Timestamps & Summary   Chris Gwyn ( 01:35 ) How would you describe the current state of lameness on dairy farms, and how has it evolved over your career? Dr. Gerard Cramer I started working on lameness when I started my graduate work in 2003. Things have progressed, but I think it's still probably one of the major animal welfare issues in the industry. So, I'd say we probably haven't progressed as...

Timestamps & Summary  Chris Gwyn (02:58) How should nutritionists use lab data to confirm that what’s formulated on paper matches what cows are actually eating and performing? Katie Raver A lot of times when we get a feed analysis, we use those feed analysis to formulate our ration. So we'll pull those into a model and build a ration around those. […] But I think there's a lot of value beyond that...

Timestamps & Summary  Chris Gwyn ( 02:04 ) Could you share with the audience why B vitamins would be important to receiving cattle in particular? Dr. Stephanie Hansen Absolutely. If we go back and look at the NRC guidelines, we've really ignored two classes of vitamins, vitamin C and vitamin B. Cattle are able to make vitamin C from glucose in their liver. […] Not a lot of work is focused on that...

Timestamps & Summary    Chris Gwyn ( 01:44 ) Before we jump right in, I'd enjoy hearing about the journey that brings you to research and teaching. Dr. Stephanie Hansen  I did not grow up on a beef operation, but my grandparents had cattle, and so I spent a lot of summers there.

Timestamps & Summary    Chris Gwyn ( 01:50 ) Dr. Hernández, could you share with the audience your journey that brought you to be a trusted researcher and advisor at the University of Wisconsin? Dr. Laura Hernandez Sure. Working in Dr. Collier's lab, I had the fortunate pleasure of working in mammary biology. I specifically worked on how the mammary gland interacts with the endocrine and metabolic...

Timestamps & Summary   Chris Gwyn (02:26) 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 po...

Timestamps & Summary  Chris Gwyn ( 01:51 ) 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 thin...

Timestamps & Summary  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 t...

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...

Timestamps & Summary   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...

Timestamps & Summary  Chris Gwyn ( 02:05 ) 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...

Chapitrage et résumé   Vicky Brisson ( 01:54 ) 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 s...

Timestamps & 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 ar...

Timestamps & 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...

Timestamps & 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 expe...

Timestamps & 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...

Timestamps & 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 wa...

Timestamps & 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...

Timestamps & 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...

Timestamps 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, obviou...
