- Abstract
The aim of study was to determine the effects of spraying hatching eggs with ascorbic acid and in ovo injection with nutrientsoneggs shell and hatchingparameters. In total, 432 fertilized hatching eggs (Ross308) with average weight 62.0±1 g., were randomly distributed into eight treatments of 54 eggs per treatment with three replicates of 18 eggs each. The experimental treatments were involved: T1: Control (eggs, without spraying or injection), T2: (Eggs, sprayed with ascorbic acid), T3: (Eggs, sprayed ascorbic acid and injected with 0.2 ml./egg of pollen extract solution), T4: (Eggs, sprayed with ascorbic acid and injected with 0.2 ml./egg of diluted honey solution), T5: (Eggs, sprayed with ascorbic acid and injected with 0.2 ml./egg of citric acid), T6: (Eggs, injected with 0.2 ml./egg of pollen extract solution), T7: (Eggs, injected with 0.2 ml./egg of pollen extract solution) and T8: (injected with 0.2 ml./egg ofcitric acid). On 16 day of incubation eggs sprayed with 30gm. of ascorbic acid/ 1Liter (50 ml./1000 eggs). On day 18 of incubation eggs were injected with nutrients into Chorioallantoismembrane. Results showed a significant decrease (P<0.05) in shell thickness and strength of eggs shell fracture for all ascorbic acid sprays treatments compared with control. Also, results indicated significant decrease (P<0.05) for T3 in hatching time as compared with other treatments. No significant differences between treatments in hatchability, delayed embryonic mortality, dead after piping, live after piping, to naparameters and leg’s length(cm.), while T3 showed significant increase (P<0.05) in weights of hatched chicks. Moreover, results showed a significant decrease (P<0.05) in weight of yolk sac for T2, T3 and T8 compared with T4, T5 and T7, while no significant differences recorded between treatments T1, T2, T3, T6 and T8. No significant differences showed between treatments in relative weights of Heart, Liver, Intestine and Fabricious on1st day of age.
