More and more ethanol co-products are available for livestock feed because of the rapid growth of the ethanol industry in South Dakota. The three main co-products are Distillers Grains, Solubles, and Distillers Grains with Solubles, and they can be either “wet” or “dried” depending on the manufacturing process. Since, in the U.S., on-farm feed mixing and swine feeding systems are almost exclusively designed for dry feed, we deal here only with the dried products. All ethanol plants in South Dakota mainly produce Distillers Dried Grains with Solubles (DDGS), limiting our discussion further to only DDGS as a feed ingredient for swine.
