Regardless of the investment we’ve made – if it doesn’t perform, it doesn’t go in the bag.

Dr. Davison supports the sales team and equine veterinarians through nutrition training and Professional Horse VIP meetings on the farm. She has been in the horse business her entire life.

“Some people feel that if we fed horses just like Mother Nature does, they wouldn’t have many of the health problems we encounter in our horses,” says Dr. Davison. “But not many of us have 25,000 acres of free-range pasture to graze. We’re asking horses to mature earlier, be bigger, live longer, carry us around and live in stalls or small paddocks. We’ve taken them so far from what Mother Nature developed them for the feed is the least of the things that isn’t natural. At Purina, we develop nutrition products to support the different types and levels of work they do and what Mother Nature alone just can’t support; all while being healthy and happy in the world they live in.”

Dr. Davison’s research expertise and interests include:

  • The use of higher fat diets for horses.
  • The effects of nutrition on equine reproduction, lactation and growth.
  • Nutritional support for top-level equine athletes.

“I am blessed to be able to earn a living doing what I love, studying equine nutrition and physiology. In my position with Purina I have been able to teach people what we currently know to be the best ways to feed horses. At the same time, I’m able to feed my curiosity and learn more by investigating new ways to feed horses better,” she says.

“If you’re a horse nutrition nerd like me, working for Purina is the best job there is. I have a personal stake in the performance of Purina products because we feed Purina to my family’s personal horses, along with our customers’ horses. We expect Purina to do the best job possible for our horses,” says Dr. Davison.

Dr. Davison grew up competing in American Quarter Horse Association shows and high school rodeos, and has shown in National Reined Cow Horse and National Reining Horse Association shows. She occasionally competes in barrel racing. Her husband trains cutting horses and western performance horses, and her children are accomplished competitors as well.

Dr. Davison holds a master’s and doctoral degree from Texas A&M University.
