摘　　要：试验旨在探讨假蒟提取物(PSE)对育雏期儋州鸡生长性能、免疫器官指数、免疫球蛋白、血清生化指标和抗氧化功能的影响。选用500只体重相近、健康状况良好的1日龄雏鸡,随机分为5组,每组5个重复,每个重复20只雏鸡。BC组(对照组)雏鸡饲喂基础日粮,PC组(抗生素组)在基础日粮中添加200 mg/kg恩诺沙星,PSE1组、PSE2组、PSE3组分别在基础日粮中添加100、200、300 mg/kg的PSE。试验期28 d。结果显示,PSE1组雏鸡血清过氧化氢酶活性显著提高(P<0.05);PSE1组和PSE2组雏鸡血清总抗氧化能力显著提高(P<0.05);PSE2组和PSE3组雏鸡血清尿酸含量、丙二醛含量显著降低(P<0.05)。研究表明,添加PSE可提高雏鸡生长性能和抗氧化功能,降低血清中尿酸含量,且添加剂量以200 mg/kg为宜。The experiment was to study the effect of Piper sarmentosum extract(PSE)on growth performance,immune organ index,immune globulin,serum biochemical indices and antioxidant function of chicks.A total of 500 one-day-old Danzhou chicks with similar body weight and good health were divided into five groups,with five replicates in each group and 20 chicks in each replicate.The chicks in BC group(control group)were fed with basal diet,the chicks in PC group(antibiotic group)were fed with basal diet supplemented with 200 mg/kg enrofloxacin,and the chicks in PSE1 group,PSE2 group and PSE3 group were fed with basal diet supplemented with 100,200 and 300 mg/kg PSE,respectively.The feeding period was 28 d.The results showed that the catalase activity in PSE1 group was significantly increased(P<0.05).The total antioxidant capacity in PSE1 group and PSE2 group was significantly increased(P<0.05).The serum uric acid content and malondialdehyde content were significantly decreased in PSE2 group and PSE3 group(P<0.05).The experiment indcates that PSE supplementation can improve the growth performance and antioxidant performance of chicks,and reduce the content of uric acid in serum,the appropriate dosage of PSE is 200 mg/kg.
