【摘要】 本文旨在研究沙棘黄酮对 AA 肉鸡生产性能和免疫功能的影响。选择1日龄健康从肉仔鸡360羽,采用单因子试验设计,随机分为3个处理组,每组4个重复,每个重复30只,分别为基础日粮组、0．1％沙棘黄酮组、 0．2％沙棘黄酮组,进行为期8周的饲养试验。分别于第3、6、8周采集样品,分析测定日增重、料重比、营养物质表观消化率、免疫器官指数、血清免疫球蛋白、血清新城疫抗体效价、T 淋巴细胞比率。结果表明：在肉鸡生长全期饲料中添加0．1％、0．2％沙棘黄酮对 AA 肉仔鸡的生长性能、免疫器官指数、血清 IgA 含量没有显著影响(P＞0．05), 对饲料中蛋白质表观消化率有提高趋势(P=0．054),显著提高了饲料中钙的表观消化率、56日龄血清 IgG 含量、21 日龄血清 IgM 含量、21、42和56日龄血清新城疫抗体效价、21和56日龄 T 淋巴细胞比率(P＜0．05)。肉鸡饲料中添加沙棘黄酮可提高从肉鸡的免疫功能和对饲料中钙的利用率。更多还原

【Abstract】 A total of 360 1-day-old health male Arbor Acre (AA) broilers were randomly used for 3 dietary treatment.Each treatment was replicated four times with thirty broilers each.The dietary treatments were basal diet,basal diet+0.1% fla- vonoids of sea bucktborn and basal diet+0.2% flavonoids of sea buckthorn.Daily gain,ADFI,nutrient digestibility,rela- tive weight of immune organs,serum IgG,IgA,IgM,serum antibody titres and T lymphocytes percentage were determined. The results showed that the growth performance,relative weight of immune organs,and serum IgA of AA broilers were not significantly affected by treatments (P＞0.05),and apparent digestibility of protein in diet inclined to increase (P= 0.054),but apparent digestibility of calcium in diet,serum IgG at 56th day,serum IgM at 21st day,serum antibody titres at 21st,42nd,56th day and T lymphocytes percentage at 21st,56th day were significantly increased (P＜0.05).Immune function and apparent digestibility of calcium in diet of AA broilers significantly increased by different addition level of fla- vonoids of sea buckthorn.更多还原
