摘要
[目的]为了探索EM（有益微生物群）制剂在养殖业中的应用效果。[方法]在肉牛育肥场，用EM制剂分别对育肥肉牛所用的粗饲料和饮水进行了处理，研究设计了三种育肥方式，选用12～15月龄、未经阉割、膘情基本一致、体重接近的西杂公牛18头，随机分为3组，在精料完全相同的情况下，进行饲喂试验。[结果]表明试验I组与对照组相比，日采食量提高了13．33％，日增重提高了15．65％，增重成本下降了8．21％，效益比较显著；用1000倍EM稀释液饮水，效果不明显，有待于进一步探讨。[结论]说明不同EM处理玉米芯粒育肥试验有不同的效果。
To investigate the effects of EM products on animal industry, the roughage and water for finishing beef cattle were treated by EM products and used in Cattle Fattening Farm. 18 helds of 12--15 month--old Simmental crossbred bulls with consistent fatness and nearly weight which were not castrated were divided into 3 groups and fed with same concentrate. Compared with control, daily intake and daily gain were increased for 13.33% and 15.65%, feeding cost was decreased for 8.21%. No significant effect were observed of the group drinking 1000 times diluted EM products, it needed to be further investigated. It was showed that different results were obtained in feeding cornbcob treated with different methods.
