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: CEOs of the Industry: John McIntire, Partner at Pike Pig Systems

CEOs of the Industry, Jim sits down with John McIntire, Partner at Pike Pig Systems, one of the most quietly impressive 26,000-sow operations in the U.S. John shares how he grew from operator to partner, how Pike built a people-first culture with long-tenured managers, and why they’re committed to weaning bigger, stronger pigs at 25+ days.

John breaks down how Pike stays efficient in a tough economic environment, the power of their shareholder-owned farm model, and how their work with PIC and a 240-head boar facility drives genetics and health outcomes. He also opens up about the innovations Pike adopts — and how they decide what’s truly valuable versus industry hype.

From Prop 12 and labor challenges to trade, consumer expectations, and sustainability, John chooses a hot-button issue and shares how Pike is preparing for the future. The episode closes with a rapid-fire “Fast Five” — mindset, leadership, daily habits, and three words that define Pike Pig Systems in 2025.

If you want a look inside a people-driven, purpose-driven, quietly elite pork system, this is an episode you won’t want to miss.
