While Dr. Jardon only had milk in his glass for this pubcast, he did share about his bottle of “wheyskey” (whiskey made from whey) from Wheyward Spirit Distillery in California (https://www.wheywardspirit.com/). Iowa State Dairy Extension is offering a webinar, “Fermentation and Distillation of Whey to Produce Spirits at Copper Crow,” on May 15 at noon Central. Curtis Basina of Copper Crow Distillery in Bayfield, WI, will be the speaker. You can sign up for the webinar at https://go.iastate.edu/WHEY (4:13)

Dr. Dhuyvetter presented a March 5 webinar on dairy economics, which can be found at balch...

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 cobalt EDTA. It’s common to use an oral dose of chromium EDTA as a marker to measure total tract permeability. Claire’s work, using cannulated cows, used a ruminal...

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 of lactation and subsequent production. (7:34)

The team chose to use the first 90 days of production as their production measurement to make sure they had as many cows as...

Dr. Zimmerman begins with an overview of Balchem’s microencapsulation technologies in both human nutrition and health and animal nutrition and health businesses. (0:31)

Encapsulation is a generic term, and huge differences can exist between products that protect the same compound. Balchem’s microencapsulation technology consists of packaging a substance in a lipi...

This episode is from a webinar presented by Dr. Sandra Godden from the University of Minnesota Department of Veterinary Population Medicine. To view the full webinar and access the slides referenced during this podcast, visit balchem.com/real science and scroll down to the webinar presented on November 8, 2023.

Dr. Godden begins with the reminder that despite decades of research and definite advances in colostrum management, there's still a lot to learn and research. Her goal is to give an update on new findings that can be utilized in your colostrum management program. (0:21)

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 meta-analysis included dry matter intake, milk production, milk composition, and milk component yields. The researchers also calculated the efficiency of utilization of histidine and other amino acids supplied to the cow by the diets. Lastly, they calculated marginal recovery of...

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)

There were 24 cows per treatment, and it was a continuous study rather than a Latin Square design. No differences were observed in...

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...

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

Our day two episode opens with Dr. Eric Ciappio and Dr. Jonathan Bortz of Balchem, summarizing day one’s focus on pregnancy and early life and previewing day two’s focus on the latest choline research targeting adult nutrition. (1:03)

The next guest on our roster is Dr. Mark Manary, a professor of pediatrics at the Washington University School of Medicine. Mark’s symposium talk discusses choline and food aid. Food aid products are spec...
