Susan K. Duckett is currently a Professor in the Department of Animal and Veterinary Sciences at Clemson University where she holds The Ernest L. Corley, Jr. Trustees Endowed Chair. She received her B.S. degree in Animal Science from Iowa State University, and M.S. and Ph.D. degrees in Animal Science from Oklahoma State University. She held faculty positions at the University of Idaho and University of Georgia prior to her appointment at Clemson University. Dr. Duckett’s research integrates ruminant nutrition and meat science to alter lipid metabolism, fatty acid composition and palatability of animal products.
My research integrates ruminant nutrition and meat science to alter lipid metabolism, fatty acid composition and palatability of animal products. Current research projects include:
Impact of Fescue Toxicosis on Fetal Development and Postnatal Growth (USDA-NIFA)
Early exposure of steers to corn grain to enhance marbling deposition
Palmitoleic acid supplementation on lipid and glucose metabolism in obese sheep
