  • Corn distillers dried grains with solubles (DDGS) and wheat millrun are co-products from the ethanol and dry milling industries characterized by high non-starch polysaccharides (NSP) content that limit nutrient digestibility of co-products, which could be improved by supplementation of NSP-degrading enzymes. Nutrient digestibility of diets containing co-products with supplemented NSP-degrading enzymes was evaluated in 3 experiments. Supplemental NSP-degrading enzymes did not increase the nutrient digestibility of corn DDGS- and wheat millrun-based diets (P > 0.10) however, feed enzymes increased (P < 0.01) the apparent ileal digestibility (AID), apparent total tract digestibility (ATTD) of energy, AID and ATTD of NSP and standardized ileal digestibility (SID) of crude protein in a wheat grain diet including 40% wheat millrun. Furthermore, these enzymes increased (P < 0.05) the SID of Arg, His, Trp, Cys, Glu, Gly and Ser. In conclusion, supplementing NSP-degrading enzymes increased the limited energy, protein, and AA digestibility in wheat millrun.
