Document Summary
Knowledge of the different types of digestive systems is critical in selecting the proper feeds for animals. Understanding the chemical and physical changes that occur during the digestion process leads to more efficient animal feeding. Overview: dietary preference classification, anatomical git classification of herbivores, ruminant classification, summary of dairy cow git. Carnivores: consumes solely animal sources, higher quality food, capacity of the stomach is large, higher intake of essential nutrients, minimal microbial fermentation simplest git large volume meals. Omnivores: plant and animal sources, most adaptable animal, many git variations, eat meat and vegetation like roots, berries, seeds, and young shoots, may practice coprophagy (eating feces) fiber can be used. Use the nutrients excreted in feces if the animal is deficient in protein. Herbivores - ruminants and nonruminants: graze and browse vegetation, nutrient extraction depends on git, non-ruminants less efficient fiber digesters ruminants rumination, high fiber utilization. Sheep: pregastric fermentation = extensive, hindgut = medium similar to cattle and goats.
