Research disciplines include environmental nutrition, molecular nutrition, Nutritional Physiology, Animal Production Systems, Nutritional Biochemistry, Applied Animal Nutrition.  The research ranges from the very applied problems in animal growth to highly fundamental scientific questions of animal growth, production, and health. Research, education, and extension programs in Animal Nutrition currently concentrate on beef cattle, dairy cattle, swine, poultry, and sheep in the following disciplines.


Lance BaumgardDr. Lance Baumgard

Dr. Baumgard's lab researches nutritional and environmental physiology of dairy cattle, with specific interests in how immune activation disrupts optimal productivity.



Stephanie HansenDr. Stephanie Hansen

Dr. Hansen's research focuses on molecular and applied ruminant nutrition. The Molecular Ruminant Nutrition aspects include mineral metabolism, meat quality and biological mechanisms explaining differences in feed efficiency.  The applied ruminant nutrition points include minimizing feed costs, the impact of nutrition and management on climate change, ethanol co-products in cattle diets, preparing cattle for the feedlot and timely topics.  

Laura GreinerDr. Laura Greiner

Dr. Greiner will be focusing on the impact of various aspects of nutrition, health, and production on sow reproduction and piglet health.
