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 bal ..read more

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 d ..read more

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) Promoting calf h ..read more

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 utilizatio ..read more

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 a ..read more

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 specially designed ..read more

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) The experiment was designed as a factorial with four treatments combi ..read more

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 the high fertility cycle starts with a change in body condition. Observations from the late 1980s and early 1990s showed that cows who calved at a higher bod ..read more
