Course Description
An animal nutrition course that integrates the principles of nutrient metabolism and bioenergetics with feed composition and chemistry across farm animal and laboratory species. Laboratory sections include gastrointestinal tract dissections, ingredient evaluation, ration formulation and production, and nutritional animal experiments.
