Livestock and Co-Products
A modern dry mill ethanol refinery produces approximately 2.8 gallons of ethanol and more than 17 pounds of distillers grains from one bushel of corn. In 2008, ethanol biorefineries produced approximately 23 million metric tons of distillers grains. While ethanol production utilizes the grain's starch; the protein, minerals, fat and fiber concentrated during the production process produce a highly valued and nutritious livestock feed. For dry mill ethanol refineries, which make up the majority of production, most feed is dried and sold as Distillers Dried Grains with Solubles (DDGS). Approximately 20-25% of the feed is shipped wet locally, reducing energy input and transportation costs while providing another market for producers.
