Principles of Animal Nutrition - From Fundamentals to Feeding

Principles of Animal Nutrition deals with classification and function of nutrients, deficiency symptoms, digestive processes, characterization of feedstuffs, and formulation of diets for domestic animals.

In this single course, learn all aspects of nutrition for domestic animals, from fundamentals of nutrition through feeds and feeding. The principles apply to all mammalian and avian species, but there will be an emphasis on swine, beef cattle, dairy cattle, poultry and horses. Feeds most commonly used in the United States will be emphasized, but feeds and principles of their use that are important to animals throughout the world will be considered.

Prerequisite Requirement for Vet School

Principles of Animal Nutrition meets the background requirement for application to colleges of Veterinary Medicine requiring animal nutrition (please check your school of interest to confirm).

Textbook Information: Church, Pond, and Schoknecht. Basic Animal Nutrition and Feeding. (Highly recommended)
