摘要
试验旨在研究微生态制剂对育肥羔羊生长性能、养分表观消化率和血液生化指标的影响。选用180只体重(20.45±0.77)kg的育肥羔羊,随机分为3组,每组3个重复,每个重复20只。对照组饲喂基础日粮,试验Ⅰ、Ⅱ组在基础日粮中分别添加0.1%、0.2%微生态制剂,试验期30d。结果显示,试验Ⅰ、Ⅱ组的平均日增重分别比对照组提高了12.88%(P<0.05)和7.36%(P>0.05);平均日采食量虽有所升高但差异均不显著(P>0.05);料重比分别比对照组降低了6.50%和6.00%(P<0.05)。日粮中添加微生态制剂可显著提高有机质、粗蛋白质和酸性洗涤纤维的表观消化率(P<0.05);试验Ⅰ、Ⅱ组血清中尿素氮含量显著低于对照组(P<0.05),血糖含量显著高于对照组(P<0.05),但血清总蛋白、白蛋白、总胆固醇和甘油三酯的含量试验组与对照组相比差异均不显著(P>0.05)。结果表明,日粮中添加微生态制剂可提高羔羊生长性能和营养物质表观消化率,降低血清尿素氮含量,提高血糖含量,0.1%添加组优于0.2%添加组。
The experiment was conducted to study the effects of compound probiotics on growth performance, apparent digestibility and serum biochemical traits of finishing sheep. One hundred and eighty finishing sheep with an average body weight of （20.45±0.77）kg were randomly divided into 3 groups with 3 replicates per group of 20 sheep per replicate.The control group was fed the basal diet, the groups Ⅰ and Ⅱ were fed the basal diet in which 0.1% and 0.2% compound probiotics were supplemented. The experiment lasted for 30 d. The results showed that the average daily gain of the experiment groups Ⅰ and Ⅱ were both higher than that of the control group, higher above 12.88％ （P〈0.05） and 7.36％ （P〉0.05） respectively, and the average daily feed intake in experiment groups was higher than that of the control group（P＞0.05）.The number of F/G in experiment groups Ⅰ and Ⅱ were lower 6.50% and 6.00% than that of the control group（P〈0.05）. The apparent digestibility of organic matter, crude protein and acid detergent fiber were significantly increased in the experiment groups （P＜0.05）. The BUN in the serum of the experiment groups Ⅰ and Ⅱ were significantly lower than that of the control group（P＜0.05）, the Glu were significantly higher than that of the control group（P＜0.05）. But the effect on other blood indices was similar to that of the control group （P＞0.05）. It concluded that feeding compound probiotics could improve the growth performance and apparent digestibility of nutrients, reduce the contents of BUN in serum, increase the contents of Glu in serum of finishing sheep, and better effect was obtained in the group of 0.1% compound probiotics.
