Abstract: A total of 405 one-day-old Cherry valley ducks were chosen to evaluate the effects of Bacillus coagulans and Enterococcus faecalis on growth performance of Cherry valley duck. Ducks in the control group were fed a basal diet,and the other two test groups were fed basal diet supplemented with B. coagulans and E. faecalis,respectively. The results showed as follows：at the first week,the body weight of B. coagulans group was very significantly lower than that of E. faecalis group and control group（P<0.01）,the daily feed intake of B. coagulans group significantly higher than that of control group（P<0.05）. The daily feed intake of the two test groups were very significantly lower than that of control group at the 6th week（P<0.01）; the average survival rates of the two test groups were significantly higher than that of control group（P<0.05）; the average daily feed intake and feed/gain of the two test groups were lower than that of control group, but the difference was not significant（P>0.05）. In conclusion,dietary supplemented with B. coagulans and E. faecalis can reduce the daily feed intake,decrease the feed/gain, and improve the survival rate.
