Principal Research Interest:
Dr. Grummer conducts research in lipid metabolism of dairy cattle. He investigates hepatic lipid metabolism, particularly as it relates to the etiology of lipid-related metabolic disorders such as fatty liver and ketosis. His laboratory is active in research to improve nutritional status of cows immediately prior to calving. He also studies the effects of supplemental fat on lactation and reproductive performance.
