Distillers dried grains with solubles (DDGS) is the most common co-product generated from the ethanol industry and the production in the US of DDGS is now greater than the production of soybean meal. While DDGS is an excellent feed ingredient that in most cases can be included in diets fed to all groups of pigs at levels of at least 20 to 30%, there are also other corn co-products that may be used in diets fed to pigs.
