Distiller Dried Grains

Ethanol plants blend and dry these two residues to produce distiller dried grains. The distiller dried fraction has the highest concentration of nutrients compared with DDG. It is a rich source of vitamins, and is the lowest in fiber and highest in fat, yielding a DE value that is approximately 91% of that found in corn. Since DDGS is a blend of DDS and DDG, the nutrient composition of DDGS is between DDS and DDG. This is generally the case with the following exceptions: crude protein, arginine, histidine, lysine, methionine, cystine, tryptophan, magnesium, sodium, sulfur, selenium, vitamin B12, and folacin.

Ethanol plants use milo, wheat, or barley in the fermentation process, depending on geographical location and time of the year. As a result, nutrient composition can vary among DDGS sources. Because of the near complete fermentation of starch, the remaining amino acids, fat, minerals and vitamins increase approximately three-fold in concentration compared to levels found in corn. Despite the significant increase in crude protein, the poor amino acid balance of DDGS must be addressed when formulating swine and poultry diets.
