The Dairy Nutrition Blackbelt Podcast

In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Richard Paratte, dairy nutritionist at Vetagro, explains how lysine drives milk production efficiency beyond crude protein. He explores amino acid balance, rumen protection technologies, and how precision delivery improves milk protein and fat synthesis. Get practical insights on microencapsulation and metabolic coordination to improve performance. Listen now on all major platforms!

"Dairy cow performance depends on amino acid balance rather than crude protein levels, since limiting amino acids like lysine directly influence milk protein synthesis efficiency and overall nutrient utilization."

Meet the guest: Dr. Richard Paratte earned a PhD in Animal Science and has over 20 years of global experience in ruminant nutrition and agribusiness. As a dairy nutritionist and specialist in precision nutrition and microencapsulation, his work focuses on improving efficiency, animal health, and sustainability in dairy systems.

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.
