复方生态制剂对育肥猪增重效果观察

OBSERVATION ON THE EFFECTS OF INCREASING GROWTH FOR GROWING PIGS WITH CO-PROBIOTICS

采用１２ 株正常动物肠菌群，经微囊化后，组方四个复方生态制剂（１ 、２ 、３ 和４ 组） ，加上基础饲料，饲喂２０ｋｇ～９０ｋｇ 的生长育肥猪。结果显示四个配方对生长育肥猪均有不同程度的增重肥育效果，但其中１ 组对前期（２０ｋｇ ～４０ｋｇ） 增重效果显著，日增重率提高５２．５７ ％ ，Ｐ＜ ０．０５ ；３ 组对后期（４０ｋｇ ～９０ｋｇ） 增重效果显著，日增重率提高２０．４０ ％ ，Ｐ＜ ０．０５ 。由此可推论出：育肥猪前期和后期肠道正常菌群的组成可能不一样，故需补充的生态制剂的菌株也不尽相同，只有补充适当的生态制剂，方能促使动物增重育肥效果显著。

This paper reported the effects of increasing growth for growing pigs with four kinds of co-probiotics In order to choose the better co-probiotics which could increae growth and raise utilizating ration of food obviously The results showed that the all kinds of co-probiotics have the effects of increasing growth for pigs But the fist(R9403+F9406+Ch9401+P9405m) has significant effects for the milking edible pigs(20-40kg) The third (M9301+P9408+DY+DPx) has significant effects for the growing hogs(40-90kg)
