A 45-day feeding trial was performed to investigate the potential growth enhancing effects of three probiotics in common carp(Cyprinus carpio).One hundred and eighty individuals[initial body weight(43.67±0.55) g]were allotted to feed one of the four diets in triplication:a control group without probiotics addition(A)and three treatment groups supplemented with 1000 mg Bacillus subtilis medium per kg diet(B),2500 mg multi Bacillus subtilis culture per kg diet(C),and 100 mg multi-enzyme probiotics per kg diet(D).There were no significant differences in growth performance between the control group and the treatment groups.In comparison with the fish in the control group,however,the fish in the Group B had a better weight gain of 17.09%,feed conversion ratio of 22.03% and protein utilization of 33.11%.Moreover,there were no significant differences in condition factor between the control group and the treatment groups.No significant differences were found in the carcass composition except for ash content.
