Document Summary
Two main types of digestive systems: monogastric and ruminant. Monogastrics can eat a full range of diets from vegetation to meat. Ruminants have a very complex stomach, mostly plant diets, utilizes microorganisms in the rumen. Equine: handgun fermenters, have a large cecum where large number of microorganisms break down plant material. Digestive disturbance: loss of appetite, inability to chew and swallow, depraved appetite: may eat something that causes extreme appetite, vomiting, excess salvation, bloating: cattle particularly suffer from bloating, fever, abnormal feces. Avian: no teeth, hard cleft palate which open to nasal passage, sharp hard tongue, tears are passed into the nasal passage and then swallowed to give immune protection through oral cavity and down. Ovine: dental pad/only teeth on the bottom which is common in ruminants, chew cut to moisten it and add enzymes as well as sodium bicarbonate to balance ph in rumen.
