Distiller’s dried grains with solubles (DDGS) are a common feedstuff in poultry diets, however, digestibility estimates vary with production method and strain (broiler vs layer). The objective of this study was to determine the amino acid digestibility of 34.1% (as fed) high-protein DDGS in straight-run Cobb 500 broiler chickens. Calculated standardized ileal amino acid digestibility (SIAAD) of indispensable amino acids (AA) ranged from 81.20 to 90.41%. The SIAAD of dispensable AA ranged from 16.16 to 89.78%. The digestibility of limiting AA in HiP DDGS was greater than reported digestibility values of the same AA in DDGS. Additional research is needed to further illustrate the effect of DDGS production on the value of feeding high protein (HiP) DDGS in broiler chickens.

Changes to the production method of distiller’s dried grains with solubles (DDGS), a common feedstuff in poultry diets, can alter the nutrient profile and energy content. Estimates of DDGS digestibility vary as a result of the altered production method, removal of value-added products like distiller’s corn oil, as well as the strain of chicken used (broiler vs. layer). The objective of this study was to determine the energy digestibility of high protein DDGS (HiP DDGS) fed to straight-run Cobb 500 broiler chickens. The apparent nitrogen-corrected metabolizable energy of HiP DDGS was calculated at 2,710 kcal/kg. Additional research is needed to further illustrate the influence of production method on HiP DDGS feeding value in broiler chickens.

Dried distiller’s grains with solubles (DDGS) are commonly fed at an inclusion of 10% or less in broiler diets with the added benefit of an improved ability to utilize the available nutrients compared to layers fed the same inclusion. Combined with intentional changes to processing to enhance the nutritional quality of DDGS, there is the potential to increase the utilization of DDGS when fed to broilers. The objective of this study was to determine the effects of feeding up to a 20% inclusion of high protein DDGS (HiP DDGS) on broiler performance in straight-run Cobb 500 broiler chickens. Birds fed diets containing 15 and 20% HiP DDGS gained less weight than control (p < 0.05) but did not have a different feed intake (FI). Birds fed the 20% HiP DDGS diet had a less efficient FCR than the control. Additional research is needed to further illustrate the value of feeding HiP DDGS in broiler chickens.
