Show Notes
In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Lance Baumgard, Distinguished Professor at Iowa State University, explains how stress affects gut barrier function and dairy cow productivity. He highlights how immune activation redirects nutrients away from milk synthesis and discusses key stressors like heat, overcrowding, and transition periods. Learn how stacked stressors amplify biological responses and impact performance. Listen now on all major platforms!
"Stress across production systems consistently disrupts gut barrier integrity, allowing harmful compounds to cross into circulation and initiate immune responses that directly reduce dairy cow performance."
Meet the guest: Dr. Lance Baumgard is a Distinguished Professor and Norman L. Jacobson Endowed Professor in Dairy Nutrition at Iowa State University. His research focuses on stress physiology, gut health, and nutrient partitioning in dairy cattle, helping advance understanding of how stress impacts productivity and biological function.

Every productive dairy starts with the decisions farmers make each day. As we celebrate National Farmers Day this month, The Dairy Nutrition Blackbelt Podcast welcomes Dr. Jorge Barrientos Blanco, Dairy Nutritionist at Progressive Dairy Solutions, to explain how feeding accuracy, forage sampling, mixer performance, feed delivery, and cow grouping help match nutrient supply with cow requirements. Celebrate the work behind efficient, sustainable, and profitable dairy production. Listen now on all major platforms!
In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Andres Contreras, Professor at Michigan State University, explains how adipose tissue supports dairy cows during negative energy balance. He discusses omega-3 fatty acids, inflammation, insulin sensitivity, fatty acid mobilization, and the differences among fish, algae, and canola sources. Learn why selecting the right fatty acid source can help transition cows manage circulating fatty acids more efficiently. Listen now on all major platforms!
In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Alexander Hristov, Distinguished Professor of Dairy Nutrition at Penn State, discusses rumen methane formation and practical mitigation strategies for dairy cattle. He explains how fiber, starch, diet formulation, and feed additives influence hydrogen flow in the rumen, why production trade-offs matter, and why producers should evaluate methane-reduction claims through independent science.
