Dr. Sarah Ralston, PhD, VMD, Professor Emeritus, is board certified by the American College of Veterinary Nutrition. She retired from the Department of Animal Sciences at Rutgers University July 1, 2017, after 28 years of teaching, research and outreach, but is continuing to write articles, consult and lecture on topics related to equine nutrition. Her primary research focus throughout her career has been on the effect of rations on glucose and insulin metabolism in horses, but since 2001 she has been using metabonomic multivariate analyses of Nuclear Magnetic Resonance (NMR) spectra of blood from young horses in collaboration with Dr. István Pelczer of Princeton University and researchers in Australia, Germany and Brazil to detect metabolic abnormalities associated with the development of osteochondrosis dessicans. This research has led to the development of rations that will hopefully reduce the risk of developmental orthopedic disease in genetically predisposed foals (Patent pending). Previously research focused on metabolism and nutrient requirements of geriatric horses, which was in part responsible for the formulation of "senior" feeds for failing old horses. Another on-going research interest is the effect of prolonged transport on immune function in horses and dietary supplements (ie. vitamins C and E) that might reduce the incidence of infectious diseases in horses transported long distances. She dabbled in the use of hair mineral analyses in horses in collaboration with Ray Leroy of Accutrace laboratories in the 1980’s.
