Interpretive Summary: As the fuel ethanol industry continues to expand, more coproduct materials, especially distillers dried grains with solubles (DDGS) will become available. Currently, these materials are used for animal feed, primarily beef, dairy, swine, and poultry rations. DDGS provides a nutritious feed ingredient for these animals, and provides ethanol manufacturers with additional revenue. The objectives of this presentation are to discuss several key points related to ethanol coproducts, including major types of coproducts, production methods, coproduct utilization, typical properties and compositions, as well as issues, challenges, and opptunities regarding DDGS. As the ethanol industry continues to expand, it is imperative to continue to improve coproduct quality, as well as quantity, in order to simultaneously maintain the economic viability of both the ethanol industry and the livestock industry.
