摘要
试验结果表明,试验组猪群的猪瘟抗体水平、日增重、死淘率、饲料报酬和经济效益均明显优于对照组,在3个试验组中,尤以1.5%添加量效果最佳。试验组平均日增重421g,比对照组提高30.75%;饲料转化率平均为2.02∶1,比对照组提高10.62个百分点;成活率平均98.3%,比对照组提高13.3个百分点;头均公斤增重成本2.60元,比对照组降低26%。
The experimental results showed that the hog cholera antibody level,daily gain,cast-for-death rate,feed efficiency and economic benefits of the experimental groups were significantly better than those of the control group.Among three experimental groups,the group with 1.5% level was the most desirable.The average daily gain for the experimental groups were 421 gram,which was 30.75% higher than the 332 gram in the control;and the mean feed efficiency and survival rate were 2.02∶1 and 98.3% which were 10.62% and 13.3% higher than those 2.26∶1 and 85.0% of the control respectively.The cost for per kilogram weight gain for each pig was (2.60) Chinese yuan,which was 26% lower than 2.93 of the control group.
