Thomas D. Crenshaw is a Professor in the Department of Animal and Dairy Sciences with an affiliation with the Interdepartmental Graduate Program in Nutritional Sciences. His primary research emphasis is animal nutrition. Crenshaw received a Ph.D. (1980) and M.S. (1977) degrees at the University of Nebraska in swine nutrition and a B.S. (1974) degree in Animal Sciences at the University of Tennessee-Martin.
Swine nutrition is Crenshaw’s primary area of expertise. Throughout his research career, two primary research themes have focused on nutritional factors that enhance bone integrity and the cation-anion balance of mineral elements. These research efforts have required integration of biochemical, physiological, and cellular pathways, with inorganic chemistry, and mechanical engineering principles. Crenshaw’s research expertise has attracted strong interactions with researchers in academia and the commercial swine nutrition industry. His expertise in the use of swine as a biomedical model has allowed collaborations with researchers in mechanical engineering, orthopedic surgery, urology, human nutrition, and biochemistry. Additional major research efforts have included projects in amino acid nutrition and use of fatty acids as energy supplements to enhance neonatal pig survival.
Crenshaw has provided leadership for the U.W. Swine Research and Teaching Center throughout his career. The center supports practical agricultural research and basic swine biomedical research. This role has allowed contributions to research projects in nutrition, breeding and reproduction, gene editing, biomedical models, animal behavior, biosecurity requirements for animal health, housing and ventilation requirements, and surgical procedures.
Crenshaw has authored or co-authored 113 peer-reviewed publications, 41 conference proceedings and book chapters, and 36 extension publications.
