摘　　要：旨在研究发酵中药微生态制剂对断奶仔猪生长性能、血清生化指标和抗氧化能力的影响。选用23日龄断奶的杜×长×大三元杂交健康仔猪120头,随机分为4组:对照组饲喂基础日粮、抗生素组(基础日粮+0.075 g/kg金霉素+0.015 g/kg恩拉霉素+0.1 g/kg喹乙醇)、试验Ⅰ组(基础日粮+0.3%发酵中药+0.15 g/kg枯草芽孢杆菌TL)、试验Ⅱ组(基础日粮+0.3%发酵中药+0.3 g/kg枯草芽孢杆菌TL),每组3个重复,每个重复10头,试验期30 d。结果表明,试验Ⅰ组的平均日增重高于对照组(P<0.01),料肉比较对照组降低(P<0.05),与抗生素组相比,差异均不显著。试验Ⅰ组、Ⅱ组的腹泻率低于对照组和抗生素组(P<0.01)。与对照组和抗生素组相比,试验Ⅰ组、Ⅱ组的血清总蛋白、葡萄糖浓度上升(P<0.05),甘油三酯浓度下降(P<0.05)。在血清抗氧化指标方面,试验Ⅰ组和Ⅱ组的血清T-SOD、GSH-Px活性显著高于抗生素组,MDA含量显著降低。由此可见,发酵中药微生态制剂具有与抗生素相当的促生长能力,能够降低断奶仔猪腹泻率、增强免疫功能、提高机体抗氧化能力。Aiming to study the effects of fermented traditional Chinese medicine microecological preparations on the growth performance,blood biochemical indexes and antioxidant capacity of weaned piglets.120 piglets(Duroc×Landrace×Yorkshire)weaned at 23 days of age were divided into four groups randomly,with three replicates in each group and ten piglets in each replicate,i.e.control group(basic diet),antibiotic group(basicdiet+0.075 g/kg chlortetracycline,0.015 g/kg enramycin and 0.1 g/kg olaquindox),test groupⅠ(basicdiet+0.3%fermented Chinese medicine and 0.15 g/kg Bacillus subtilis TL)and test groupⅡ(basicdiet+0.3%fermented Chinese medicine and 0.3 g/kg Bacillus subtilis TL),30 days trial period.The results showed that the average daily gain of test groupⅠwas significantly higher than that of control group(P<0.01),the feed to gain ratio(F/G)of test groupⅠwas significantly different from that of control group(P<0.05),The diarrhea rate of test groupⅠandⅡwas significantly lower than that of antibiotic group(P<0.01).Compared with control group and antibiotic group,the serum ALB and GLU in the test groupⅠandⅡwere significantly higher(P<0.05),the content of serum TG in test groupⅠandⅡwere significantly lower(P<0.05).Compared with antibiotic group,the levels of GSH-Px and SOD in blood of test groupⅠandⅡwas significantly higher,and MDA content significantly lower.It can be seen that microecological preparation of Chinese medicine agents could improve growth performance,reduce diarrhea rate,enhance immune function and improve antioxidant capacity.
