Dr. Lance Baumgard joined the U of A faculty in 2001 after completing his doctorate work at Cornell University. Dr. Baumgard's research focuses on nutritional physiology and metabolism primarily in dairy cattle. He also organizes the Southwest Nutrition Conference each spring. The conference is recognized as one of the largest gatherings of west coast dairy and beef nutritionists, consultants, academics, and veterinarians. It is a great opportunity to learn more about cutting edge research with regards to cattle nutrition, metabolism and management as well as a chance to network with key personnel in the west coast dairy and beef industry.
Research Interests:
Research focus will be on improving efficiency of animal production and to better understand how nutrient utilization is regulated. Of special interest is how homeostatic and homeorhetic systems control nutrient partitioning to support different physiological states. Areas of research will involve nutritional, biochemical, molecular, and endocrine aspects of metabolism.
Lactation: Research will concentrate on mechanisms regulating milk synthesis and production of milk components. This will involve studying the process of how milk fat is synthesized and how environmental factors, including nutrition and ambient temperature, regulate both the yield and composition of milk fat. Goals are to discover techniques to manipulate milk fat production to improve animal performance and well-being and improve the healthfulness of dairy products. Continued efforts will be made to identify the biological mechanisms by which selection mediates increased milk yield and to understand the variation and improve the efficiency of milk production.
Growth: Research will focus on understanding lipid metabolism during growth. This will involve studying the process of how nutrients are coordinated and partitioned between accretion of lean and adipose tissue. Efforts will be made to manipulate lipid metabolism to improve efficiency and healthfulness of animal products.
