Abstract: 120 Heilongjing Zi geese were divided into three groups(control and Ⅰ,Ⅱ groups),every group was forty. The control group was base feed,The group Ⅰand Ⅱ were appended 1.5 ml/kg、1.0 ml/kg microecological products daily for 90 d in base feed. The result indicated: Compared with the control,the number of lactobacillus in the experimentsⅠ,Ⅱ caecum were all more significant(P<0.05), the number of Enterobacillus and Salmonella were all much fewer (P<0.05);The same experimental group had no significiant difference (P>0.05).The experiments daily consuming feed and fresh propotion had significiant difference compared with the control (P<0.05). The experiment showed that the microecological Pruducts had the function of regulating the important flora with impact on caecum, and increased the immune function and growth performance.
