摘　　要：通过十二指肠灌注不同剂量酵母培养物,探讨其对绵羊血液生化指标、免疫及抗氧化功能的影响。选用9只体况良好、体质量相近,装有十二指肠瘘管的小尾寒羊,随机分3组,每组3个重复,每个重复1只羊。分别在基础日粮条件下于十二指肠分期灌注占日粮干物质0.0%,1.5%,2.0%的酵母培养物。结果表明,十二指肠灌注酵母培养物能显著提高绵羊血清GLU、T-AOC和T-SOD含量(P<0.05),而MDA含量显著降低(P<0.05);同时还能提高血清IgG、IL-6、IL-2和IFN-γ含量(P<0.05)。综合各项指标分析,十二指肠灌注酵母培养物对绵羊血液糖、蛋白质代谢相关指标影响不大,但在一定程度上提高抗氧化酶活性以及IgG、IL-2和IFN-γ含量。To study the effect of different dose of yeast culture through duodenum perfusing on blood biochemical indexes,immune and antioxidation,nine sheep with the same body weight,fitted with duodenum fistula were divided into three treatments,with 3replications of 1sheep each,and respectively duodenum infusing 0.0%,1.5% and 2.0% of yeast culture on the basis of DM of the basal diets.The results showed that the concentrations of GLU,T-AOC and T-SOD in serum had a significantly increase（P〈0.05）,and decrease in MDA（P〈0.05）.There was a significant increase in IgG,IL-6,IL-2and IFN-γ（P〈0.05）.By comprehensive analysis,perfusing yeast culture in duodenum has no effect on glucose and protein metabolism of blood,but can increase the activity of antioxidant enzymes and the content of IgG,IL-2and IFN-γ.
