| 摘 要： | 为探索秸秆不同调制技术, 提高饲料利用率, 选用秸秆专用复合酶制剂和酵母活菌制剂用清水稀释后喷洒在秸秆表面, 与日粮其他成分充分混匀后饲喂肉牛, 研究对肉牛生产性能和养殖效益的影响。结果表明：经酵母活菌制剂处理的试验Ⅱ组肉牛平均日增重显著（P<0.05）高于经复合酶制剂处理的试验Ⅰ组和对照组, 试验Ⅱ组肉牛每千克体增重的饲料成本比试验Ⅰ组和对照组分别低0.91元和1.83元。试验得出如下结论：酵母活菌制剂处理玉米秸秆对肉牛生长性能具有明显的改善作用, 可以提高肉牛养殖效益。

| Abstract: | The aims of this study were to explore a new technique of corn straw modulation and to improve the diet utilization rate. A feeding experiment was carried out in beef cattle using the diets based on corn straw fermented with compound enzyme preparation （experimental groupⅠ） and live yeast preparation (experimental groupⅡ). The basial diet was served as control. The effects of feeding different diets on production performance and breeding benefits of beef cattle was assessed. The results demonstrated that the experimental groupⅡhad significantly （P<0.05） higher average daily weight gain compared to the experimental group Ⅰand control group, and the feed cost of per kilogram weight gain of the experimental groupⅡwas 0.91 yuan and 1.83 yuan lower than that of the experimental group Ⅰand control group, respectively. In summary, feeding the diets based on corn straw fermented with live yeast preparation significantly improves the production performance of beef cattle, and increase the feeding benefits. |
