铁和维生素A及其互作效应对产蛋鸡生产性能和血清抗氧化指标的影响
Effects of Iron,Vitamin A and Their Interaction on Production Performance and Serum Antioxidant Indices in Laying Hens
摘要
Abstract
The purpose of this paper was to investigate the effects of iron and vitamin A on performance and serum antioxidant indices in laying hens.A 3×2 completely random experiment was designed.A total of four hundred and thirty-two Hyline Brown laying hens were randomly divided into 6 treatments.Iron supplementation levels were 0,30 and 60 mg/kg,and vitamin A supplementation levels were 4000 and 8000 IU/kg.It is found that the supplementation of dietary iron significantly increased average egg weight,the activities of Cu/Zn-superoxide dismulase,glutathione peroxidase and ceruloplasmin in serum,and the concentration of hydrogen peroxide and hydroxyl radical inhibition in serum(P0.05),and significantly increased total antioxidant capacity in serum at 31-34 weeks(P0.05).The supplementation of dietary vitamin A significantly increased the activity of ceruloplasmin in serum(P0.05).Interaction between iron and vitamin A significantly affected the activities of glutathione peroxidase and ceruloplasmin in serum(P0.05).It is concluded that the supplementation of iron in diet did not improve the production performance of laying hens,but promoted the production of free radicals,and increased the activity of antioxidase.关键词
