:26:11
Because I think there's
00:21:26:11 - 00:21:27:20
tremendous opportunity
00:21:27:20 - 00:21:29:19
there at this point.
00:21:29:21 - 00:21:30:08
There's still a
00:21:30:08 - 00:21:31:04
little bit of
00:21:31:04 - 00:21:31:19
figuring out
00:21:31:19 - 00:21:32:21
that people are doing,
00:21:32:21 - 00:21:34:05
but I think it's,
00:21:34:05 - 00:21:34:18
a very
00:21:34:18 - 00:21:35:12
exciting opportunity
00:21:35:12 - 00:21:36:00
to have, like,
00:21:36:00 - 00:21:37:03
a real world impact
00:21:37:03 - 00:21:38:12
from what this,
00:21:38:12 - 00:21:40:06
this area of research
00:21:40:06 - 00:21:40:23
has turned to be.
00:21:40:23 - 00:21:42:07
So,
00:21:42:07 - 00:21:43:06
what that looks like
00:21:43:06 - 00:21:43:23
and where that's at,
00:21:43:23 - 00:21:45:11
that's still
00:21:45:11 - 00:21:46:16
to be determined.
00:21:46:16 - 00:21:47:23
But, you know,
00:21:47:23 - 00:21:48:15
looking forward
00:21:48:15 - 00:21:49:03
to have lots
00:21:49:03 - 00:21:50:04
of exciting years ahead
00:21:50:04 - 00:21:51:07
in terms of where,
00:21:51:07 - 00:21:51:23
where this will go
00:21:51:23 - 00:21:54:05
from here. So,
00:21:54:05 - 00:21:55:00
I'm looking forward
00:21:55:00 - 00:21:55:15
to certainly not
00:21:55:15 - 00:21:56:17
waking up at 4 a.m.
00:21:56:17 - 00:21:57:05
all the time
00:21:57:05 - 00:21:59:06
anymore, but,
00:21:59:06 - 00:22:01:09
that is the next step
00:22:01:09 - 00:22:02:05
for me as,
00:22:02:05 - 00:22:03:18
as I look to wrap up here
00:22:03:18 - 00:22:04:09
in the next
00:22:04:09 - 00:22:05:08
couple of weeks.
00:22:05:08 - 00:22:05:22
Well, excellent.
00:22:05:22 - 00:22:06:15
Your future is bright.
00:22:06:15 - 00:22:06:21
Conor.
