DDGs (distillers dried grain with solubles) are co-products of ethanol production. They’ve been used as loose feed for swine, poultry and dairy cows as well as beef cattle. Now POET, the world’s largest producer of biofuels, has developed a pellet form that is rich in nutrients and less likely to blow away, crumble, or be stamped into the ground by animals. This is an innovative way to feed livestock and use ethanol co-products.
Your students can create their own DDGs and test nutrient values in corn with these Energy and ethanol lessons.
