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

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.

FLEECED! Sheep Shearer Hands Over Clippers!

Video: FLEECED! Sheep Shearer Hands Over Clippers!

It's sheep shearing day at Ewetopia Farms! ?? Our Dorset lambs and ewes are getting fleeced — and for the first time, our shearer hands over his clippers to a beginner. We finish shearing the last of our adult ewes and this year’s Dorset ewe lambs.

From moving the sheep between barns, loading them into chutes, and watching the wool come off, this is always one of the most satisfying days on the farm. But this video has a twist — we welcomed a new helper, Gian, who’s not only lending a hand but also learning how to shear! With guidance from our experienced shearer, he got a crash course in sheep shearing and even tried his hand at shearing a couple of lambs himself.

You’ll see firsthand how both teacher and student handled this unique challenge. Shearing is more than just removing wool — it’s about sheep health, comfort, and giving us a closer look at the flock. It’s always amazing to see the transformation from woolly sheep to freshly shorn ewes and lambs.
