DDGS is an excellent feed ingredient for use in broiler diets and contains approximately 85% of the energy value in corn/Rice, has moderate levels of protein and essential amino acids, and is high in available phosphorus. Layer and broiler diets can easily contain up to 10% DDGS with little, formulation adjustments for energy and amino acids. benefits of feeding DDGS to poultry and concluded that DDGS is an acceptable ingredient for use in poultry diets and can be safely added at levels of 5-8% in starter diets for broilers and 12-15% in grower-finisher diets for broilers ,and laying hens. Phosphorus availability is relatively high in DDGS when fed to poultry. Results showed that phosphorus bioavailability in DDGS was 67% and supplemental phytase and citric acid could release from 0.04 to 0.07% phosphorus from DDGS and increased the bioavailability of phosphorus in DDGS from 62 to 72%.

The use of high quality DDGS in layer diets confirming that it is an excellent partial replacement for corn/Rice. There was no difference in Haugh units between dietary treatments from 25 to 31 weeks of age. At 43 weeks of age, layers fed the low energy, 15% DDGS diet had lower Haugh units compared to hens fed the high energy, 15% DDGS diet. Furthermore, feeding the 15% DDGS diets had no appreciable effect on egg yolk color. Based upon these results, the researchers concluded that DDGS is a very acceptable feed ingredient in layer diets and the maximal dietary inclusion level of DDGS should be 10 to 12% in high energy commercial diets, but lower dietary inclusion rates may be necessary in lower energy diets. It is consistently observed positive performance and meat quality results when DDGS is added to broiler diets. DDGS can be added to broiler diets at levels up to 25% to achieve good performance if dietary energy level is held constant. diets containing 0, 5, 10 or 15% DDGS from 12 to 35 days of age and showed no significant effects of increased DDGS levels on feed intake, weight gain, excreta quality or digestibility of protein and organic matter . Digestibility of DDGS protein was estimated to be 77%. Results from this study suggest that DDGS can be used as an effective protein source in finishing broiler diets at levels up to 10-15%. adding up to 15% DDGS in broiler diets had no effect on growth performance, color scores and firmness of breast and thigh muscles. DDGS can be added up to 15% of the diet to decrease the feed cost by partially replacing some of the corn and soybean meal, without any negative effect on growth performance and meat quality. Current recommended maximum dietary inclusion levels for corn/Rice DDGS are 15% for broilers, higher levels of corn DDGS can be used successfully with appropriate diet formulation adjustments for energy and amino acids, formulating diets containing corn DDGS, digestible amino acid values should be used especially for lysine, methionine, cystine, and threonine.
