Dr. Penner describes two primary factors of gut health to be absorption and barrier function or permeability. His lab’s work on permeability is suggesting that intestinal regions really drive total gut permeability to a much greater extent than ruminal permeability in dairy cows. (7:06)

Ms. Bertens is Dr. Penner’s Ph.D. student and explains some new methodologies she developed for measuring gut permeability using chromium EDTA and c...

Guests: Dr. Bill Weiss, The Ohio State University; Dr. Marcia Endres, University of Minnesota

Dr. Endres begins with a description of a dataset she collected containing individual body weights from 34 robotic milking herds. Weights were collected for every cow; every time that she came into the robotic milking station. Dr. Endres’ team was interested in the relationship between the amount of body weight change in the first 21 days o...

Dr. Godden begins with the reminder that despite decades of research and definite advances in colostrum management, there's...

Dr. Räisänen completed this research during her Ph.D. at Penn State. The meta-analysis included 17 different studies published between 1999 and 2022 investigating supplemental histidine for lactating dairy cows. They divided the type of supplemental histidine between infused histidine and rumen-protected histidine and the basal diets between corn silage-based and grass silage-based. (4:34)

Primary response variables measured in the ...

Dr. Hristov started working with canola meal after he commissioned a review paper comparing canola and soybean meal when he was editor of the Canadian Journal of Animal Science. In that review, most of the studies used solvent-extracted soybean meal. Because canola has a higher oil content, it is always mechanically extruded to remove oil before solvent extraction. This paper is a more fair comparison because both meals were extrud...

Dr. Godden opens this episode with a 30,000-foot view of colostrum management. Colostrum management has been a hot topic for decades, and herds still have opportunities to improve. Researchers continue to learn how to advance colostrum management. The basics include the three Qs: quality, quantity, and quickness. Other critical factors are cleanliness and feeding clean colostrum. Dr. Godden also briefly discusses important monitori...

Today’s episode was filmed at the Future Directions in Choline Symposium put on by the University of North Carolina Nutrition Research Institute.

Kirby begins with a description of the mechanism of amylase-enhanced corn. The amylase is located in the kernel and, once activated by temperature change, works to increase the digestibility of the starch. A small amount of activation is thought to occur during silage fermentation, with further activation once it reaches the rumen. This paper evaluated digestibility and milk production in cows fed corn silage made from a hybrid wit...

Guests: Dr. Paul Fricke and PhD Candidate Megan Lauber, the University of Wisconsin-Madison

Dr. Fricke starts this episode by describing the long-term negative trend for reproductive performance in dairy cows that took place from the mid-1950s to around 2000. 

The reversal of this trend is due to the use of genomics to select for fertility and the use of synchronization and fertility programs in dairy cows. (6:07)

Dr. Fricke explains ...
