摘要
本试验应用内蒙古农业大学动物科技学院研制的新型复合菌发酵剂饲喂肉鸡,试验结果表明:添加复合菌发酵剂的试验组与黄霉素及对照组相比分别提高日增重0 .41 % 和6 .08 % ( P> 0 .05) , 提高成活率为1 .72 % 和1 .72 % ( P> 0 .05) ,提高饲料转化率1 .40 % 和8 .23 % 。代谢试验结果表明:在育雏期,各试验组间以及试验组和对照组之间在营养物质吸收上的差异均不显著( P> 0 .05) 。在育成期,各试验组间及试验组与对照组间在粗脂肪、无 N 浸出物利用上差异不显著( P> 0 .05) ;在粗蛋白、 Ga 、 P 的利用上,复合菌发酵剂组与黄霉素组差异不显著( P> 0 .05) ,但显著高于对照组( P< 0 .05) 。
The effect of complex bacteria leaven(CBL) on nutritious utilization in Broiler was studied. The results showed that the weight gain,livability (feed conversion efficiency)of broiler in CBL group were 0.41%, 1.72% ,1.40% higher than that in flavomycin group and 6.08%,1.72%,8.23% higher than that in control group respectively.The metabolism experiment results also indicated that the CBL could significantly increased the utilization of crude protein,crude fiber,Ca and P in growing broiler,compared with control group.
