Research Examining Stress Hormone Levels in Hair Expected to Interest Breeding Companies

Apr 10, 2023

An international research effort which is looking at the potential of measuring hormone levels in the hair of pigs to identify genetic lines that will be less affected by stress is expected to be of particular interest to breeding companies.
Researchers with Iowa State University, the Universities of Saskatchewan and Alberta and CDPQ are collaborating on a project under which the levels of three stress hormones in the hair of pigs are being measured to evaluate the effect of stress on performance and on disease resilience.
Dr. Jack Dekkers, a distinguished professor in the Department of Animal Science at Iowa State University and the Principal Investigator, says, by correlating the levels of stress hormones in the hair to growth performance and disease resilience, it should be possible to identify genetic lines of pigs that will be more or less affected by stress.

Video: ASF Spread and Control Insights - Dr. Carles Vilalta

In this episode of The Swine it Podcast Show Canada, Dr. Carles Vilalta, epidemiologist at IRTA CReSA in Spain, explains the current African swine fever situation, including origin, transmission, and control strategies. He highlights the role of human activity, wild boar dynamics, and biosecurity measures to protect commercial farms. Learn how surveillance and field actions shape disease containment. Listen now on all major platforms!

"ASF demonstrates slow animal to animal transmission despite high infectivity, making it a clumsy disease that depends heavily on human mediated spread."
