Catalog Description:

In this course, students will learn the science of animal nutrition, including the functions of major nutrient classes and fundamentals of digestion and absorption in both ruminants and non-ruminants. The practical aspects of feeding livestock will also be covered, including evaluating nutrient needs of livestock, feedstuff evaluation, economics, and ration balancing. This class may include field trips.

COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1. Explain the fundamentals of digestion and absorption in both ruminants and non-ruminants.

2. Demonstrate the use of feedstuffs to meet the nutrients needs of various classes of animals.

 

Objectives:

At the conclusion of this course, the student should be able to:

 

1. Explain the role of nutrition in animal performance and food production.

2. Discuss the importance of the six basic nutrients in relation to growth and production.

3. Discuss how ruminants and non-ruminants utilize food stuffs.

4. Discuss how nutrition effects production, growth, and reproduction.

5. Identify accepted feeding practices.

6. Interpret National Research Council (NRC) tables and apply the relevant information to the formulation of livestock rations.

7. Collect and calculate data used in ration formulation.

8. Evaluate economic factors and trends in feeding.

9. Formulate rations with economic feasibility.

10. Identify various primary and by-product feeds, forms and processing techniques.

11. Formulate balanced rations for livestock.

12. Evaluate on-farm feeding practices and animal conditions to determine appropriate feeding strategies.
