摘　　要：为了研究日粮中添加不同水平维生素C对肉鸡抗氧化和免疫性能的影响，选用1日龄爱拔益加（AA）肉仔鸡960只，随机分为3个处理，每个处理4个重复，每个重复80只。试验日粮参照AA肉仔鸡推荐标准配制，3个处理的口粮维生素C水平分别为：0mg／kg、100mg／kg、150mg／kg。试验期49d。研究结果表明：日粮中添加100～200mg／kg稳定性维生素C可以改善肉鸡增重，降低死淘率（P〈0．05）。不影响肉鸡脾脏指数、法氏囊指数和胸腺指数（P〉0．05）。肉鸡日粮中添加稳定性维生素C100mg／kg和200mg／kg，可以使血清中Cu—ZnSOD活性提高11．14％和23．99％；血清中谷胱甘肽过氧化物酶的活性分别提高0．48％和4．95％。添加200mg／kg维生素C，可以使血清中MDA含量降低了11．71％。由此可以说明，肉鸡日粮中添加稳定性维生素C可以提高肉鸡抗氧化能力，改善生产水平，不影响免疫功能。960 AA broilers were divided into three treatments, four replications for each treatment, to study the effects of different supplemental levels of Vitamin C on antioxidantion and immune function. Vitamin C levels in the three treatments of diets were 0 mg/kg, 100 mg/kg and 200 mg/kg respectively during the 49 days experiment. Other nutrition levels were all reach to AA broiler. The results showed that daily gain, Cu - Zn SOD, GSH -px activity could be improved with increasement of Vitamin C levels, thymus, spleen and burse index were not affected, but MDA level was decreased. When Vitamin C was increased to 100 mg/kg and 200 mg/kg, Cu - Zn SOD were improved by 11.14% and 23.99% , and GSH - px were improved by 0.48% and 4.95%. MDA level was degraded by 11.71% when Vitamin C was increased to 200 mg/kg. The supplementation of Vitamin C could improve antioxidantion and could be increased gradually with Vitamin C levels, but high level of Vitamin C did not increase the immune function.
