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: Optimizing Piglet Gut Health for Performance - Dr. Marco de Mik

In this episode of The Swine Nutrition Blackbelt Podcast, we revisit a conversation with Dr. Marco de Mik, Senior Consultant at Schothorst Feed Research, who explores how to enhance gastrointestinal health in piglets for optimal growth. He shares his expertise on how feed formulation, stomach function, and gastrointestinal health directly impact the pig’s growth and development. Learn how to balance nutrient absorption, reduce diarrhea risks, and optimize feed performance. Tune in on all major platforms!

"The stomach is the first barrier to kill bacteria, and it’s crucial for storage, digestion, and antibacterial functions. All of these contribute to overall gastrointestinal health."

Meet the guest: Dr. Marco de Mik / mdemik holds a veterinary medicine degree from Utrecht University and an M.Sc. in Animal Nutrition from Wageningen University. With over a decade of experience in swine nutrition, he currently works as a Senior Consultant at Schothorst Feed Research. He specializes in feed formulation, animal physiology, and metabolism.
