Mary Beth Gordon, Ph.D.

Director of Equine Research and New Product Development

It’s extremely rewarding to me to develop products that I know can make a difference in horses.

Dr. Gordon’s work includes conducting research, analyzing data, scouting for new products, reformulating older products and working to improve the health of horses through nutrition.

“The work I do at Purina is my passion and education put together.  Conducting research and developing new products to help horses and their owners, while utilizing cutting edge technology and contributing to nutritional science is an amazing combination,” she said. “I’m grateful for the opportunity Purina provides to conduct this research, including the support of our equine research unit with our dedicated staff and budget allowance that makes all of it possible.”

Dr. Gordon’s research expertise and interest includes:

  • Appetite regulation and the palatability of feedstuffs
  • Exercise physiology
  • Obesity, metabolic syndrome and insulin resistance
  • Manufacturing research and its effects on biochemical response in horses
  • Reproduction and growing horse research
  • Senior horse research
  • Hydration in horses
  • Utilization of new forage technologies
  • Supplement development

Horsemanship is in her blood. Her grandparents were “horse people” and her grandmother took her to Dressage at Devon as a young girl to help fuel her passion.  She’s ridden since childhood and served as co-captain of the equestrian team and president of the equine club at Delaware Valley College. Today, she’s active in the sport horse world as a dressage rider.

During her doctoral education at Rutgers University, her research in equine nutrition and exercise physiology focused on the effects of exercise on hormonal regulation of appetite in horses. She’s been published in scientific journals including The Veterinary Journal, Journal of Animal Science and Equine Comparative Exercise Physiology and has coauthored chapters in several equine textbooks. Additionally, her work was the first to characterize the appetite stimulating hormone ghrelin in horses.
