Dried distillers grains with solubles (DDGS) have long been an undervalued coproduct. But at 28 to 32 percent protein, it contains too much protein to realize its full value as ruminant feed. This is a common challenge across the animal feed industry and represents a huge opportunity in the field of precision animal nutrition. Ultimately, it looks likely that the long-term trend of maximizing the value of ethanol coproducts, including distillers grains, will continue. Processing technologies will continue to be critical to maximizing the technical performance of protein coproducts. Also, shaping their value-creation potential for the ethanol industry.
