摘　　要：为研究全混合日粮中添加活性酿酒酵母及葡萄糖对母羊血清生化指标及瘤胃发酵参数的影响。选取30只健康无病的母羊,随机分为3组,每组10个重复,分别为对照组、酵母组和葡萄糖组。对照组母羊饲喂基础日粮,酵母组及葡萄糖组在基础日粮中分别添加0.5%的活性酿酒酵母以及1.0%的葡萄糖。试验期为64 d。结果显示,各组间母羊血清生化指标无显著差异(P>0.05);与对照组相比,葡萄糖组丙酸和总挥发性脂肪酸(TVFA)含量显著提高,乙丙比显著降低(P<0.05)。研究表明,母羊日粮中加入1%葡萄糖更有益于瘤胃发酵。The experiment was to study the effect of adding active Saccharomyces cerevisiae and glucose to the total mixed diet on serum biochemical indexes and rumen fermentation parameters of ewes. 30 healthy and disease-free ewes were randomly divided into three groups with 10 replicates in each group, namely the control group, the yeast group and the glucose group. The ewes in control group were fed with basal diet, and the yeast group and the glucose group were supplemented with 0.5% active Saccharomyces cerevisiae and 1.0% glucose in the basal diet, respectively. The experiment lasted for 64 d. The results showed that there was no significant difference in serum biochemical indicators between the groups(P>0.05). Compared with the control group, the content of propionic acid and total volatile fatty acid(TVFA) in glucose group was significantly increased, and the ethylene-propylene ratio was significantly reduced(P<0.05). The experiment indicates that adding 1.0% glucose in the diet of ewes is beneficial to rumen fermentation.
