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 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. Aujo ..read more

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 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 economic ..read more

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 experimentalist and as a ruminant nutritionist. And I worked in the feed industry in a number of roles for over seven years. And during my time, sort of at the end of my PhD, and also working in ind ..read more

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 lot of factors that are affecting that. The increasing use of sex semen and the decrease in the beef cow herd, probably pushing that a lot. And I think it's something that came to stay. I ..read more

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 was new, I went around and met with a number of Wisconsin dairy farmers and other people in the industry to ask them what are the challenges they face when it comes to animal welfare on their far ..read more

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 this. All the way from the shortest burst of energy that we're going to get to produce ATP and muscle is the ATP-PC system, which is the phosphocreatine system, which within seconds ..read more

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 be localized. Dr. Greg Eckerle (02:02) What can we do with the hindgut intestinal acidosis? And how is that having an impact? Dr. Greg Penner First of all, one of the things we need to recogni ..read more

Timestamps and Summary     Vicki Brisson (01:56) Can you share more about the role and importance of amino acids to support the dairy industry’s sustainability initiatives? Dr. Izabelle Teixeira I think balancing for amino acids is really important and can play a very important role in improving sustainability and can be a way of leveraging nutrition to enhance their sustainability. […]   Vicki Brisson (04:28) What should [nutritionists] keep in mind when they’re formulating for individual amino acids? Or perhaps should they be looking at them as groups instead?   Dr. Izabe ..read more

Timestamps & 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 for our younger listeners, they probably never even experienced this before. And so, I was fairly y ..read more

Timestamps & Summary 01:33:00 – Why did you start researching B vitamins, a nutrient that was supposedly useless for the cow? And how did your original hypothesis change over the years? Dr. Girard started to think about B vitamins when she had to prepare a seminar and a review of literature during her PhD. Pregnant at the time and having to take folic acid supplement herself, she decided to conduct her review on folic acid supplement in mammals. She was surprised that there was really nothing about ruminants, especially in dairy cows.   When she started to work at Agriculture and Agri ..read more
