Dried Distiller’s Grains with Solubles are a co-product of ethanol production that is used for livestock feed in the US and around the world. Approximately 3.2 to 3.5 metric tons of DDGS production happens annually in North America.
Nutritional Value of DDGS
Distiller's dried grains with solubles (DDGS) are the dried residue remaining after the starch fraction of corn is fermented with selected yeasts and enzymes to produce ethanol and carbon dioxide. After complete fermentation, the alcohol is removed by distillation and the remaining fermentation residues are dried.
Livestock producers or international buyers looking to determine the exact nutritional value of DDGS from any given ethanol plant can visit Illinois Institute of Rural Affairs at Western Illinois University’s website. The page details moisture content, crude fat, crude fiber, and crude protein as well as multiple other amino acids and minerals and shows their percentages over time to aid in the proper diet formulation.
DDGS is primarily transported within the country via truck or rail. For international buyers, DDGS makes its way to them via containers and barges
