| Abstract | ||
| This study aimed to investigate the effect of inclusion of distillers dried grains with solubles (DDGS) in the laying hens’ diets on productive and reproductive performance, some egg quality traits, nutrients digestibility and some blood parameters. A total number of 90 Inshas hens and nine Inshas cocks, 28 week-old were randomly distributed into three groups and fed the experimental diets contained 0.0, 10 and 20% DDGS. The results showed that DDGS inclusion in the diet insignificant impact on rate of laying and egg mass, egg weight, feed consumption and feed conversion ratio as compared to the control group during the whole experimental period (28-48 wks of age). Egg quality traits were insignificantly affected due to feeding DDGS, whereas yolk color was significantly increased by feeding 20% DDGS diet as compared to the control. Nutrients digestibility were not affected by feeding 10% DDGS in the diet. Plasma constituents including plasma protein, indices of liver and renal function, uric acid, lipid metabolites and phosphorus were not significantly affected by feeding different levels of DDGS in the diet, but plasma calcium significantly decreased when 20% DDGS was fed and this concurred with a reduction in eggshell quality (relative weight of shell and shell-thickness). In conclusion, the present results showed that the use of DDGS can be successfully fed up to 20 % in Inshas laying hen diets without any adverse effect on laying hen performance, nutrients digestibility, egg quality and plasma constituents and economical efficiency. | ||
