Going past the economic value, what can component volume and percentage tell us about the farm level management and cow health?

Dr. Heather Dann

I think one of the important things that we need to look at is the pounds or kilos of fat and protein that our farm is producing. [S]ome of the common metrics that we're currently using here […] is the kilos or pounds of fat and protein shipped. Several years ago, we had these targets of about 2.7 kilos, or about six plus pounds. People were trying to join […] the six-pound club. And because of improvements in nutrition management as well as genetics, many farms have now been easily able to achieve that. And what we're seeing now is that those targets or those benchmarks are shifting. And we have many farms striving for that 3.2 kilos or 7 pounds plus of milk. And we're fortunate here at the Institute that we're at that level and a little above. […]

Chris Gwyn (04:10)

What else can this high level of component yield tell us about what's going on from a management perspective or cow health perspective?

Dr. Heather Dann

I think it really gives us a lot of insight into the general feeding practices and quality of the diet that's being had on farm. And one of the tools or metrics that we've been using for the last several years and have found quite useful is the fatty acid analysis piece that's come into play. […]

Chris Gwyn (07:13)

What do you see from your own experience or research as the most influential nutritional factors affecting component yield on the dairies?

Dr. Heather Dann

I think one of the most important things that we need to do is make sure we get the diet and that dining experience right to maximize milk components. And to me, that means that we need to focus on diet formulation, but also the management environment in which that diet is delivered to the cows. […]

But I think it just drives home the point that we can't just think about the diet formulation. It's beyond that; it's not just how it's formulated but how we mix it, how we deliver it, and then make sure it's available to the cows throughout the day. […]

Chris Gwyn (11:52)

Cow comfort management affects milk component yield in your experience and the research that you've done?

Dr. Heather Dann

I would say some of the work that we've done here at the Institute, as well as the Guelph Group, which is doing great work, and several other places, really drives home the point to me that we need to focus on optimizing key behaviors of those animals to maximize milk components. And that comes down to […] cow comfort. So, I'm thinking about the physical environment the cow is in, the social environment, not just with her own cow peers, but also as farmers, how we interact with our animals. And those things are going to influence the key behaviors that I think about when I'm trying to set cows up to produce as much fat and protein as they can. So, resting time, rumination time, and feeding time. And if we can get those things right in the cow's daily time budget, then she's going to be productive, healthy, and have a good well-being. So, some of the work that we've done here, we've gone out on farms and tried to understand why some farms have higher fat content than others. […]

Chris Gwyn (19:29)

Have you or others looked at what the time spread is in the delivery of feed? […]  Do we need to spread these meals by 4 hours, by 6 hours, or 12 hours?

Dr. Heather Dann

That's a good question. I think Trevor DeVries has done some work with meal delivery times, as well as Kevin Harvatine at Penn State, who has been doing some work thinking about timing of meal delivery. The Penn State work is really focused more on trying to understand the circadian rhythms of cows and the timing, and can we take advantage of a different feeding schedule that will allow cows to increase more milk components. And there is some work to that. I think one of the things that needs to be explored further is that if we're going to feed twice a day, should we be changing the diet composition? […]

Chris Gwyn (25:41)

Any other key take-home messages that you'd want a listener to focus on in our last 25 minutes of discussion here?

Dr. Heather Dann

I mentioned earlier that protocol drift is really important. People get bored with routine tasks, and on our farm, that's feeding, that's bedding animals, that's milking them. And we can't forget to make sure that we're going back and reviewing and emphasizing the importance of those activities. But really, I think for me the big take home today is that there's a simple recipe to getting more milk fat and protein and that really comes down to carefully formulated rations along with great forage quality and feeding management and then making sure we have good top notch cow management with a real emphasis on those transition cows. […]

Dr. Slesser, you recently published a study titled Wisconsin Farmers Share 

Their Stressors and Mental Health Care Needs Through Focus Groups. I was wondering if you could share the reasoning behind conducting the studies.
Dr. Heather Schlesser
I think we all know that Covid was hard on everybody, whether you were on a farm or not on a farm. And one thing that we saw here in Wisconsin is that with COVID, we had an increased spike in the number of suicides that were happening on farms. The CDC has even shown that between 2000 and 2020, there was an increase in the rate of suicides in rural areas by 46%. […] And our study team wanted to know why were these farmers not seeking help. Why weren't they reaching out to medical providers and getting assistance for the stress that they were feeling?

Chris Gwyn (02:55)
So you took a focused group approach to the study and it’s be interesting to know what were the key findings in the study.
Dr. Heather Schlesser
Interestingly, one of the main things they said is that they didn't feel comfortable going to the providers because they didn't have a farming background. They didn't understand that farming isn't just a job for these people, it is a way of life. You know, farmers identify as farmers. That is their whole entire life. It's not just “I'm going to go to an 8 to 5 and come home and be something else”; they are farmers. […]

The other thing that they said was a major stressor for them is, “We're already so busy on the farm doing that work that has to get done on a daily basis. We don't have this time to take off, to clean up, to drive into town, and to go see somebody that doesn't even understand what we're going through.” […]
Another thing that came out that we saw is that there's still that stigma. “We can't go see a provider because then everybody else in town is going to see our truck in the parking lot, and they're going to know that we need help.” […]

Chris Gwyn (04:58)
So what have you seen work in order to lower some of these barriers and these stressors?
Dr. Heather Schlesser

I would say the biggest thing that has really helped has been due to Covid. We couldn't meet in person with COVID, so they started Telehealth.
Telehealth has been a huge helper because there's no more getting changed. There's no more taking a shower. You can't tell if I smell. I might, but you can't. There's no truck in a parking lot that somebody is going to drive past and see. I don't then have to make a 20-minute commute into town and then a 20-minute commute back. So, Telehealth has really helped farmers because it allows them to get past a little bit of that barrier of time. […]

Chris Gwyn (06:16)
Can you expand a bit on the Telehealth program?
Dr. Heather Schlesser
Before COVID, it wasn't approved by a lot of insurance companies. In order to have a Telehealth visit, you had to go into the doctor's office in order to get insurance to cover that. So now, because it was allowed during COVID to do Telehealth visits, they have continued that, and they've continued them not only for mental health… […]

Chris Gwyn (08:20)
What are some of the key must-dos when it comes to transitioning farm business to another generation of owners?

Dr. Heather Schlesser
I would say that the biggest must-dos are that you need to develop a plan, then communicate that plan, implement the plan, and then evaluate if that plan is working. I think far too often we get hung up on transferring the cows, transferring the buildings, transferring the assets of that farm, and we forget that younger generations may not be doing all of the day-to-day, and they don't have the knowledge that it takes. […]

It takes a lot of time. A lot of farms that I work with are like, “Okay, I'm getting out in two years.” And I'm like, “Did you start your plan five years ago?” […]

Chris Gwyn (10:34)
I'm wondering whether you've looked into whether there are observations that you can share about how stressors on families and employees and ownership impact overall cow health and productivity.

Chris Gwyn (01:50)
I was wondering if you could summarize for the audience what has been discovered to date about B vitamin nutrition in dairy cows, in particular B12 and folic acid.

Dr. Melissa Duplessis
I started my career in research 15 years ago. I was a master's student at that time in Christiane Girard’s lab at Agriculture and Agri Food Canada. And she was the first to challenge the well-established dogma that dairy cows do not need an exogenous supply of B vitamins because their ruminal bugs are producing the B vitamins. But now, as you know, dairy cows are producing more and more milk, especially during the early lactation. We can wonder if it is still true that they don't need supplementation in B vitamins. That's why my master’s project was conducted. […]

Chris Gwyn (10:19)
I wanted to talk about some of the more recent research that you shared because it helps one to think about what some of the other needs are and future research. And in particular you shared a study about the impact of pasture or housed fed heifers fed at TMR. I'm assuming in the housing and the difference in folate and B12 concentrations and wondering if you could share those findings and how that might impact at the farm level.

Dr. Melissa Duplessis 
I think you are referring to my recent collaboration with Mary Beth Hall, who recently retired from the USDA. This study was conducted in the US with heifers at 5 months of age. And half of the heifers were raised on pasture receiving grains, vitamins, and mineral supplements, and the other half were in the barn receiving TMR (total mixed ration). And this is a preliminary study. We obtained blood samples from those heifers, and we analyzed folic acid and vitamin B12. And we obtained that heifers raised on pasture had a higher plasma folate, and the opposite was observed for vitamin B12. So, heifers raised on pasture had lower vitamin B12 concentration. […]

We did not record dry matter intake, but we also observed that there is a link with dry matter intake, and the ruminal synthesis of B vitamins could also be an explanation. And so, as I mentioned, it's a preliminary study. So, when we conduct a study, sometimes we have 10 other questions raised by that study. So it's normal, [it's the nature of the work we do].

Chris Gwyn (14:04)
I know recently you did also some work where you looked at pre calving nutrition and the impact of colostrum quality and yield and wondering if you can maybe touch base on that one. What does B vitamin levels look like in colostrum?

Dr. Melissa Duplessis
We conducted two studies with colostrum that have already been published. The first one was during my PhD thesis at Cornell University. So we collected colostrum samples from a project evaluating the impact of different levels of energy during the pre-calving period. And we observed that the impact on colostrum was that cows fed controlled energy prepartum had higher B vitamin concentration in colostrum. And when looking at the rations, we observed that the controlled energy had the highest NDF or fiber concentration. […]

Interestingly, we also observed that calves born to mothers receiving folic acid and vitamin B12 were heavier one day after birth. One hypothesis is that epigenetics, which includes folic acid and vitamin B12, has a link to epigenetics. So, it could be an explanation. So, it's a recent study that has not yet been published. We conducted it in 51 dairy herds, and we collected pre-calving rations served to cows in these herds. And we also collected colostrum from over 300 dairy cows. With our fancy statistical models, we evaluated the link between the prepartum diet and the impact of colostrum quality. […]

Chris Gwyn (19:26)
But certainly as you point out in your study, the effect on fiber and energy level again continuing having on the quantity and quality of colostrum is something that when struggling with those things producers should be discussing with their nutritionist.

Dr. Melissa Duplessis 
Yes. And if you are interested with our ranges, for example, like if you want to know the dairy ration of our herds, you can contact me, I would be more than happy to help in that regard.

Chris Gwyn (22:44)
What are some of the key points in your most recent research that you'd like to share with the audience?

Dr. Melissa Duplessis
I would like to say that from other studies I conducted, stressful events for the animals, for the cows or for the calves can modify or make a change in the B vitamin status of the cow. For example, a stressful event can be the calving, but it can also be heat stress or it can be weaning for the calf, or something like that. So, future research needs to be conducted to answer whether there is a practical implication of the change. Would animals benefit from supplementation? It's all good questions to be answered, hopefully in the future.

Docteure Duplessis, vous et vos collègues étudiez depuis de nombreuses années le rôle des vitamines B, en particulier celui de la vitamine B12 et de l’acide folique sur l'impact métabolique, productif et reproductif des vaches laitières. Avant de présenter vos dernières recherches, pourriez-vous résumer les découvertes à ce jour ?

Dre Mélissa Duplessis
J'ai commencé ma carrière en recherche il y a quinze ans. J'étais une étudiante à la maîtrise à cette époque dans le laboratoire de Christiane Girard à Agriculture et Agroalimentaire Canada. C'est vraiment elle la première qui a mis au défi le vieux dogme que la vache n'avait pas besoin d'apports extérieurs en vitamine B, parce que les microorganismes de son rumen produisent la vitamine B. […]

Mon projet de maîtrise se concentrait sur quinze fermes laitières commerciales au Québec. On a donné des suppléments d'acide folique, qui est la vitamine B9 et la vitamine B12, chaque semaine. Puis moi, pendant quatorze mois, j'allais sur ces fermes-là à chaque deux semaines pour prendre des données. Et on s'est intéressé à la productivité de ces animaux-là autour du vêlage. […]

Chris Gwyn (08:39)
On va parler des études plus récentes. Vous avez partagé avec moi une étude plus récente où vous avez examiné l'impact de l'alimentation des génisses au pâturage ou dans une étable, ainsi que les différences en concentration d'acide folique et de vitamine B12. C'est intéressant. Pouvez-vous partager avec nous vos conclusions ?

Dre Mélissa Duplessis
Vous faites référence à mon étude en collaboration avec Mary Beth Hall, qui a récemment pris sa retraite de l'USDA. En fait, c'est une étude qui a été réalisée aux États-Unis sur des génisses qui avaient environ cinq mois. Donc il y avait la moitié qui était élevée au pâturage, avec un ajout de suppléments et de minéraux et vitamines, et l'autre partie des animaux était élevée dans l'étable et recevait une ration totale mélangée. C'est vraiment une étude préliminaire. Tout ce qu'on a fait, c'est qu’on a fait des prises de sang chez ces animaux-là, puis on a évalué la concentration plasmatique en acide folique, puis en vitamine B12. Donc ce qu'on a vu, c'est que pour les animaux au pâturage, l'acide folique était plus élevé que les animaux élevés à l'intérieur. Et en opposition, les animaux élevés au pâturage avaient une concentration en vitamine B12 plus basse que les animaux élevés à l'intérieur. […]

Chris Gwyn (13:09)
Je pense que les recherches précédentes auxquelles vous avez participé ont démontré la teneur élevée en vitamine B du colostrum. C'est correct ou non ?

Dre Mélissa Duplessis
En fait, il y a deux études qui ont été publiées, qu'on a faites dans notre laboratoire, et il y en a une qui est en cours, je dirais, et ce qu'on a vu dans la première étude, quand j'étais à Cornell, pendant mon doctorat, on a récolté du colostrum d'une étude qui comparait différentes rations, différents niveaux d'énergie de la ration après vêlage. […]

Puis un autre projet qu'on a fait aussi, c'est lorsque la mère recevait des suppléments d'acide folique, vitamine B12 et biotine en prévêlage. On a récolté le colostrum de ces vaches-là et on a pu constater, sans aucun doute, que oui, la supplémentation en ces vitamines-là augmente ou améliore la qualité du colostrum. […]

Chris Gwyn (19:42)
Selon les recherches disponibles, quels sont les rôles des méthyles ou des vitamines B dans le rendement ou la qualité du colostrum ?

Dre Mélissa Duplessis
C'est une bonne question. Je pourrais mentionner que dans l'étude dont je vous ai parlé sur le volume de colostrum, et sa qualité, on va s'intéresser aussi aux vitamines B dans ce projet-là, mais on attend les analyses. Donc, je ne peux pas tout à fait répondre encore à la question, mais ça s'en vient. Ce que je peux dire, c'est qu’on a regardé la vitamine B12 dans ce projet-là. Les résultats sont déjà analysés. Ce qu'on a vu, c'est un petit peu comme dans le même sens que je disais tout à l'heure pour la vitamine B12, c'est que lorsqu'on augmente la fibre de la ration, ça augmente aussi la concentration de B12 dans le colostrum, ce qui vient un petit peu en contradiction avec ce que j'ai dit tout à l'heure à propos du volume de colostrum, c'est carrément le contraire que je vous ai dit. Donc c'est ça qu'on est dans le biologique. Comment fait-on pour optimiser le colostrum sans nuire à une autre composante aussi ? […]

Chris Gwyn (21:48)
Est-ce qu'il y a d’autres points clés que vous voudriez partager avec les nutritionnistes, les producteurs qui écoutent RumiNation ?

Dre Mélissa Duplessis
Je crois que j'ai dit beaucoup d'informations. C'est certain que je n'ai pas discuté de tous mes projets. En résumé, ce que je peux dire, c'est que récemment, une des hypothèses que j'ai, c'est que tout événement stressant chez l'animal, surtout lorsque la vache produit beaucoup de lait, par exemple, ça peut être un stress de chaleur ou toute transition qui est un stress peut avoir un impact sur le statut en vitamine B de ces animaux-là. Mais à savoir si ça a un impact biologique, métabolique, ce sont des questions qu’il me reste éclaircir. J'ai beaucoup de questions en suspens, finalement. Mais ce que ça suggère, c'est que tout stress chez l'animal peut avoir un impact sur les vitamines B et que peut-être l'animal aurait avantage à recevoir un supplément ou un apport extérieur.

Dr. Devries, your lab has been extensively and intensively looking at cow management and nutrition factors and their associations and correlations with early lactation outcomes. Why don’t you give us an overview of this most recent study design.
Dr. Trevor DeVries
Yes, this is a large study that we recently undertook with a large cohort of dairy farms in southwestern Ontario. […] Not specifically looking at milking system effects, but looking at the management of those cows during the dry period, their nutritional management during that time period, and looking at not only how it impacted the cows during that time period, but also those cows as they transitioned after calving, and looked at the fresh cow success of the cows on those farms and correlating that back to differences in management, differences in environmental conditions, and particularly things like heat stress.

Chris Gwyn (05:22)
One of the factors that came out is that you and your team demonstrated pretty large variation and differences between formulated diet and the diet that was fed at the farm level. And I was wondering if you could dig down a little deeper into that and share some of the other key findings and information from this study.
Dr. Trevor DeVries
One of the factors that we were interested in from a stress standpoint was dietary and looking at differences in diets. And then, one of the key things that we were really interested in was how closely those diets matched what was formulated for those farms, as well as how much variation we saw within a farm over time in terms of the diets that were delivered to the cows. […]

Chris Gwyn (12:08)
In the study, your lab looked at heat stress impacts on the cow and its relation to markers of stress associated with changes in physiology and metabolism. I'm wondering if you could share a bit more details with the audience and what you can conclude from the findings in the study.
Dr. Trevor DeVries
We knew that one of the primary factors that we were hoping to key in on was that heat stress. And so that was in itself measured through doing cow-level observation, continuous observation over time. We had records of temperature and humidity, so we could calculate THI within the close-up pens and fresh cow pens on these farms. […]
We could look at how much heat load those cows were incurring. But then we wanted to be able to link that to the cows themselves and what they were experiencing. And one of the measures, which was quite interesting, was looking at the eye temperature of the cows as a new way of looking at how much heat load those cows have. […]

 

Chris Gwyn (22:13)
Speaking of energy balance, [it looks as if] heat stress had an impact on glucose production. Is that something that you can comment on, as well as findings that you found from your paper?
Dr. Trevor DeVries

We didn't look directly at glucose ourselves, but definitely from other work that's been done by other research groups, we know […] there's a huge potential draw, or not even potential draw, there is a huge draw of glucose when that cow calves and she starts lactating and blood glucose levels drop on a fresh cow versus a dry cow. Because again, the amount of glucose getting taken out of the system for making lactose and making milk, there's a huge demand there. And so that drive to produce milk, and then the need for lactose trickles down to a need for glucose. And one of the challenges is that when there are things like heat stress going on, we tend to see not only things that may reduce intake in cows, that may lead to less kind of substrate availability for producing energy and glucose, but also inflammation in the gut, and things like that can cause leaky gut […]

Chris Gwyn (24:26)
Is there anything else that you wanted to add in that field of stressors and this study that you wanted to elucidate or impact for the audience?
Dr. Trevor DeVries
We talked about some of the primary stressors that we were really interested in, at least in this research, around heat stress, some of the management-related things, grouping of cows, and movement of cows. One of the things that we haven't gone too deep into with this data set, but we know from other work, is the crowding of cows and competition of cows that can also lead to stress and more negative outcomes. And again, we know that anytime that we overcrowd cows, whether it be at the feed bunk, whether it be at the lying area, whether it's a stall or a pack, or even the water trough, we're going to see a negative impact on the behavior of the cows, which can then result in negative outcomes. […]

Chris Gwyn (28:21)
Before we wrap up, given what you and your team has been discovering in this research, recommendations that you would like to reinforce for dairy producers, nutritionists, veterinarians and other advisors.

Dr. Trevor DeVries
We talked about the variation in controlling variability and being consistent. Consistency is huge. And so again, one of the first things from a management standpoint, is to make sure we're consistent. And like we mentioned before, if things are consistent and still not working the way we want things to be working, then we start evaluating those, those protocols, and those systems that we have in place. […]

Chris Gwyn (

30:15

)

What's next in your research, Dr. DeVries?

Dr. Trevor DeVries

This is an area that we continue to work on, this area of management of transition cows. I'm very interested in the other transition that we talked about with cows, and that's from lactation to the dry period. And again, there is a lot of focus on the transition from the dry period to calving. But we also note that there are potential challenges associated with drying off cows that are heavy in lactation, not only from an immediate welfare standpoint, and again, some older research on the effects on those cows from a pain standpoint, even, with utter engorgement, utter health, is also very challenging. But then those two factors actually influence inflammation in those cows. […] And so that's kind of an exciting area that there are others working on and we're going to be looking at as well, hopefully in the near future.

Chris Gwyn (03:02)

What is important for producers and nutritionists to consider when optimizing stock and density in their dairies?

Dr. Rick Grant (03:10)

Well, that's the big question, isn't it?

And there are at least two or three main factors that we can get into today. One would be just, I had an aha moment a few years ago when a grad student and I realized that we need to think about overcrowding as a subclinical stressor. That allows us to think about how the same level of stocking density of stalls or feed bunk doesn't affect every herd the same way because the point at which a subclinical stressor affects a cow within a herd really is a function of the quality of the management on that dairy as well as the quality of the facilities. […]

The other thing, I would say is, we know this, but we don't think about it enough. When we say stocking density, we count stalls, we count cows, or we count headlocks, we count cows. But we need to always step back and think within a pen, what is the experienced stocking density from an individual cow's perspective? […] I think that's something we need to think more about in terms of managing a given stocking density on a specific farm, the cow's perspective. […]

We did a study where we found that cows tend to prefer the stalls nearest the pen exit, particularly lame cows. And doesn't that make sense? If you're a lame cow and walking is a bit challenging for you, you may have 50 stalls to choose from, but you choose the ones that are closest to the exit or the entrance. That tells me right there that a simple mathematical calculation of stocking density would fail those moderately lame cows because they don't have 50 stalls available to them. They might only have 10 or 12 if you allow them to express their natural desired resting behavior. That's something we need to wrestle with in the industry.

Chris Gwyn (07:13)

What are some of the key metrics or cow observations that we should follow in order to ensure that what we use on the farm, as far as stocking density, helps us to maximize that component yield or profitability?

Dr. Rick Grant (07:30)

Well, certainly, the things that we normally measure, like milk yield, intake, repro health, all of those things can give us clues in terms of how well the cows in that pen are dealing with the day-over-day chronic subclinical stress of the overcrowding. […] But at some point, every herd will have a problem with additional stressors. And how many stressors are there on a typical farm? The list is long. You might say time outside the pen is too long. Are all the stalls comfortable? Is feed available 24/7? All these things are critical factors that can snowball or add to the negative consequences of some subclinical degree of overcrowding. […]

Chris Gwyn (10:05)

What are the essential factors in managing these cow pens if we're managing to a higher level of stocking density?

Dr. Rick Grant (10:12)

We did some work a number of years ago. We looked at almost 80 farms in New York and Vermont, and it was all breeds. Jersey and Holstein breeds, tie stalls, free stalls, and some robotic herds. The things that rose to the top in terms of essential factors […] is that they don't go as high in bunk stocking density. They just don't push the system as hard. That's simple to say, but that was the biggest factor. In fact, we looked at all the variations in terms of milk fat and protein across these 69 herds; 65 % of the variation in component output was due just to bunk stocking density, not necessarily nutrition. […]

Chris Gwyn (12:58)

What are the key takeaways that you would share with the audience: nutritionists, veterinarians, and primary producers? If they're going to manage through stocking density, what do they need to really pay attention to?

Dr. Rick Grant (13:12)

I think the best answer for that hit me a few years ago. I was reading this paper on robotic milking systems and automated milking systems. It was over 120 farms. […] What struck me is the factors on the farm that contributed to the best milk yield, and the best lameness outcomes were the exact same list of factors that we've seen with free stall barns and probably even tie stall barns to a certain extent. But it's feed push ups and deep-bedded sand in these 120 farms. Those two factors, feed availability, comfortable stalls, and deep-bedded sand, resulted in 4 to 5 pounds, at least more milk production on average. The other thing about lameness […] is the same as the free stall herds: greater bunk space, feeding frequency, and deep-bedded stalls. You sound like a broken record, but those factors rise to the top in every study that I'm aware of. […]

At the end of the day, if you can get that done, you're going to have a good balance in your herd between eating time, and eating behavior, and you're going to have that recumbent rumination, that lying down rumination that we think is so critical to cow health and performance.

JEFO recently celebrated its 40th anniversary. Can you share with us and with the audience the story of how JEFO started?

Jean Fontaine
JEFO started very modestly. I was out of school, 25 years old, and I had a choice to declare bankruptcy or try something. And I had a vision to offer our industry different source of material, to be more competitive. And it started like that. The snowball effect started gradually with one or two products, then the other ones were added altogether. So, simple start, amazing development.

Chris Gwyn (02:49)
This started and centered our culture of “Life, made easier”. Can you share with us what inspired this mission and give a few examples of how you and your employees embody this statement?

Jean Fontaine
After meeting with some experts who guided us about establishing our motto “Life, made easier”, we realized that we make life easier for the buyer, and their supply chain, with our quite fair size inventory warehouses. Life made easier by sourcing with our expertise, we know what is a product that fits. And, with the efficacy. Then, life made easier for the truckers. We have a nice system of logistics, able to make quality pallets the way we ship our products. So, it's life made easier for everybody in the chain of activity. […]

We've seen over the last few years the idea of artificial intelligence gaining interest across the world as the livestock industry keeps evolving rapidly. In your thoughts, what are the main producer challenges and market changes that you foresee and what will be the key attributes of those who successfully adapt to these changes?

Jean Fontaine
Farmers need to get access to their numbers and to have them handy to be able to know what's going on rapidly and correct the situation. Before AI, it was not easy to take a note and then put all these things together. Today, there are more and more tools to do that. Some companies offer on-site, cameras, and sensors that can feel the water flow, the temperature, the ammonia level, and the behavior of animals. So, all this will bring precision and the farmers will know what's going on. And sometimes we don't realize they have a hell of a challenge in their life. Many factors must be controlled. So, to do that, AI will bring us tremendous capacity. And then you have to adapt to change. The future with AI will change the planet. […]

So, there's no reason that people can object to this change of knowledge. IPhones have been around for 15 years. Can you imagine your life without an iPhone today? Try to figure out your life today with no portable phone and then no smartphone. We can talk to the vets before they get there. They can have an edge about what is going on.

It was believed that the rumen of the cow would do everything for the cow. Initially, we discussed having some AD plus B vitamins be protected to escape the rumen. Maybe you leave like 10 or 15 percent in the rumen to nourish the bugs and to go bypass. […]

Today, we have discovered that very small quantities bypassing the rumen make a tremendous impact. From the expertise in ruminants, we went back to poultry and swine, and we discovered an amazing approach. And the concept for us is to prevent feeding the pathogens in the intestine of the cow, of the pig, of the poultry. And we have developed data on that aspect that is intriguing to a lot of people. Now we have the capacity to go after the rumen and after the stomach in monogastric. […]

Chris Gwyn (10:44)
Can you explain how we do that within the Jefo Matrix Technology?
Jean Fontaine
Our technology uses vegetables, 100% vegetable carrier, fats, which have high melting points. We have some specific formulations of carrier with fatty acids and triglycerides, that will allow it to be released in the small intestine. We know how to slow the lipase to have a delivery further down in the intestine. This is why we're gaining so much momentum with the customers.

Chris Gwyn (15:08)
Often in meeting with clients, they express to me the admiration they have for the entrepreneurship and the visionary aspect that they see in you. In this area of a visionary in the field, what do you feel is your contribution to the world of dairy cows?

Jean Fontaine
The contribution is to bring precision to the intestine of the cow for nutrition. People have injected vitamins. People have done a lot of drenching the cows. It was all behaviors to compensate for the problem they have at calving. Our technology, to protect against rumen degradation, has allowed us to give them a solution which is much less demanding on staff. The first reason people will leave the farm, the young guys, is the problem of calving their cows. They never quit because they drive the tractor. They never quit because they pass the broom. They hate to grab the cow and drench her and all the other precautions because of calving issues. When the placenta doesn’t get out, they hate the smell of the barn and the cows suffer. If the placenta gets out with the calf a couple of hours later, as they do with our solution, we make their life easier. It's another phrase that fits. It's life made easier for calving problems. Our contribution is to give maybe more fun to the farmers solving their main problem of calving.

Chris Gwyn (17:02)
Could you share the key factors or strategies that contribute to the seamless integration of the family dynamics into a business and how you've worked to foster collaboration and harmony among family members while building this thriving business which is Jefo?

Jean Fontaine
I was so surprised to learn that 85% of companies die with their president. I was not conscious of that. Today, I'm lucky, out of seven kids, I have three who are old enough to be involved with us. Émilie, Jean Francois, and Anthony. I think I transmitted to them the passion for what I do. I retired 42 years ago. Now I play the role of the president of the company. I play the judge’s role; I play the father’s role. I am still an actor, but I play roles. Today, the kids realize it's valuable. People respect and appreciate if you give your time for a purpose. To define the purpose of life, it's a challenge. The first time I was asked the purpose of my life; I jammed the question. So, we have to find out our purpose in life and share that fun of helping others. If you are useful, you have a future. I teach my kids to be useful, to be passionate, to love people, to accept also to be their friends. So, I teach them: The more you give, the more you get; the more you give time, attention, help, and love, and you can talk about money as well. Whatever we can do for others won't come back to us at a high speed. So today, for me, it's a very big emotion to know that when I leave, people will do that. Success, if it's only one life, is not success. Success is measured in time. So, I have many chances to be successful.

Chris Gwyn (19:09)
Could you share insights into how you strategically built and nurtured your professional network or circle of people who influenced you, advised you, and networked with you and what key principles or practices you believe contributed to the growth and sustainability of Jefo?

Jean Fontaine
It may sound easy to say, but we have the privilege to be in an industry where we have to be friends for a long time. If you sell me a house, I'll buy my next one maybe 20 years from now. It won't happen every month. In animal feed, we have to fill the pipe. So we need to talk to each other on a regular basis, weekly, monthly, quarterly. So we have a business of developing proximity and friendship. If you have proximity to people, you learn about their problems, their issues, and their challenges. Can we help them? Sometimes, yes, we can. This is making a rich relationship with the customer. And if the customer is happy, you have a good business. It's a fruitful business and it can be contagious. They're going to talk to others. I teach my staff to be lazy and I'll define laziness: Do it right and make people talk about you. Your reputation will be your best future. You have to be useful to somebody. If you're not useful, you're going to be out with the game.

Chris Gwyn (20:48)
As we conclude, maybe a message that you can pass on to the next generation of entrepreneurs in the livestock and poultry feed industry. What would you share with them?

Jean Fontaine
Don't believe the past will be the future. Whatever happened in the past without AI, without all these technologies, would not necessarily be proof for the future. We have to change. The world we are addressing is something invisible. So, we have to be open, and love change instead of avoiding it. Please be all excited by the change for the best. We are living in the best time for the human race. […]

We have to be hungry for change and not fear to adapt and progress together. And this is needed for everybody together. Not one guy, one company, one team. Everybody should be in the same kind of thinking pattern.

Tout récemment, Jefo a fêté son 40ᵉ anniversaire. Pouvez-vous nous raconter les débuts de Jefo ?

Jean Fontaine
Ça prend un petit peu de temps à expliquer tout ça, mais les débuts étaient très modestes. J'ai commencé à 25 ans avec le choix de faire faillite ou de commencer à faire de l'argent. Dans le domaine des luminaires, c'était le bicarbonate de soude qui était granulaire contre les Américains qui avaient le monopole du marché. Donc on a commencé modestement dans une maison avec un appartement qu'on a modifié avec des bureaux. Aujourd'hui, on a le campus Jefo à Saint-Hyacinthe et c'est un centre d'information. Jefo a commencé au Québec, ensuite en Ontario, après le reste du Canada et le marché mondial. Le petit pas, c'était la bonne technologie pour grandir sans s'enfarger. […]

Vicky Brisson (03:06)
La culture de Jefo est centrée sur «Life made easier» ou «La vie ne plus facile». Qu'est-ce qui a inspiré cette mission et est-ce que vous pouvez nous donner quelques exemples de la manière dont vous et vos employés incarnez cette déclaration ?

Jean Fontaine
La vie est plus facile, ça résumait l'approvisionnement plus facile avec différents fournisseurs. L'entreposage pour les produits, on dit en anglais «Just in time», l'approvisionnement spontané; il y a tout chez nous. Et, avec la recherche, on rend la vie plus facile aux chercheurs parce qu'on a rassemblé plusieurs marchés différents avec le même objectif de faire plus avec moins. Donc, ça a été ça qui fait le slogan «La vie en plus facile» la première fois et depuis tout le monde accepte que c'est vraiment ce qu'on fait.

Vicky Brisson (4:31)
Avec l’arrivée de l’intelligence artificielle, quels sont les principaux défis que les producteurs devront relever ? À votre avis, quelles seront les principales caractéristiques de ceux qui vont réussir à s'adapter ?

Jean Fontaine
S'adapter. S'adapter au changement. Vous savez que la plus grande crainte des gens c’est de changer. Donc, l'agriculteur et l’agricultrice vont apprendre à mieux mesurer ce qu'ils font. Avoir accès à leurs données, que ce soit la température, la qualité des fourrages, tout ça grâce au système d’intelligence artificielle. Ils vont être capables d'avoir une plus grande précision. Et quand on peut mesurer ce qu'on fait, on peut l'améliorer. Sans mesure, c'est très difficile de s'améliorer. Donc, c'est une voie que personne ne peut éviter. […]

Vicky Brisson (05:36)
Depuis plus de 20 ans, vous apportez des innovations à l'industrie de l'alimentation animale avec la technologie Jefo Matrix. Est-ce que vous pouvez nous expliquer pourquoi c'est important de micro-encapsuler les nutriments ?

Jean Fontaine
C'est un concept. Si on se rapporte au tout début, quand j'ai commencé en 88 à vendre des acides organiques enrobés pour compétitionner les facteurs de croissance chez le porc, on s'est moqué de moi. Aujourd'hui, le monde des médicaments a beaucoup baissé. Les additifs alimentaires qu'on donne chaque jour pour moduler la flore intestinale […] sont de moins en moins à la mode, puis même à certains endroits, ils sont bannis. Avec la technologie de matrice que nous avons, on prévient le bris de nos molécules, de nos nutriments avant d'arriver à l'intestin où ils sont absorbés […].
Sauf que nous avons découvert qu'en enrobant avec des matières grasses 100 % végétales, on vient qu'on traverse le rumen à 85 % et on relâche lentement avec la lipase qui brise le gras les nutriments qui sont bénéfiques pour la vache laitière ou le bœuf. Dans la volaille, la même chose s'applique. On va résister au PH acide, au phytate, au calcium, au soufre qui vont venir lier les différents nutriments et les rendre indigestes à l'intestin. […]

Vicky Brisson (09:27)
Vous observez depuis plus de 20 ans l'impact de la nutrition de précision sur les animaux. Est-ce que vous pouvez résumer pour nos auditeurs quelles sont les principales observations que vous avez pour ces animaux ?

Jean Fontaine
Première chose qu'on peut voir, c'est l'efficacité digestive. […] La principale raison pour laquelle nos jeunes hommes et jeunes femmes quittent les fermes, ce sont les problèmes liés au vêlage. Donc, quand une vache va vêler, les gens préviennent avec différents traitements qu'ils ont appris à faire parce qu'il n'y avait pas la technologie que nous avons aujourd'hui. […]

Avec notre approche de précision intestinale, on livre ça tout ensemble ces fameux coenzymes, ces cofacteurs d'enzymes et les oligo-éléments. […]

Vicky Brisson (11:15)
En tant que visionnaire dans ce domaine, quelle est, selon vous, votre contribution au monde des vaches laitières ?

Jean Fontaine 
Si on réussit à améliorer le vêlage et à avoir une vache qui va pouvoir faire plusieurs lactations consécutives parce qu'elle a une meilleure santé générale causée par cette nutrition de précision. Je pense que nos éleveurs gagnent beaucoup. […]

Vicky Brisson (12:23)
Vous avez créé avec succès une entreprise familiale. Pourriez-vous nous expliquer comment vous avez favorisé la collaboration et l'harmonie entre les membres de la famille tout en bâtissant une entreprise prospère ?

Jean Fontaine
Ça c'est une bonne question. Parce que pourquoi les enfants s'intéressent à ce que j'ai construit ? C'est qu'ils ont compris que j'avais du plaisir à faire ce que je fais. On peut guider les gens par l'exemple. Les enfants ont vu que j'avais du plaisir à recevoir des gens, à visiter des gens, se créer un réseau d'amitié à travers le monde. Parce qu'on a l'avantage dans notre industrie de vendre ou de fournir des produits et des conseils toutes les semaines, tous les mois. Nous, dans notre industrie, on établit la proximité. Chez Jefo, on aime recevoir les gens. Ici, au campus et même chez moi, on a développé cette amitié de proximité avec les clients, les fournisseurs. C'est important. Si tu n’as rien à vendre, tu n'as pas de produit à vendre, ce n’est pas bon. D'avoir des fournisseurs, mais pas de clients, c'est pareil. Donc, tout est relié ensemble. Mais je crois que mes trois enfants, Émilie, Jean-François et Anthony ont su apprécier ceci de mes 40 ans de vie d'affaires. Et aujourd'hui, ils vont prendre le relais. […]

Vicky Brisson (18:07)
Pour conclure, pouvez-vous nous faire part du message que vous souhaitez transmettre à la prochaine génération d'entrepreneurs de l'industrie ?

Jean Fontaine
La plus belle chose que je peux leur suggérer, c'est de ne pas avoir peur du changement. […]

Le changement qui s'en vient va être impressionnant. Certaines personnes ont peur du mot : intelligence artificielle. Elle est là pour nous aider. Il faut accepter le changement et oser. […]

Moi je vous dis que la vie est pleine de belles choses. Il faut s'amuser à la désirer.

I'd like to know a little more about why you became interested in researching ideal topic density.

Dr. Albert De Vries
I actually had an intern student from the Netherlands, and that student was very interested in welfare. And I said: If we just do welfare in the US, maybe that's not of primary interest to producers, although I understand our producers are all interested in welfare aspects as well. But I'd like to put dollars into whatever we do with cows. And so we did a little digging and came up on the topic of stocking density, the economics of stocking density. It's really a fascinating topic because there are some welfare implications but there are clearly also economic implications. […]

Chris Gwyn (03:23)
What are the key influencers of the economic return when you're evaluating where a farm is evaluating its optimal stocking density?

Dr. Albert De Vries 
I think we should start by defining, what we mean by stocking density. Different metrics of that. We're not talking about dry lots here. We're talking about free stalls. We were also not interested in fresh cows or dry cows, which I think all experts agree should not be overstocked. We're looking at lactating cows. And we also did not think that feed bunk space was a limiting factor. So, in our research, we really looked at the number of cows over the number of stalls in a pen. And if that is 100%, then you have one stall per cow. And if it's like 120%, you have 120 cows for 100 stalls. So that is where we sort of limited our research to. And secondly, I think it's important to get the economic principle right. What are we trying to optimize here when we're talking about economics? […]

Chris Gwyn (11:20)
In that study, you looked at milk production. Did you look at component yield?

Dr. Albert De Vries
I think we looked at component yield, but I don't remember seeing anything necessarily, because, of course, we get paid for components. I don't think it was very clear that either fat or protein, for example, was reduced by overstocking.

Chris Gwyn (14:10)
If there are some other issues that you wanted […] to highlight, we can do that.

Dr. Albert De Vries
I haven't really said much about welfare yet. I mean, the student I work with was really interested in that, and I think it needs to be on our minds, too. So, if we say we just want to take care of the cow, we probably don't want to overstock. Cows are probably compromising welfare, perhaps a tiny bit only if we start to overstock, and more when we overstock more. So, we don't know how to square that with profitability. But obviously, that needs to be in our mind as well. […]

Chris Gwyn (16:34)
Can I ask you a further question about that? Because I'm not an economist, but where does cash flow come in if a farm needs to increase cash flow? Does that kind of counter go against optimal stocking density in low milk pricing?

Dr. Albert De Vries
I think you're on the right track there because we assume our fixed costs are independent of the number of cows. So, we would add cows to it up to the point of maximum optimal stocking density, which implies that, for that pen, the highest cash flow. And so, with low milk prices, we reduce cow numbers, because if we don't, our cash flow is going to be even less. So, cash flows, in this analysis, and this is obviously what I call a steady state; we sort of permanently are at a high or a low level of stocking density, but it's the same thing. So, the question becomes practically different: Well, my milk prices change, and I may or may not have the cows. What is the long-term response to stocking density? Those are harder to answer because, again, we don't know the long-term response to stocking density per se, but essentially, when we optimize our stocking density, we're optimizing the cash flow, the amount of cash made there for that pen on that day over time.

Chris Gwyn (20:40)
As we wind up, I always like to ask, what are some of the key take-home points for producers and nutritionists and lenders, in fact, and veterinarians, when considering evaluating the impact of a stocking density on the farms they work with, what would you recommend they look at?

Dr. Albert De Vries
If I put on my economics glasses, if you will, then I think overstocking a pace. And like last year in the US, we had actually good milk prices. […] At the same time, we learned through the research that it sort of is farm-dependent in terms of prices and what are the losses that you observe. And so we have a spreadsheet available for listeners that they can work with, and play with. Probably the easiest way to get there. If you go to Google and you look for “dairy stocking density calculator Florida”, I think we end up number one on the Google search list there. And there's an EDI extension publication there. And that publication lays out what the research was about, hopefully in not too scientific terms. And there's a link to a calculator we used as well that we made available for folks to play with. […]

As an introduction, can you explain what de novo fatty acid synthesis is?

Dr. Débora Santschi
To me, the fatty acids are basically if we would take that black box of fat, the milk fat test, open it up, and look at what's inside of it. So, if we take, for example, a herd that is at 4% fat, if we open it up, we can see what makes up that 4% fat and see where those fatty acids come from. […]

The de novo fatty acids are one of those groups of fatty acids we find in the total fat. It represents, depending on the herds and the cows, roughly between 25-30% of the total fat. And those are the fatty acids that are synthesized in the mammary gland of the cow. […]

Vicki Brisson (04:00)
What impact does that milk fat composition have on the cow? And what are the periods when the fatty acid profile is more likely to vary?

Dr. Débora Santschi
I think it's very interesting to look at it from a cow’s side and also from a herd’s side. So, if we take the cow example, a cow in very early lactation, we all know that she's using her body reserves to compensate for that very high demand for milk production. In that case, a big chunk of her fat content will be preformed fatty acids. So, in very early lactation, we see roughly 50, or sometimes even slightly more, as a percentage of her fat being the preformed fatty acids. And in that case, the de novo will be very low and increase slowly over the first 45, 50, and 60 days of lactation. […]

If we look at it on a herd level, when we do some ration change, when the forage digestibility changes, but we don't notice too much. All those little effects can also have an impact on the de novo content of the bulk tank sample. In that case, because bulk tank samples are often analyzed very frequently, then we can get a rapid insight into something that we might not have noticed on the farm level. […]

Vicki Brisson (05:46)
Knowing that the fatty acid profile of milk matters, what can we do to promote the production of de novo fatty acids?

Dr. Débora Santschi
The de novo fatty acids are the result of being produced in the mammary gland from rumen volatile fatty acids. So, everything that we can do to maximize rumen volatile fatty acids will have a positive impact. So, we often focus on the ration. So, of course, having a highly digestible ration, well balanced with all the nutrients that are required, is really important, but we need to keep in mind everything around it. […]

Vicki Brisson (07:33)
Can you expand on specific nutritional solutions that our listeners may want to consider? 

Dr. Débora Santschi
The way we train our people, and I just want to mention, we have a lot of information that is available directly on the website as well to help understand and find solutions, because it's going to be very herd specific. But when I look at a herd, I look at the fat test, and the protein test, because those are values we know and we handle very well. I look at the MUN value because to me, it's important to look at the overall protein balance as well, and then I go and look at the fatty acid profiles. I always start with the de novo, then look at the mix, then look at the preform. That's my way of addressing a report. […]

Vicki Brisson (10:01)
Beyond just the amount of de novo fatty acids produced is also the variation in fatty acid levels. So, what are the impacts of that variation in fatty acids and how can we address it?

Dr. Débora Santschi
Very good question. I think, again, there's some information on the cow level, there's some information on the bulk tank level. I like to work on the bulk tank level first because it's every second day in our case, so it helps to get a very accurate and up-to-date overview. However, the downside is that it's only on a farm level, it's an average, and I have no idea of the distribution of it. […]

When there's a lot of variation on the bulk tank, we see it a lot in the inconsistent feeding herds, in the herds that have a lot of changes in the ration, where the forage composition is not very constant. […]

Vicki Brisson (13:44)
Can you help us understand or explain the link between B vitamins and fatty acids?

Dr. Débora Santschi
To my knowledge, there hasn't been too much specific research combining the two, I think that's a very interesting area to explore. I think if we take one step back and look at the whole picture, rumen health, optimizing the bacterial populations we have in there, and making sure that this is all functioning well should also be reflected in the de novo synthesis. […]

Vicki Brisson (16:23)
Can you just expand a little on the tools that you have at Lactanet and that you offer your producers on how to monitor de novo fatty acids and how they can use that as a decision-making tool or to help them identify possible issues on the farm?

Dr. Débora Santschi
At Lactanet right now, back in 2020, we launched what we call PROFIlab. That's our milk fatty acid monitoring tool, currently available in Quebec, and in some Atlantic provinces, at the bulk tank level for now. […]

We do have a prototype for the cow level. We tested it with some of our advisors, and some of our farmers. So, 2024 should see that prototype become a real tool, this time not only in Québec, but across the country. […]

Vicki Brisson (19:13)
Can you share your take-home messages? Maybe three or so for nutritionists, vets, and producers when they think de novo fatty acid synthesis in milk?

Dr. Débora Santschi
I'll say the first one is that black box. I like to see it like that. We're opening up the fat and understanding better what makes up that fat. So, get a deeper insight into your fat test, which is what we're being paid for. 

Second one, dare to use it. Just try. Just try something. Ask questions. Get the information you need to start working with it and try to have that value change. Try to cause an impact on that de novo value to make it move. And you'll see how it can be powerful for your herds. 

And the third one is, please, any suggestions, any ideas, any questions? You're more than welcome to contact us because as I just said, I think that's how we learn altogether and that's how we can make it even better and then share that information back. […]
