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: Learning to Wrench From Dad the Hard Way

Harvest is a week out and the farm picked this week to fall apart. The truck needs a battery, the barn curtain's got a problem, and the corn and beans are telling us we're out of time to get it all fixed.

So it's a full day of wrenching. Tork supervises while I get the truck back running, then we're out at the hog barn where one rusted up part has the whole curtain system hung up. Ladder work, cable work, and a little dad-and-son disagreement about the right way to do it. We close it out walking the fields, shelling beans and checking corn, because whether everything's fixed or not, harvest starts when harvest starts.
