摘　　要：[目的]研究微生态饲料添加剂对肉牛增重的影响。[方法]选用健康杂种肉牛40头,随机分为4组,在饲料中分别拌喂3个不同剂量的微生态饲料添加剂,观察其对肉牛的增重效果。[结果]结果表明,混合精料中添加2.0%和1.5%的微生态饲料添加剂,其对肉牛的增重效果显著高于对照组(P(0.05)。[结论]该研究结果为微生态饲料添加剂的推广应用提供科学依据。[Objective] The purpose of this research was to study the effect of micro-ecological feed additives on beef cattle weight.[Method]The healthy hybrid beef cattle were selected and randomly classified into 4 group,the micro-ecological feed additives were added to the feed with the different dosage.The effect of weight gain of beef cattle was observed.[Result] The results showed that the 40 d mixed feed of 2.0% and 1.5% of micro-ecological feed additives,the effect on weight gain of beef cattle was significantly higher than CK（P〈0.05）.[Conclusion] This study will provide the scientific basis for popularization and application of micro-ecological feed additives.
