Ltd; 3Xingdian Animal Husbandry and Veterinary Station,Xinzheng,Henan） Abstract: Effects of clostridium butyricum on performance of breed ducks were investigated. 10-month-old breeding Muscovy ducks (n=840) were randomly divided into 2 treatment groups. Ducks fed basal diet were the control group, and ducks fed experimental diet (basal diet supplemented with 0.2% probiotics) were the experimental group. The experiment was terminated after 34 days. The average laying rate of ducks in experimental group was 85.847%, and was significantly higher (P0.05) than that of control group by 4.906%. The fertilization rate of experimental group was 100.00%, and was extremely significantly (P0.01) higher than that of control group by 28.58%. As for the other egg qualities, no differences were observed between the 2 treatment groups(P0.05). The results suggest that clostridium butyricum can increase the laying rate and fertilization rate of breed ducks effectively.
