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.
