摘　　要：为研究丁酸梭菌对肉羊生产性能、血清生化指标及瘤胃内环境的影响,试验选取30只杜湖杂交羊随机分为2组,每组3个重复,每个重复5只羊。对照组饲喂基础日粮,试验组在基础日粮中添加200 mg/kg的丁酸梭菌。试验期60 d。结果表明:与对照组相比,试验组肉羊的平均日增重显著提高(P<0.05),料肉比显著降低(P<0.05);试验组血清中白蛋白/球蛋白(ALB/GLB)显著高于对照组(P<0.05);两组相比瘤胃液中挥发性脂肪酸含量差异不显著(P>0.05),试验组瘤胃液中的淀粉酶活性显著低于对照组(P<0.05)。综上,饲粮中添加丁酸梭菌提高了肉羊的生产性能,对肉羊瘤胃内环境没有显著影响。This experiment was conducted to study the effects of Clostridium butyricum on growth performance,serum biochemical parameters and rumen environment of mutton sheep.30 Duhu crossbred sheep were randomly divided into 2 groups with 3 replicates in each group and 5 sheep in each replicate.The control group was fed with basal diet,and the experimental group was fed with basal diet supplemented with 200 mg/kg Clostridium butyricum.The experiment was 60 days.The results showed that the average daily gain(ADG)of the experimental group was significantly higher than that of the control group(P<0.05),and the feed conversion ratio was significantly lower than that of the control group(P<0.05).The ratio of serum albumin to globulin(ALB/GLB)in the experimental group was significantly higher than that in the control group(P<0.05).There was no significant difference in the content of volatile fatty acids between the two groups(P>0.05),but the activity of amylase in the rumen fluid of the experimental group was significantly lower than that of the control group(P<0.05).In conclusion,dietary supplementation of Clostridium butyricum improved the performance of mutton sheep,but had no significant effect on rumen environment.
