摘　　要：用内蒙古农业大学动物科学和医学学院研制的一种新型复合菌发酵剂饲喂肉仔鸡。饲养试验Ａ 结果表明：添加２％ 的复合菌发酵剂与黄霉素组和对照组相比，分别提高增重２ ．７２ ％ 和６．０％ （ Ｐ ＞ ０ ．０５），提高成活率４．６５％ 和４ ．６５ ％ （ Ｐ＞０ ．０５），提高饲料转化率－ ０．８９ ％ 和２ ．９１％ ，嗉囔ｐＨ 值亦有下降的趋势。饲养试验Ｂ结果表明：添加复合菌发酵剂的试验组与畜禽康乐宁１＃ 、畜禽康乐宁２＃ 、黄霉素及对照组相比分别提高日增重－ ０．９５ ％ 、１．１７ ％ 、０．４１％ 和６ ．０８ ％ （ Ｐ＞ ０ ．０５），提高成活率为－ １．７３ ％ 、３．４５％ 、１．７２％ 和１ ．７２ ％ （ Ｐ＞ ０ ．０５），提高饲料转化率－２ ．４２ ％ 、５ ．３６ ％ 、１ ．４０ ％ 、和８．２３ ％ ，嗉囔ｐＨ 值亦有下降的趋势。Two experiments were conducted to test the effect of complex bacteria leaven (CBL) on broiler growth.The experimental results in trial I showed that the weight gain,livability,feed conversion efficiency(FCE)of broiler in CBL group were 2.72%,4.65%,-0.89% higher than that in flavomycin group and 6.00%,4.65%,2.90% higher than that in control group respectively.Although the difference of pH value in broiler`s crop were not significant between each groups,the CBL group had a lower pH value in crop than other groups.Similar positive effect of CBL on broiler`s weight,livability,FCE were also found in trial II.
