Animal Digestion

This comprehensive guide explores the essential nutrients necessary for animal health, including carbohydrates, fats, proteins, vitamins, minerals, and water. It distinguishes between ruminants, such as cows and sheep, and non-ruminants like pigs and poultry, emphasizing their unique digestive systems and feeding requirements. Learn about energy sources in animal diets, the importance of protein, the role of minerals and vitamins, and the use of additives in livestock feeding. This information is crucial for optimizing animal growth, maintenance, and overall body functions.

Presentation Transcript

  1. Animal Digestion

  2. What are Nutrients? • parts of food which provide for growth, maintenance, body functions • Carbohydrates (CHO) • Fats • Proteins • Vitamins • Minerals • Water

  3. What is a Ruminant? • Animals with more than one compartment in their stomach • Chew their cud (re-chew food) • Cows, sheep, goats • Cows have four compartments in their stomachs

  4. NonRuminants • Foragers: Horse, rabbit • NonForagers: pig, poultry

  5. How much to feed? • Depends on function of animal • Pregnant, Lactating, Working, Growing • How often to feed Depends on stomach size & rate of metabolism Stomach size is relevant to amount of feed fed

  6. What foods give energy? • Carbohydrates (starch & cellulose) & Fats • Fat = 2 1/2 times energy of CHO • Energy is major part of a feed ration • Up to 90% of a ration for a steer • Measured in Kilocalories or TDN (Total Digestible Nutrients)

  7. What are Proteins? • Used to build muscle, body tissue • Made of amino acids • Ruminants can make some proteins • Simple Stomachs need specific amino acids

  8. What are Minerals? • Natural elements which regulate certain body functions • Na, Ca, P, Fe, Cu, K, Mn, Mg, Zn, Mo, Se, I, Co • Most are trace minerals

  9. What are vitamins? • Compounds responsible for certain functions • Fat Soluable = A, D, E, K • Water Soluable = B, C

  10. What are additives? • Antibiotics: disease prevention • Coccidiostats: control parasites • Xanthophyll: makes egg yolks yellow • Hormones: increase growth • Tranquilizers: calm nerves (cattle, turkeys) • Antioxidants: prevent feed from getting rancid • Pellet Binders: keep in pellet form • Flavoring Agents: make taste better

  11. Livestock Feeding • Roughage = high fiber, low energy • Concentrate = low fiber, high energy
