摘　　要：为了研究刺五加提取物(ASE)替代抗生素降低仔猪早期断奶应激的效果及其作用机制。刺五加提取物多糖、黄酮和有机酸含量分别为2.94,0.19和1.04%;试验选用96头体重相近的21日龄杜×长×大断奶仔猪,按体重和性别随机分为3个处理,每个处理4个重复,分别饲喂基础日粮、添加ASE日粮(1g/kg)和添加抗生素日粮(0.04%杆菌肽锌+0.03%咔吧氧)。试验期为14d,观察仔猪生长性能,测定7和14d血清抗氧化指标等的变化。与基础日粮组相比,ASE和抗生素分别提高了仔猪日增重(ADG)16.81(P>0.05)和24.66%(P<0.05),均显著降低了料肉比(F/G)(P<0.05);与抗生素组差异不显著。ASE和抗生素均可提高血清SOD水平;但是,在抗生素组中,第14d仔猪血清SOD有降低的趋势(从147.96±15.88U/mL降低至125.68±14.26U/mL)。ASE有提高断奶后第7和14d血清GSH含量的趋势(P=0.235和0.211),并极显著降低了7和14d血清MDA水平(P<0.05)。结果表明,ASE可促进仔猪生长,提高机体抗氧化能力,在一定程度上可以替代抗生素。This study was conducted to investigate the effect of Acanthopanax senticosus extract (ASE) on the growth performance and antioxidant capacity of weaned piglets.Dried AS herb was decocted in boiling distilled water (200 g/L) for 2 h.The decoction products were filtered and lypholized.The yield of extract was about 25% (w/w),with total polysaccharides,flavone and organic acids 2.94,0.19 and 1.04%,respectively.Ninety-six Duroc×Landrace×Yorkshire piglets weaned at 21 days of age (BW=5.64±0.48 kg) were randomly...
