In this episode of The Swine it Podcast Show Canada, Dr. Joshua Selsby from Iowa State University explains how heat stress affects swine biology and why now is the ideal time to prepare for next summer’s challenges. He breaks down its effects on muscle function, immune responses, and long-term metabolic outcomes. Learn how early planning can protect herd performance when temperatures rise again. Listen now on all major platforms!

"Heat stress leads to a cascade of biological damage, beginning with metabolic disruption and expanding across multiple organ systems."

Meet the guest: Dr. Joshua Selsby is a Professor in the Department of Animal Science at Iowa State University. With over 15 years of research on skeletal muscle physiology and heat stress, he focuses on understanding how thermal stress disrupts swine metabolism, immune function, and muscle integrity.
