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: Feeding Faba Bean to Pigs - Dr. Eduardo Beltranena

In this special rerun episode of The Swine it Podcast Show Canada, Dr. Eduardo Beltranena from North Carolina State University explains how faba beans can be used in pig diets as a source of both starch and protein. He discusses environmental benefits, inclusion rates, frost-damaged beans, tannin concerns, cultivar selection, and how producers can compare faba beans against cereals and protein meals for cost-effective feeding. Listen now on all major platforms!

"Faba beans provide both starch and protein, competing directly with cereals in swine diets."
