| Abstract | ||
| This study was conducted at the poultry farm, College of Agriculture, Babylon University. The experiment Aimed to investigate the effect of early feeding either injection hatching eggs by different levels of ascorbic acids on 17.5 days of embryonic incubation or offering diet to hatched chicks inside Hatcher. Experimental treatment groups were: T1; negative control ( without injection) , T2; positive control ( in ovo injection with sterile distilled water on 17.5 days of incubation), early feeding hatched chicks inside Hatcher , T4, T5 and T6 mean in ovo injection with solution containing 0.2, 0.6 and 1 % of ascorbic acid on 17.5 days of incubation respectively. Results indicated an increase in hatchability, chick’s weight at hatch, weekly live body weight, weight gain and an improvement in feed conversion ratio in treatment groups received ascorbic acids. As well as T5 (0.6%) surpassed other treatment groups in all studied traits. | ||
