In this episode of The Swine it Podcast Show, Dr. Neil DeBuse from Kalmbach Feeds and Dr. Steve Tousignant from Vaxxinova US discuss PRRS management strategies, recombination risks, whole genome sequencing, and the role of autogenous immunization programs in swine systems. They highlight practical approaches to improving immunity, reducing outbreaks, and advancing PRRS control across production systems. Listen now on all major platforms!

"Being PRRS negative sooner is a real key for eradication because every additional positive week increases production losses and viral exposure risks." - Dr. Neil DeBuse

Meet the guests:

Dr. Neil DeBuse is a veterinarian at Kalmbach Feeds with more than 30 years of experience in swine health and production. His work focuses on PRRS control, biosecurity, immunity, and improving production stability across commercial swine systems in the United States and internationally.

Dr. Steve Tousignant is Director of the Swine Business Unit and Technical Services Veterinarian at Vaxxinova US, with a DVM and PhD from the University of Minnesota. His experience combines epidemiology, technical services, and practical immunization strategies designed to support consistent herd performance and long-term production stability.

In this episode of The Swine it Podcast Show, as producers prepare for rising temperatures and seasonal heat stress challenges, Dr. Jay Johnson from the University of Missouri explains how genomic selection can support thermal tolerance in pigs without sacrificing productivity and become part of a broader strategy to improve performance and support animal welfare. He discusses why body temperature alone can be misleading, how heat loss capacity helps identify more resilient pigs, and why gestational heat stress can affect offspring performance long after birth. Listen now on all major platforms!

"Selecting for heat loss capacity can identify pigs with a reduced rate of body temperature increase as environmental conditions tend to go up."

Meet the guest: Dr. Jay Johnson is an Associate Professor of Animal Welfare and Stress Physiology at the University of Missouri. His work integrates stress physiology, nutritional physiology, and applied ethology to improve livestock welfare and productivity under challenging environmental conditions.
