Our overall research objective has been to develop an enlightened, integrated understanding of visceral nutrient metabolism and its impact on nutrient availability and production in dairy and beef cattle. The major focus has been the effect of nutrient supply on the metabolic and endocrine processes determining nutrient utilization for milk and meat production and food composition. Recent themes include the utilization of essential and nonessential amino acids for milk protein synthesis, the effects of site of starch digestion on nutrient absorption and metabolism in lactating dairy cows, the metabolism of hypophagic gut peptides in dairy cows, and the role of the gut and liver in coordinating nutrient supply in ruminants. Applied studies have addressed the nutritional management of transition dairy cows and subsequent effects on reproduction. More recent efforts, in conjunction with colleagues in human nutrition and food science, have focused on the manipulation of milk fatty acid composition towards current nutritional guidelines for reducing cardiovascular disease and increased content of neutraceutical fatty acids, the effects of those manipulations on consumer acceptability of dairy products, and the effects of specific conjugated linoleic acid isomers on human health.
