Mineral composition of distillers dried grains with solubles

Production of distillers dried grains with solubles (DDGS) is expected to double within the next few years and substantially increase the quantities of DDGS available to the feed industry. To properly evaluate the potential role of this ingredient, a complete nutritional profile, including mineral composition, must be available to feed formulators. Twelve samples of commercially prepared DDGS were obtained from the northern central United States and analyzed for mineral composition. Analysis indicated an enormous range of 0.09 to 0.44% with an average value of 0.23% in sodium content. The average composition of many of the other minerals (except calcium and sulfur) agreed with projected values based on a 3-fold increase of the levels found in yellow corn grain.
