چکیده مقاله:
Nutritionists focused on introducing minerals as additives to poultry feed to achieve good bioavailability and increase absorption of these additives. Therefore, the current study aimed to demonstrate the effect of injecting hatching eggs with zinc methionine on the characteristics of hatched chicks and growth index. The hatching eggs injection technique was applied to inject the hatching eggs with zinc-methionine to study the traits of hatched chicks and the growth index of broilers where ۳۰۰ eggs were used from the broiler breeder, and the eggs were divided into four treatments; each treatment of ۷۵ eggs injected with zinc-methionine and at concentrations (۰, ۶۰, ۸۰, ۱۰۰ ppm) for the treatments T۱, T۲, T۳, T۴ respectively, and the studied traits were taken when the chicks hatched. The recorded data in this study showed that there was no significant effect on inactivity, general situation, case of yolk retracted inside the abdomen, abnormal checks, wing length and leg length, and significant improvement (P≤۰.۰۵) to T۴ treatment in appearance and feather condition, Eye's appearance and Leg appearance meanwhile significant improvement (P≤۰.۰۵) to T۳ treatment in naval case, residual yolk membrane, residual yolk and checks length, significant improvement of all Zn-methionine injection treatments in hatch window and total incubation period, significant improvement (P≤۰.۰۵) to T۲, T۴ treatments in growth hormone level in hatching.
