摘　　要：本试验选用1日龄固始鸡4C雏鸡540只,随机分成9组,每组60只.试验预试期为1周,试验期为6周.饲养49 d后,通过测定固始鸡4C商品代肉鸡血液中谷胱甘肽过氧化物酶(GSH-Px),超氧化物歧化酶(SOD)以及组织中丙二醛(MDA)含量,比较不同的VE与VC添加水平对固始鸡4C商品代肉鸡血液指标和脂质抗氧化的影响.结果表明:在饲粮中添加不同浓度的维生素E与维生素C可以显著降低贮存14 d腿肌中丙二醛含量,同时可以显著提高血液中超氧化物歧化酶与谷胱甘肽过氧化物酶的活性(P<0.05).本试验结果提示:在固始鸡4C饲粮中添加高浓度的VE和VC在一定程度上具有清除自由基、减少脂质过氧化的协同作用.A total of 540 one-day-old Gushi 4C broilers were randomly allocated to nine treatments with 60 broilers for each treatment. The prefeeding phase of the experiment was one week, the trial feeding phase was six weeks. After raised for 49 days,this experiment was conducted to evaluate the influence of different dietary vitamin E and C levels on the lipid antioxidation in the tissues and the serum parameters by investigating the malonyldialdehyed concentration, the serum GSH-Px and SOD activity. The results show that the malonyldialdehyed concentration of the thigh muscle stored for 14 days in treated groups is lower than the control（P〈0. 05）, and the activity of the serum SOD and GSH-Px concentrations are improved significantly（P〈0.05）. The results of this experiment imply that the higher vitamin E and C as dietary supplementation have the interaction for eliminating free radicals and minimizing the lipid superoxidation to some extent.
