| Abstract | ||
| This study was conducted (153 hens and 24 roosters) of broiler breeder (Ross-308) at age 60 weeks. The study was carried out to investigate the effect of utilization of different levels of ZnO and addition of vitamin AD3E on concentration of Zn in the eggs components and egg fertility and hatchability percentage traits of Ross-308 broiler breeder hens at the 60 weeks of age. The experimental treatments were (T1: Control diet [without adding (ZnO) and vit. (AD3E)], T2: T1 + 2 g/kg of vit. (AD3E), T3: T1 + 25000 ppm of (ZnO), T4: T1 + 25000 ppm (ZnO) + 2 g/kg vit. (AD3E), T5: T1 + 30000 ppm (ZnO), T6: T1 + 30000 ppm (ZnO) + 2 g/kg vit. (AD3E), T7: T1 + 35000 ppm of (ZnO) and T8: T1 + 35000 ppm (ZnO) + 2 g/kg vit. (AD3E). The results obtained from this study were summarized as: The effects of interactions between treatments and age periods significantly (P<0.01) affected zinc concentration in the yolk and albumin of eggs and fertility (F) and total egg hatchability (TEH) percentage traits, but there are no significant effect on fertile egg hatchability (FEH) trait. The data were analyzed statistically by using tow-way of ANOVA with (SPSS-17 Package Program for Windows). Least Significant Difference tests (L.S.D) were used to determine the significance of difference among treatments means. Level of significance used in all results was (P<0.01) and all percentage data were converted Arcsines prior to analysis. | ||
