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: Synthetic Microbiota Explained - Dr. Alexandre Thibodeau

In this episode of The Swine it Podcast Show Canada, Dr. Alexandre Thibodeau, from the University of Montreal, explains how synthetic microbiota and bioreactor systems can help researchers study gut microorganisms, evaluate feed additives, investigate Salmonella control strategies, and develop alternatives to animal trials. Listen now on all major platforms!

"Bioreactor models can screen microbiota solutions before animal trials, lowering costs and reducing the number of pigs needed."

Meet the guest: Dr. Alexandre Thibodeau / alexandre-thibodeau-2493a540 is an Associate Professor at the University of Montreal, in Canada, with a PhD in Veterinary Science and Microbiology. His work focuses on swine gut health, food safety, microbiota research, pathogen control, and alternative research models that support animal production and welfare. His research explores innovative strategies to better understand interactions among microorganisms and to improve livestock health outcomes.
