The effect of adding vitamins A, E, and K in broilers rations vaccinated by Eimeria tenella vaccine locally produced on some physiological and productive characteristics of broilers.

Abstract

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.
