All animals supply their nutritional needs by eating feed in such a way that the internal body expenditure of nutrients for energy purposes, growth, and other body uses (such as milk production) is balanced by the quantity and quality of feed eaten. This balance is determined by several physiological control systems that determine when and how much feed will be eaten. This results in a stable body weight or in the young, a steady uniform growth. However, the feeding behavior and digestive mechanisms of the common domestic animals vary widely, from the relatively simple food of a typical carnivore (such as the cat) to the bulky, tough, and difficult-to-digest feed of the herbivorous cow or horse. This wide variety of eating habits and diet and the accompanying modifications of the digestive system calls for a corresponding variety of physiological mechanisms to bring about the desirable matching of body needs and eating behavior.
