Genetics Can Boost Swine Herd Health

    Herd health is a constant worry for pork producers, especially with increasing restrictions on the use of antibiotics and other preventative treatments. Recent improvements in biosecurity practices can help, of course, but breeding for disease resilience offers a vital, complementary approach.

“Genetic improvement can be an important component in a comprehensive strategy to combat the impacts of disease,” says Jack C. M. Dekkers, Ph.D., a C.F. Curtiss Distinguished Professor in the Department of Animal Science at Iowa State University. “How pigs respond to disease has a substantial genetic component and can, thus, be selected for. While resistance to some diseases is determined by a single gene, resistance to most diseases is controlled by many genes and is not complete.”

Measuring Resilience

In his upcoming talk at United Pork Americas in Orlando, Fla. (Sept. 7-9, 2022), Dekkers will discuss how and why genetics can play a critical role in lessening the impact of disease on pork production. “An understanding of the genetic basis of resistance and resilience of disease will help producers determine the best sources of genetics for their operations,” Dekkers says.

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.
