Abstract :

The aim of the present research was to, evaluate the effect of dietary supplementation with different levels of zinc (0, 50, 75, 100 mg/kg diet) on egg quality traits of Cobb 500 broiler breeder hens. The four experimental diets were as follows: T1 = the basal diet (control) without any addition (0 Zn). T2 = 50 mg Zn (pure zinc)/kg diet. T3 = 75 mg Zn (pure zinc)/kg diet T4 = 100 mg Zn(pure zinc)/kg diet. From the applied results which were selected a long the entire research period, we could be conclude the following: All of the egg quality traits and total mean of egg quality of broiler breeders hens were significantly affected by the different levels of dietary zinc supplementation except in both ESG and shell thickness. On the other hand, supplemental dietary zinc detected the highest (p<0.05) egg weight/week as compared to control group and had a significant effect (p<0.05) in accumulative egg weight.
