Extension ProgramsSome of my extension areas of
interest include providing nutritional information for the average horse
owner as well as the racehorse owner/trainer. I also aim to improve pasture
quality in the state of New Jersey and surrounding areas through better
pasture management. The bigger picture is to help promote the horse industry
in NJ to people throughout the state. The primary goal of my research lies in equine nutrition and specifically
how it affects the performance of the equine athlete. Currently I am focusing
on decreasing oxidative stress, muscle membrane leakage, and improving
antioxidant status of exercising horses using various antioxidant supplements.
In the past I have worked with competing endurance horses, and more recently
at Rutgers I have started working with the Standardbred racehorse. American Society of Animal Science
