Equine hormone baseline study

WCVM researchers are seeking client-owned healthy horses as well as horses diagnosed with pituitary pars intermedia dysfunction (PPID) for a hormone baseline study.

WCVM researchers are conducting a collaborative study with Prairie Diagnostic Services (PDS), Saskatchewan’s provincial veterinary diagnostic laboratory. Once published, the study’s results will help to establish reference values for hormones that accurately reflect the horse population in Canada’s western provinces.

WCVM clinicians will collect blood samples from at least 40 client-owned healthy horses and from 20 or more horses diagnosed with PPID. The team will collect these samples during farm visits by the WCVM’s Equine Field Service or during regular appointments at the WCVM Veterinary Medical Centre.

Horses recruited for the study will be sampled once for insulin and T4 — measurements required for EMS diagnosis or diagnosis of thyroid disorders. The WCVM team will also collect samples for the hormone ACTH, which is an essential measurement for diagnosing PPID. Since normal ACTH values can vary by season, WCVM researchers will collect samples from the study’s horses in the spring and fall — about five months apart.

WCVM veterinarians will provide owners with their respective test results free of charge, along with a written report about their findings and recommendations. Owners can request further testing or therapies for their horses, but they will be responsible for any additional fees.
