Beyond the Cresty Neck: What Horse Owners Should Know About EMS

Presented by Callum Donnelly BVSc PhD DACT DACVIM (LAIM)

Why do some horses seem to gain weight just by looking at grass, while others struggle with serious metabolic problems despite careful management? This seminar will explore the science behind equine metabolic syndrome (EMS), explaining how insulin dysregulation contributes to obesity, laminitis, and other health concerns. We will discuss how to recognize horses at risk, understand diagnostic testing, and apply practical strategies for nutrition, exercise, and long-term management. Drawing on current research, the seminar will help horse owners separate common misconceptions from scientific evidence and make informed decisions to keep their horses healthy.

Dr. Callum Donnelly is an Assistant Professor of Theriogenology at Cornell University’s College of Veterinary Medicine, where he leads a research program exploring the complex relationships between metabolism, reproduction, and early-life development in horses. His research focuses on understanding how insulin regulation, reproductive hormones, and bile acid signaling influence metabolic health, fertility, and pregnancy outcomes. By studying both metabolic disease, including equine metabolic syndrome, and the unique physiological adaptations of healthy pregnancy, his laboratory seeks to uncover mechanisms that protect against metabolic dysfunction and identify new approaches to improving equine health and reproductive performance.
