盐霉素和金霉素对育肥猪催肥效果试验

Study of Weight-improving Effects of Salinomycin and Aureomycin on Growing-finishing Pigs

采用单因子试验设计,将70头育肥猪分成两组,试验Ⅰ组31头,试验Ⅱ组39头,Ⅰ组在基础日粮中添加盐霉素40×10-6,Ⅱ组添加金霉素150×10-6。结果表明,Ⅰ组的平均耗料量和料肉比分别比Ⅱ组低4.87%和4.68%,两者差异显著(P<0.05);Ⅱ组的日增重和平均增重分别比Ⅰ组高0.6%和0.29%,两者差异较小;综合经济效益分析结果表明,在育肥猪猪饲料中添加-6盐霉素所创造的经济效益明显大于-6金霉素。

This study was conducted in two pig groups.Group one consists of31pigs while group two consists of39.40×10 -6 Salinomycin was added to basic diet of group one and150×10 -6 auremycin was used for the basic diet of group two.The study result shows that the average feed consumption and feed consumption and feed conversion of group one are respectively4.87%and4.68%lower than that of group two.Difference between the two groups is significant (P<0.05).The study also shows daily gain and average gain of group two are respectively0.6%and0.29%higher than that of group one.This difference betwoen the two groups is very slight.Comprehensive analysis shows that utilization of40×10 -6 salinomycin In the feed additive of growing pigs makes greater economic profit than using of150×10 -6 aureomycin.
