Feeding Corn Milling Co-Products to Dairy and Beef Cattle

Introduction The production of ethanol from corn grain has become an effective strategy to produce high quality and clean liquid transportation fuels. In fact, the growth of the U.S ethanol industry has provided an economic stimulus for U.S.-based agriculture. The feed industry plays an integral role in the ethanol production industry. For example, the primary product of the dry milling production process is ethanol; but approximately onethird of the total dry matter is recovered in the form of co-products. The supply of these co-products continues to grow at a rapid rate. As a result co-products are becoming an increasingly available feedstuff that are usually an extremely cost effective feed ingredient for dairy and feedlot cattle. Two primary types of milling processes currently exist, namely wet and dry milling and these result in quite different feed products.
