The use of high quality corn DDGS in layer diets is an excellent partial replacement for corn, soybean meal and inorganic phosphate and supports excellent layer performance and egg quality. DDGS could be added to the diet of laying hens at levels of 10 to 20%, accounting for about 30% of the total dietary protein, without synthetic lysine supplementation, and has no effect on egg production or egg weight. Also an improvement in interior egg quality (Haugh units) was seen. Because of high xanthophylls in DDGS, egg yolk colour is improved. The oleic acid content decreased, and linoleic acid increased in egg yolk as increasing levels of DDGS were added to the diet, but the amount of saturated fatty acids in the yolk was not affected by DDGS supplementation. So feeding layer diets containing up to 15% DDGS did not affect production.
