Guests: Dr. Bill Weiss, The Ohio State University; Dr. Helene Lapierre, Agriculture and Agri-Food Canada, Sherbrooke Research and Development Centre, Quebec; Dr. Susanna Räisänen, ETH Zurich 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)

Guests: Dr. Bill Weiss, The Ohio State University, and Dr. Alexander Hristov, Pennsylvania State University 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 extruded and thus exposed to heat. (7:02)

Guests: Dr. Sandra Godden, University of Minnesota College of Veterinary Medicine; Tricia Badillo, Shadycrest Holsteins 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 monitoring measures to assess a colostrum program. Research continues on the value of post-closure feeding of colostrum after the first 24 hours when the gut can no longer absorb antibodies. Several studies have demonstrated improved health, reduced scours, reduced bovine respiratory disease, reduced antibiotic use, and enhanced gain. Tricia gives an overview of their program, where they feed transition milk to their calves. (5:15)

Guests: Dr. Jonathan Bortz, Balchem Corporation; Dr. Mark Manary, Washington University School of Medicine; Dr. Rima Obeid, Saarland University Hospital; Dr. Susan Smith, University of North Carolina Nutrition Research Institute; Dr. Isis Trujillo-Gonzales & Dr. Evan Paules, University of North Carolina Nutrition Research Institute; Dr. Bryan White, University of Illinois; Dr. Julia Maeve Bonner, Sanofi; Dr. Stephen Hursting University of North Carolina Nutrition Research Institute Today’s episode was filmed at the Future Directions in Choline Symposium put on by the University of North Carolina Nutrition Research Institute.

Guests: Dr. Stephen Hursting & Dr. Susan Smith, University of North Carolina Nutrition Research Institute; Dr. Steven Zeisel, University of North Carolina; Dr. Kevin Klatt, University of California, Berkeley; Dr. Richard Canfield, Cornell University; Dr. Colin Carter, Columbia University; Dr. Joe McFadden, Cornell University

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 with the amylase-enhanced gene compared to the same hybrid without the genomic enhancement. (4:51)

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)

Our Real Science Exchange pubcast always has leading scientists and industry professionals discussing the latest ideas and trends, and tonight, we have two distinguished guests. Dr. Limin Kung and Bonni Kowalke join us to discuss wild yeasts in silage.

In this journal club episode, Dr. Alex Bach with the Catalan Institution for Research and Advanced Studies joins Dr. Bill Weiss from the Ohio State University.

In this episode, we welcome back the fan-favorite journal club podcast. Dr. Bill Weiss joins Scott and Clay for this episode, discussing a large study from Germany evaluating the time spent in the pre-fresh group and its impacts on health and production.
