THE EFFECT OF IN-OVO INJECTION OF BEE VENOM ON HATCHABILITY AND SOME IMMUNOLOGICAL PARAMETERS OF ALEXANDRIA CHICKS’ STRAIN AT HATCH

Researchers are trying to boost the immune system of poultry birds through use natural immune-stimulants including bee venom. There is a scarcity in literature about venom for ovo injection studies. The aim this study investigate effect two levels freeze-dried (BV) (10 and 20 µg/egg) into eggs Alexandria breeder hens at 18-day incubation on hatchability percentage, hatching weight per egg weight, response young chickens. doses BV used current work were based pilot trial obtained directly before main experiment work. A total number 900 fertile day 18 study. Eggs weighed randomly allocated three experimental groups as: control (C), low dose high with 300 each. Results showed that in-ovo 10 µg/egg significantly increased percentage (89.45%) over (87.5%) (77.73%). highest relative chick was observed group followed by lower higher groups. increase has reduction weight. protein albumin values decrease (P?0.001) µg BV/egg compared group. triiodothyronine (T3), thyroxine (T4) concentrations chick's blood hatch both T3 T4 serum hatch. In addition, results spleenrelative Also, same trend bursa conclusion, resulted better eggs.
