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.
