Food Requirements for Different Animals
Have you ever wondered why ruminant livestock such as cattle, sheep and goats, or wildlife such as deer, elk and bison eat what they do? For example, cattle and bison eat primarily grass; deer eat primarily forbs and browse (the edible leaves and stems of woody plants), but very little grass. Some ruminants, such as goats, have the ability to choose their diet across a wide spectrum of available plant types: grasses, forbs and woody vegetation.
