Beef cattle production is a strong animal industry within the United States and throughout the world. Since beef cattle can graze forages in the open range and pasturelands, they serve a unique role in providing high quality protein for human consumption from byproducts and forage sources that humans and non-ruminant animals do not consume. Considerable land in the U.S. and the world that will not support intensive crop production, can often times sustain grasses and forages that provide conservation of the land, and produce feeds that cattle can utilize.
