The Swine Nutrition Blackbelt Podcast - Dr. Sam Gerrard: Nutrient Utilization During an Immune Challenge | Ep. 205

the swine nutrition blackbelt podcast Jan 08, 2026

In this special rerun episode of The Swine Nutrition Blackbelt Podcast, Dr. Sam Gerrard, postdoctoral fellow at Virginia Tech, breaks down how immune challenges shift nutrient use in pigs and impact performance. The conversation covers reduced feed intake, immune-driven nutrient diversion, and how pair feeding models help separate disease effects from intake effects. Dr. Gerrard explains why understanding physiology during health challenges is critical for maintaining feed efficiency and animal welfare. Listen now on all major platforms.

What you'll learn:   

  • Swine immune response
  • Feed intake changes
  • Pair-feeding models
  • Bacterial vs. viral impact
  • Nutrient-use efficiency

 

Meet the guest:

Dr. Sam Gerrard holds a DVM and a PhD in Nutritional Physiology and is a postdoctoral fellow in the Department of Human Nutrition, Foods, and Exercise at Virginia Tech. His work focuses on swine physiology, immune challenges, and nutrient allocation during disease.
