【摘要】:為研究日糧中同時添加太子參莖葉多糖與枯草芽孢桿菌對斷奶仔豬生長性能、血清免疫指標及生化指標的影響,選取25日齡斷奶的"大×長"二元雜交仔豬150頭,隨機分為對照組、抗生素組、Ⅰ組、Ⅱ組和Ⅲ組,每組3個重復(fù),每個重復(fù)10頭,對照組喂養(yǎng)基礎(chǔ)日糧,抗生素組在基礎(chǔ)日糧中添加100mg/kg泰樂菌素,其余3組分別在基礎(chǔ)日糧中添加1 000mg/kg太子參莖葉多糖、枯草芽孢桿菌、太子參莖葉多糖+枯草芽孢桿菌。試驗期30d。結(jié)果表明:(1)與對照組相比,抗生素組、Ⅰ組和Ⅲ組平均日增重(ADG)極顯著增加(P0.01),Ⅱ組ADG顯著增加(P0.05);各試驗組仔豬腹瀉率均極顯著降低(P0.01);(2)Ⅰ、Ⅱ組IgA、IgM顯著增加(P0.05),Ⅲ組IgA、IgM和IgG極顯著增加(P0.01);(3)Ⅰ、Ⅲ組C3、C4極顯著增加(P0.01),Ⅱ組C3顯著增加(P0.05);(4)Ⅰ、Ⅱ組IL-2、IL-4、IFN-γ顯著增加(P0.05),Ⅲ組IL-2、IL-4、IFN-γ極顯著增加(P0.01);(5)各試驗組白蛋白(ALB)均極顯著增加(P0.01);Ⅰ組尿素氮(BUN)顯著降低(P0.05),抗生素組、Ⅱ和Ⅲ組尿素氮(BUN)極顯著降低(P0.01)。因此,在斷奶仔豬日糧中同時添加太子參莖葉多糖與枯草芽孢桿菌可以提高仔豬生長性能及免疫功能,改善血液生化指標,且二者合用效果優(yōu)于單獨添加。
[Abstract]:In order to study the effect of adding polysaccharide from stem and leaf of Panax miltiorrhiza and Bacillus subtilis on growth performance, serum immune index and biochemical index of weanling piglets, 150 weaned piglets of "big 脳 long" binary hybrid at 25 days old were selected. They were randomly divided into three groups: control group, antibiotic group, 鈪,
