摘要
试验选取体重25kg左右的健康“杜×长×大”猪180头，随机分为6组，对照组饲喂基础日粮，试验I、Ⅱ、Ⅲ、Ⅳ、V组分别在基础日粮中添加核肽素（HTS）2kg／t、好力高（HLG）150g／t、动力源（DLY）150g／t、新霉素（XMS）150g／t、肠乐美（丁酸梭菌制剂）150g／t，试验期42d。试验结果显示：试验V组较对照组和其他各试验组日增重分别提高了13．70％、25．62％、12．18％、11．85％、6．49％；料重比分别降低了7．96％、4．59％、8．37％、8．77％、5．02％；试验V组生长猪每千克增重的成本最低，较对照组和其他各试验组分别降低了10．63％、7．30％、18．94％、10．85％、10．17％。这表明，生长猪日粮中添加150∥t的肠乐美较对照组和其他各试验组提高了生长猪的日增重，降低了料重比，同时，大大节约了养殖成本。
180 health growing pigs （Duroc×Landrace×Yorkshire） with an average initial body weight of 25kg were randomly allocated to 6 groups by weigth and sex. The control group was fed with basal diet. Test group Ⅰ , Ⅱ , Ⅲ, Ⅳ was fed with basal diet added 2kg/t HTS, 150g/t HLG, 150g/t DLY, 150g/t XMS, 150g/t Butytics （Clostridium butyricum） respectively. The feeding experiment lasted for 42 days. Results of the experiment indicated that, compared to the control group and other test groups, test group V improved the average daily gain by 13.70%, 25.62%, 12. 18%, 11.85%, 6.49% respectively, decreased feed/gain ratio by 7.96%, 4.59%, 8.37%, 8.77%, 5.02% respectively, and decreased the cost of per kg weight gained by t0.63%, 7.30%, 18.94%, 10.85%, 10.17% respectively. This suggested that adding 150g/t Butytics to the growing pig diets could improve the daily gain weight of growing pigs, reduce feed/gain ratio, and significant save the feeding cost compared with the control group and other test groups.
