RESUMEN
Objective: To investigate the in ovo injection (IOI) of vitamin E (VE) on serum post-hatch immunological parameters and broiler chicken performance. Methods: Fertile eggs (n=400) were distributed into four groups of 100 eggs. On 14th day of incubation, two groups were injected with 0.5 mL of 15 or 30 mg VE dissolved in physiology serum. Rest two groups were used as sham control (injected with 0.5 mL physiology serum) and un-injected control. The hatched chickens from each group were randomly assigned to four replications of 12 chickens and reared under standard condition. Results:Hatchability percentage was apparently increased (P Conclusions:Broiler chicken performance did not affect with IOI of VE, while hatchability and post-hatch immunity status were boost up by IOI of 30 mg/egg VE.
