The Nutritionist

Our own, Tom Tylutki, will use the CNCPS-based AMTS formulation model to look at the effect various feeds and diets will have on emissions. The excretion and emission equations in the CNCPS allow you to formulate with those results in mind. Tom discusses some of the thoughts and products mentioned in earlier webinars but then pivots some what to look at where real efforts can be placed. What are the best strategies. For more of Tom’s past formulation focused webinars; look at 2015, 2016, 2020, Feb 2021, and Oct 2021

Dietary solutions to inhibit ruminal methanogenesis: Where are we now, where do we go next, and how do we get there?

Dr Joseph McFadden leads a research program at Cornell University focused on dairy cattle nutrition with a focus on improving nutrient digestibility, liver and gut function, and the efficiency of milk production. He is leading the development of a Cornell program and center to evaluate the effects of feed additives and drugs on methane and milk production using standardized procedures with the development of a climate-controlled respiration chamber system to study enteric methane emissions from dairy cattle.

Jude and Sara are both experts and vocal advocates on sustainable farming practices. They gave us an overview and some pointers for communicating to the non-farming community. There is a lot of misinformation offered on social media and in the press. We learned some facts and some methods of best sharing our knowledge

The Real Story about Climate Change and Animal Agriculture

Dr Frank Mitloehner, professor and air quality specialist in cooperative extension in the Department of Animal Science at UC Davis. The CLEAR Center brings clarity to the intersection of animal agriculture and the environment, helping our global community understand the environmental and human health impacts of livestock, so we can make informed decisions about the foods we eat and while reducing environmental impacts. This talk is the second time we have featured Frank on the Nutritionist, you can listen to his 2020 webinar here.

Dr Elliot Block, Research Fellow and Director of Technology in Animal Nutrition and Food Production, gave a talk on the sustainability and uses of palm oil in dairy diets. He laid out the facts and debunked the myths of feeding palm fats.

Dr Van Amburgh’s talk focused on the science and progress that has been made in lessening the environmental footprint of milk production. His presentation provided some details that help us better understand actual impacts and changes that can be made to decrease excretions and emissions going forward.

When Russia invaded Ukraine in February 2022 it exacerbated an already volatile world pricing structure for feed, fuel, labor, and nearly every other input in food production. There is serious concern of global food shortages, extraordinary food cost inflation in countries that can get food, and supply chain problems for those countries that do have food to export. Combined with predictions of continued drought in major grain producing areas and the complications of entering the third year of a global pandemic, the outlook is grim. Tom looks a some of the issues he is seeing and advises on strategies for maximizing production not only to weather the crisis but also to make as much milk for a struggling world food supply. This is a long, scary webinar. We had great questions from around the world. We were honored to be joined by most of our AMTS distributors who asked questions or offered insights on their part of the world.

Dr. Sam Fessenden gives us a very personal tour of his Silver Spirit Dairy, the Minnesota Dairy he runs with his wife and her parents. He shares some of the building, cow behavior considerations, and nutritional approaches he has taken in his first year working in a 120-cow with two Lely A5 milkers. This is Sam’s third Nutritionist Webinar and you can find his webinars on using Farm Data in Nutritional Models and optimizing formulating in the CNCPS model in our archives. Not just a great speaker, Sam also helped create the Robot Tutorial in our AMTS Video manual on YouTube. This webinar concludes our 2021 Nutritionist Series.

The November episode of The Nutritionist 2021 hosts Daniel Scothorn of Scothorn Nutrition. He takes us on a tour of one of his clients in Nova Scotia, Canada looking at feeds, housing for groups, cow comfort, and diets. His webinar can be viewed at https://agmodelsystems.com/the-nutritionist-2021-webinar-scothorn-november/ 

We have Dr Tylutki, AMTS CEO, back for a farm walk of the heifer facilities on the same farm that we have toured last fall and in February of this past year. Tom introduces the concept of looking at diets from the aspect of those that are Biologically Optimal, Environmentally Optimal, and Financially Optimal. As before he referenced past blog posts, the links for which are: Nutrition Tools: Heifers, Nutrition Tools: Dry Cows, Nutrition Tools: Lactating Cows.
