And it started like that. The snowball effect started gradually with one or two products, then the o...
Impact of Stocking Density on Milk Production and Profitability
January 23, 2024 15:00 - 24 minutes - 22.9 MBTimestamps & Summary Chris Gwyn (02:11) 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 wit...
Demystifying De Novo Fatty Acid Synthesis
January 09, 2024 15:00 - 21 minutes - 19.3 MBTimestamps & Summary Vicki Brisson (01:44) 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 ...
Cow-Calf Separation in Dairy Farming
December 12, 2023 15:00 - 32 minutes - 29.6 MBTimestamps & Summary Chris Gwyn (01:57) Animal welfare and perhaps its impacts on health are hot topics in the livestock industry today. Can you please share how you became interested in these topics? Dr. Marina Von Keyserlingk That started probably in my head, let's say 25 years ago. As you alluded to in the introduction, I did a Ph.D. in Animal Sciences and I was trained initially as an experimentalist and as a ruminant nutritionist. And I worked in the feed industry in a number of role...
Exploring Opportunities and Challenges in Dairy Beef Feeding Systems
November 28, 2023 15:00 - 29 minutes - 26.8 MBTimestamps & Summary Dr. Greg Eckerle (02:01) In your opinion, what can we expect to see numbers of dairy and dairy and beef crosses in feedlots in the future? Dr. Pedro Carvalho That's really a hot topic right now. I've been working with Holstein since I started grad school, and in the past few years, we've seen this increasing the utilization of beef semen in the dairy cows. […] There are a lot of factors that are affecting that. The increasing use of sex semen and the decrease in th...
Tools for Cow Handling at the Farm Level
November 14, 2023 15:00 - 16 minutes - 15.3 MBTimestamps & Summary Chris Gwyn (01:28) Can you explain what brought you to the study of cow handling specifically? Dr. Jennifer Van Os I started here at UW Madison about five and a half years ago, and as you mentioned, I'm in an applied research and extension outreach role. And so, I think it's really important that all the work that I do resonates with my dairy stakeholders. And so, when I was new, I went around and met with a number of Wisconsin dairy farmers and other people in the in...
Metabolism in Cattle for Muscle and Overall Development
October 31, 2023 14:00 - 29 minutes - 27 MBTimestamps & Summary Dr. Greg Eckerley (01:59) Looking at muscle development, what roles do we see coenzymes play in upregulating energy to help with growth? Dr. Bradley Johnson […] [the] energy needs for both postnatal muscle growth as well as the functionality of skeletal muscle that being contraction, we need a lot of ATP. And of course, we know that the coenzymes are going to assist with this. All the way from the shortest burst of energy that we're going to get to produce ATP an...
Understanding and Managing Gastrointestinal Tract Health in Cattle
October 17, 2023 14:00 - 24 minutes - 22.5 MBTimestamps & Summary Dr. Greg Eckerle (01:24) Do we normally call that intestinal acidosis outside of the agricultural university complex? Dr. Greg Penner I think probably the most common term that's used is hindgut acidosis rather than intestinal acidosis. And it probably makes sense given where we think most of that fermentation activity would occur and where the primary reduction in PH would be localized. Dr. Greg Eckerle (02:02) What can we do with the hindgut intestinal acidosis? An...
Let’s Talk About Meat!
October 03, 2023 14:00 - 10 minutes - 9.52 MBTimestamps and Summary 1:54 How do you feel about Meatless Monday? Jess Pryles I don’t feel much about Meatless Monday. It’s more of a fad […] 3:23 What can we be doing as an industry and as individuals, family-owned operations to impact our consumer demand more positively? Jess Pryles I think just telling the story, there are a lot of great social media platforms at the moment: Instagram, obviously big but particularly for AG, Tiktok has been extremely successful. There were a lot ...

[…] Vicki Brisson (04:28) What should [nutritionists] keep in mind when they’re formulating for indi...
Solutions to Navigate the Current Economy
September 05, 2023 14:00 - 20 minutes - 19.2 MBTimestamps & Summary Chris Gwyn (02:09) So John, in your work in advising agricultural businesses, and perhaps dairies in particular, talk to us about the strain that the current financial stressors of higher interest rates, softening milk prices and continuing high commodity prices cause at the farm level. John Ellsworth I think with inflation that we're fighting, not just in the US but Canada, everywhere, we have just higher-level inflation than we've seen for probably 40 years. And ...
Importance of Vitamins Stability in Premixes and Minerals
August 22, 2023 14:00 - 26 minutes - 24 MBTimestamps & Summary Dr. Greg Eckerle (01:34) Do we see an increase in interest in vitamin nutrition in cattle over the past years? And if so, what has sparked the resurgence of looking at vitamins again? Dr. Jason Warner When we think about cattle nutrition, I think it's certainly an area that we've seen some increased awareness and interest in the part of the industry over the last four to five years, particularly. And I think when you really take a look at it, that's really primarily d...
Transition Cow Health and Management
August 08, 2023 14:00 - 19 minutes - 18 MBTimestamps & Summary Vicky Brisson (01:33) Can you share with our audience what are the main diseases you observe and what the economic impacts of these diseases are? Dr. Jessica McArt As a dairy veterinarian, I see all sorts of diseases, and new ones every week, I feel. But the main diseases I see working on farms or with mastitis are early lactation diseases such as hypocalcemia, and hyperketonemia, also known as ketosis. We see a lot of retained placentas. We see cows with metritis, we...
How Mathematical Models Can Help Animal Nutrition
July 25, 2023 14:00 - 20 minutes - 19 MBTimestamps & Summary Vicky Brisson (02:20) In the last decade, modeling is a research method that's growing in popularity. However, mathematical modeling and livestock nutrition has been around for much longer than that. Can you explain models and what limitations they have? Dr. Jennifer Ellis A model can be anything from a single equation to a set of dozens or even thousands of equations, which represent, in our case, the behavior of a biological system. So, scientists will use models to...
Economic Situation and Perspective within the Cattle Market
July 11, 2023 14:00 - 28 minutes - 26 MBTimestamps and Summary Dr. Greg Eckerle (02:05) When we see where we’re at with the cattle cycle, where do you think the next three to five years of production are going to go? Dr. Lee Schulz Just to give a bit of background, the cattle inventory cycle has three phases. It has expansion, has liquidation, has a turnaround phase. We’re currently in the liquidation phase. This cattle cycle started in 2014, inventories peaked in 2019, and we’ve been on a slide of inventories over the last sev...

Vicky Brisson I was really lucky growing up on my family's dairy farm, because I grew up with plenty of excellent role models, whether that be my parents being involved in the community, strong women when I was involved in forage as well. But I'd say also growing up in the Francophone community in Eastern Ontario, it...
Mineral Recommendations in Dairy Cattle
February 15, 2023 15:00 - 22 minutes - 20.8 MBTimestamps & Summary 2:59 I was wondering if you could review some of the highlights for the audience to remind us of those key important areas. Dr. Bill Weiss For most minerals, what the committee tried to do is start at the cell. And we calculate, for example, how much mineral goes out and milk, how much mineral is free if an animal is growing, how much mineral is in that new tissue, and if she's pregnant, how much mineral is being deposited in the fetus, and we start there and we sum...
Rural Mental Health
