The costs of feedstuffs for sheep can vary daily. Causes of these variations include season of the year, geographic location, climate and competition between man and domestic animals for common feedstuffs. Although producers may not be able to control these variables, using constant, relative feeding values of alternative feed sources can increase sheep production’s economical efficiency. Knowing how to use relative feeding values becomes especially important when one realizes that feed can account for 70% of lamb production’s total cost.
