Document Summary

Animal needs: carbohydrates: energy, fat, protein, minerals: inorganic, vitamins: organic compound. 1: monogastric with enlarged cecum (horse, monogastric without an enlarged cecum (pig) Monogastric with enlarged cecum - cecum is enlarged portion of the large intestine that permits microbial degradation of fiber after it passes through the stomach: advantage: intake not limited by forage quality. Can survive under poor forage conditions: disadvantage: problems with limited forage quantity, esp. with inefficient digestion. Monogastric animals without enlarged cecum: require diets low in fiber with high quality protein. Very little fiber digestion occurs in these animals and all essential amino acids and vitamins must be present in the diet. Variation among ruminants: concentrate selectors very selective of high quality forage items (e. g. moose, deer, goats, bulk feeders high intakes, usually of coarse, lower quality material (e. g. 3. cattle & bison). Intermediate feeders plastic (flexible) diets, capable of switching between the 2 (elk & sheep)
