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.

The Next Mile, host Dr. Meredith Petersen, Director of Swine Health at the National Pork Board, sits down with Dr. Cara Haden, Director of Animal Welfare and Biosecurity at Pipestone, to unpack the National Swine Health Strategy and what it means for producers across the country.

Meredith walks through how the strategy came together: a producer-led effort launched in March 2025 in response to input gathered at the National Pork Industry Forum, built around two core goals, keeping foreign and emerging diseases out of the U.S. herd and reducing the impact of domestic diseases already here, including long-term elimination targets for PRRSV and PEDV.

Cara then brings the conversation down to the farm level, sharing how Pipestone scores biosecurity across seven key areas: air, feed, water, people, supplies, trucks and pigs, plus everything within the farm perimeter. She and Meredith dig into why farm leadership and daily culture, not just protocols on paper, ultimately determine whether biosecurity efforts stick.

Whether you're a producer, veterinarian, or anyone invested in herd health, this episode offers a grounded look at where the industry is headed and what everyday habits make the biggest difference.
