摘要
试验于2005年8月在陕西杨凌示范区选择60头18月龄秦川牛进行饲养肥育试验,从日增重、健康状况、饲料转化率、投入产出比几个方面进行了比较,结果发现平均日增重,试验组比对照组提高了34%;健康状况,试验组明显优于对照组;饲料转化率,试验组比对照组提高了29．5%;投入产出比,试验组比对照组增值302．4元,经济效益明显。
The feeding and fattening experiment of 60 Qinchuan cattle at the age of 18 mo. in the fall of 2005 in Yangling of Shaanxi province were conducted to investigate the effect of feeding biological additives on body weight gain, health condition feed efficiency, and ratio of input and output. The result showed that the average daily gain of experimental group increased by 34 % compared with control group ; the better health condition of experimental group was also noticed; the feed efficiency and ratio of input and output for experimental group were 29. 5N and 302.4 yuan （RMB） higher than the corresponding indicators of control group.
