Document Summary

Mammals cant break the beta bond in cellulose! Other enzymes from mucosal lining of the duodenum. Dietary carbohydrate levels exceed the animal"s ability to digest it, diarrhea may occur. Monosaccharides are rapidly absorbed by the small intestine. Transported via blood to metabolized as energy source - fuel. No enzymes to digest cellulose, hemicellulose and other carbs in fibrous feedstuffs. Occurs in rumen, cecum and colon from microbial action with varying success action with varying success. Horse > swine and rabbits > poultry, dogs and cats. Eat solid food, bacterial and protozoal populations gradually develop in the rumen. Enabling the animal to digest more complex carbohydrates. Microorganisms digest the starches, sugars, cellulose, and other polysaccharides. Vfas absorbed through rumen wall - source of energy. Amylase secreted into the small intestine is low. Less able to digest starch in the small intestine. Monogastrics digest with enzymes and do not have the enzymes for many complex carbs.
