Animal Nutrition

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.

John PatienceDr. John Patience

Energy is the most expensive component of the pig’s diet, so John’s research focuses on how to most economically supply that energy to the pig, and also to understand how the pig will utilize that energy, to produce the best performance, a high quality carcass while minimizing the impact on the environment and maximizing net income. With the recent changes in regulations surrounding the use of antibiotics in swine diets, John is also investigating ways to formulate diets that help the pig resist disease. Finally, John studies the use of enzymes in swine diets, to improve diet utilization, to improve health and performance and to minimize the environmental impact of pork production.

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.
