Effect of In-Ovo inoculation with royal jelly on weight gain of chicken embryo

Three groups of fertilized chicken eggs (10 eggs per group) were injected at 12 days of incubation; the first group were injected with diluted royal jelly (with a phosphate buffer solution at 1:1) in amount of 0,05ml in to theallantoic fluid. Second group were injected into the yolk sac with 0.05 ml of diluted royal jelly, while third group left as a control group which were divided into two groups: control 1 were injected with phosphate buffer solution in allantois and control 2 were injected with phosphate buffer solution in the yolk sac. Eggs were weighed before and after injection. We concluded that injection via allantoic have significant (P 0.05) effect on hatched chick as compared to other group
