| Abstract: |
A total number of 500 fertile eggs were used in this study collected from Arbor Acres and Ross parental flocks to investigate the effect of injecting incubated eggs with Ascorbic acid (vitamin C) on the productive performance of the hatched chicks. Eggs of each strain were randomly equally divided into five groups (each of 100 eggs). Eggs of the 1sr, 2nd and 3rd groups were injected with 3, 6 and 9 mg of, respectively. The 4th group was used as a shim (eggs drilled only), while the 5th group was considered as control. Results obtained could be summarized as follows; Ross strain significantly decreased embryonic mortality and correspondingly increased hatchability percentage. Treatments applied had highly significant effect on embryonic mortality and hatchability. Ross strain significant increased body weight, weight gain and growth rate during the all periods of estimation when compared with those of Arbor Acres strain. The highest averages of body weight and weight gain were observed in chicks hatched from eggs injected with 6 and 9mg ascorbic acid (vitamin C) when compared with other treatments applied and control group. Birds of Arbor Acres showed the better feed conversion values at all periods of estimation compared with Ross strain. The best feed conversion values at the period from (0-6) weeks of age were found in chicks hatched from eggs injected with 3 or 9mg ascorbic acid (2.11 and 2.11g feed/g gain, respectively). Chicks hatched from eggs of Ross strain showed the highest economic efficiency at (0-6) week (143.53%) when compared with Arbor Acres strain (142.65%), respectively. Chicks hatched from eggs injected with ascorbic acid at a level of 3or 6mg showed the highest economic efficiency values at (0- 6) week (170.35 and 155, 94%, respectively) when compared with different treatments applied. It could be concluded that, Ross strain and injection incubated eggs with 3 and 6 mg ascorbic acid seemed to be adequate to a chive the favorable results and is being recommended from the economic point of view. |
