          UNIT GOAL:
          Students shall develop an understanding of the factors involved
          in animal nutrition, animal feeding, and the basic feedstuffs
          available for that purpose.


          UNIT OBJECTIVES: Upon completion of this unit, the students will be

          able to:

          1. List the six classes of nutrients and
             identify examples of feeds containing each.

          2. Have a basic understanding of the function of each
             nutrient needed by livestock.

          3. Identify samples of concentrates and roughages;
             compare the energy, nutrients and bulk supplied by each,
             and list sources of both.

          4. Develop an understanding of the chemical composition
             and classification of feeds.

          5. List contributions of microbial digestion
             (in ruminants) to the host, including synthesis of
             amino acids and B-vitamins.

          6. Develop an understanding of how feeds are digested and
             absorbed in the animal's body.

          7. Develop an appreciation for the importance of feeding
             regimes in animal management.

          8. Develop an understanding of the digestive systems in
             ruminants and non-ruminants, and how each contributes
             to digestion.

          9. Trace the pathway of breakdown and identify the organs
             involved in digestion of carbohydrates, fats and
             proteins in the monogastric system.

         10. Develop an understanding of the amount and kind of
             protein needed in feeding livestock.

         11. Develop an understanding of the classes and sources of
             carbohydrates needed by livestock.

         12. Develop an understanding of the use of fats in livestock
             feeding.
