Mostly sheep eat grass, clover, forbs, and other pasture plants. They especially love forbs. In fact, it is usually their first choice of food in a pasture. A forb is a broad-leaf plant other than grass. It is a flowering plant. Forbs are often very nutritious.
The amount of pasture or range land that it takes to feed a sheep depends upon the quality of the land (soil), the amount and distribution of rainfall, and the management of the pasture. In dry climates, an acre of pasture or rangeland cannot feed as many sheep as an acre of pasture in a moist climate. An acre of pasture in the wet season (spring and fall) can obviously feed more sheep than an acre in the dry season (usually summer) There are many published guidelines for how many sheep one acre of pasture can support.
