This experiment was conducted to study the effect of adding (6.6 , 160 , 5) mg/kg from vitamins (A, E, K) respectively to the rations of broilers which were vaccinated by Eimeria tenella vaccine locally produced and the effect of this addition on the improvement of some physiological and productive characteristics of broilers. 360 faw bro unsexed day old chicks were used. They were divided into nine treatments with two replicates. The results revealed that the addition of vitamins A and E combined in the rations gave a significant (P<0.05) improvement on some physiological and productive characteristics of broilers compared with only vaccinated . Vitamin K, however, had no significant effect on physiological and productive characteristics except in packed cell volume.

Efficacy of vaccination against coccidiosis by using local produced Eimeria tenella vaccine was tested. This had been done by testing vaccine roles in protection of broilers against the infection with Eimeria tenella. Four different routs of vaccinations namely (crop inoculation, drinking water, feed, and spray) were applied. Three attenuated gamma-radiation dozes for oocysts were tested (200 – 250 – 300) and two diffrernt oocysts number (1000 – 2000) as vaccine doze were implemented in this experiment on 10 days old chicks. The results revealed that vaccination with any routs with any numder of oocysts attenuated with any dozes of gamma-radiation gave significant (P< 0.05) differences in immune response and birds performance when compared with two control treatments which were not vaccinated. Birds vaccinated through crop inoculation or drinking water of 2000 oocysts which attenuated by 200
