Abstract: Ninety-six 56-day-old Chinese native chickens were selected and randomly divided into 16 dietary treatments of 60 chickens each to determine the effects of dietary vitamin A and E supplemented on the performance of chickens. Diet were formulated to contain four graded levels of supplemental Vitamin A (0,5 000,10 000,20 000 IU/kg) and four graded levels of supplemental Vitamin E (0,30,60,120 IU/kg)by a 4×4 factorial design. The results showed that: Within the supplement range of 0~10 000 IU/kg for vitamin A and 0~60 IU/kg for vitamin E, ADG and F/G increased gradually .Plasma vitamin E tended to decrease when dietary vitamin A supplementation exceeded 10 000 IU/kg.Supplementation of high levels of vitamin A could increase plasma TBARS significantly, and high levels of Vatamin E could improve the oxidative stability of lipid. Deposition of pigment was inhibitated when supplementation of vitamin A was over 20 000 IU/kg.With increase of vitamin E supplementation ,the skin color was enhanced.Dietary vitamin A and E and the interaction had significant affected on serum antibody titer of Newcastle disease.In conclusion, the optimum level of dietary supplemental vitamin A, E for Chinese native chickens was respectively 5 000~10 000 IU/kg, 30~60 IU/kg.
