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: How Data Predicts Swine Outbreaks - Swaminathan Jayaraman

In this episode of The Swine it Podcast Show Canada, Swaminathan Jayaraman, Research Assistant and PhD Candidate at Iowa State University College of Veterinary Medicine, explains how integrated data systems can improve disease surveillance in swine production. He discusses combining diagnostics, animal movement data, production records, and spatial analytics to identify risks earlier and support proactive decision-making for PRRS, PED, and swine influenza. Listen now on all major platforms!

"Disease surveillance remains largely reactive because outbreaks are often confirmed only after transmission has already occurred across multiple connected production sites."

Meet the guest: Swaminathan Jayaraman / swamjay is a Graduate Research Assistant at Iowa State University College of Veterinary Medicine. With academic training in management information systems and engineering, he focuses on integrating diagnostic, production, and movement data to improve disease surveillance and decision support in swine production systems.
