Unlocking the Role of B Vitamins in Receiving Cattle

RumiNation ·

2025/10/21

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 HansenAbsolutely. 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 because the assumption has been that the animal can make it, it's fine. Similarly, they get most of their B

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. So, I had the beef bug, so to speak, by the time I went to undergrad at Iowa State, but I was never pre-vet. I was really focused on what we could do, and eventually I realized that what that was was nutrition to actually keep

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 DannI 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

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.

RumiNation ·

2024/01/09

Timestamps & Summary Vicki Brisson (01:44)As an introduction, can you explain what de novo fatty acid synthesis is?Dr. Débora SantschiTo 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

Timestamps & Summary Dr. Greg Eckerle (01:24)Do we normally call that intestinal acidosis outside of the agricultural university complex?Dr. Greg PennerI 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
