Technical Abstract: Rapid growth of the ethanol industry in the United States has generated large quantities of ethanol coproducts, primarily distillers dried grains with solubles (DDGS), available as a feedstuff for livestock. These coproducts are often added to livestock diets as a source of protein and energy. The protein supplied tends to be a good source of rumen-undegraded protein, whereas energy is provided by the highly fermentable fiber and fat. In addition, DDGS is a source of minerals. This needs to be considered when formulating diets for livestock to prevent excessive dietary mineral concentrations. As the ethanol industry continues to develop, new or altered byproducts will appear on the marketplace for use in livestock diets. Nutritionally defining these products will be necessary to determine how they can be used in livestock diets.
