摘　　要：为研究日粮中同时添加太子参茎叶多糖与枯草芽孢杆菌对断奶仔猪生长性能、血清免疫指标及生化指标的影响,选取25日龄断奶的"大×长"二元杂交仔猪150头,随机分为对照组、抗生素组、Ⅰ组、Ⅱ组和Ⅲ组,每组3个重复,每个重复10头,对照组喂养基础日粮,抗生素组在基础日粮中添加100mg/kg泰乐菌素,其余3组分别在基础日粮中添加1 000mg/kg太子参茎叶多糖、枯草芽孢杆菌、太子参茎叶多糖+枯草芽孢杆菌。试验期30d。结果表明:(1)与对照组相比,抗生素组、Ⅰ组和Ⅲ组平均日增重(ADG)极显著增加(P<0.01),Ⅱ组ADG显著增加(P<0.05);各试验组仔猪腹泻率均极显著降低(P<0.01);(2)Ⅰ、Ⅱ组IgA、IgM显著增加(P<0.05),Ⅲ组IgA、IgM和IgG极显著增加(P<0.01);(3)Ⅰ、Ⅲ组C3、C4极显著增加(P<0.01),Ⅱ组C3显著增加(P<0.05);(4)Ⅰ、Ⅱ组IL-2、IL-4、IFN-γ显著增加(P<0.05),Ⅲ组IL-2、IL-4、IFN-γ极显著增加(P<0.01);(5)各试验组白蛋白(ALB)均极显著增加(P<0.01);Ⅰ组尿素氮(BUN)显著降低(P<0.05),抗生素组、Ⅱ和Ⅲ组尿素氮(BUN)极显著降低(P<0.01)。因此,在断奶仔猪日粮中同时添加太子参茎叶多糖与枯草芽孢杆菌可以提高仔猪生长性能及免疫功能,改善血液生化指标,且二者合用效果优于单独添加。This study was conducted to investigate the effects of Radix pseudostellariae stem and leaf polysaccharide（RPSLP） combined with bacillus subtilis on growth performance, immune function and biochemical index of weaned piglets. One hundred and fifty 25-day-old weaned piglets（Large white×Landrace） were selected and randomly allocated into five groups including control group, antibiotic group, group I, II and III, with three replicates per group and 10 piglets per replicate. The control group of piglets were fed a basal diet, and other groups were fed a basal diet supplemented with 100 mg/kg tylosin, 1 000 mg/kg RPSLP, 1 000 mg/kg bacillus subtilis, 1 000 mg/kg RPSLP and 1 000 mg/kg bacillus subtilis for 30 days. The results showed as follows： compared with the control group, the ADG in antibiotic group, group I and III all increased（P〈0.01）, so did group II （P〈0.05）; the diarrhea rate in all groups decreased （P〈0.01）; In aspects of IgA,IgG and IgM, the contents of IgA and IgM in group I, II increased （P〈0.05）,the content of IgA, IgG and IgM in group III increased （P〈0.01）; In aspects of C3 and C4,the contents of C3 and C4 in group I, III increased （P〈0.01）,the contents of C3 and C4 in group II increased （P〈0.05）;In aspects of IL-2, IL-4 and IFN-γ, the contents of IL-2, IL-4 and IFN-γ in group I, II increased （P〈0.05）, the contents of IL-2, IL-4 and IFN-γ in group III increased （P〈0.01）;the content of TG in four experimental groups significantly decreased （P〈0.01）; the ALB contents in all groups significantly increased （P〈0.01）; the BUN in antibiotic group, group II and III significantly decreased （P〈0.01） but decreased in group I （P〈0.05）. It was concluded that RPSLP combined with bacillus subtilis in diets could enhance growth performance,immune function and improve biochemical indexes in the weaned piglets and the effect was better than added separately.
