微生态制剂对小尾寒羊羔羊育肥性能的影响

目的]为微生态制剂在肉羊生产中的应用提供理论依据.方法]以小尾寒羊为试验对象,研究微生态制剂对小尾寒羊羔羊育肥性能的影响.结果]试验期内试验组和对照组小尾寒羊羔羊的平均增重分别为18.86和16.09 kg,试验组增重比对照组高17.22％,差异显著（P＜0.05）.试验组和对照组平均日增重分别为209.56和178.78 g.试验组体尺和屠宰性能均比对照组有不同程度提高.结论]在日粮中添加微生态制剂可以提高小尾寒羊对饲料的利用效率,改善小尾寒羊的育肥性能,具有较大的推广价值.

Study on the Effects of Micro-ecological Preparation on the Fattening Performance of Small-tail Han Sheep Lamb

Objective] The research aimed to provide theoretical basis for the application of micro-ecological preparation in the production of meat sheep.Method] Taking Small-tail Han Sheep as experiment object,the effects of micro-ecological preparation on the fattening performance of Small-tail Han Sheep were studied.Result] During the test period,the average weight gain of Small-tail Han Sheep in test group and control group were 18.86 and 16.09 kg respectively.The weight gain in test group was increased by 17.22% than that of control group,with significant difference（P 〈 0.05）.The average daily gain in test group and control group was 209.56 and 178.78 g respectively.The body size and slaughter performance in test group increased than that of control group.Conclusion] Adding micro-ecological preparation in the diet could enhance the feed utilization rate of Small-tail Han Sheep and improve the fattening performance of Small-tail Han Sheep,with greater popularization values.
