The results showed that:(1) The relative weight gain, special growth rate, feed conversion rate, feed protein efficiency and protein deposition rate were improved significantly (P.05) by supplementing compound acidifier in common carp diet.(2) The protease activities in the liver pancreas, fore and middle intestines increased significantly (P.05) by supplementing 0.3% compound acidifier. The activities of amylase and lipase were improved after the supplementation, but not at significant level.(3) Supplementation of compound acidifier in common carp diet did not significantly affect the fish body protein, lipid, ash, moisture contents, coefficient of fatness and viscerosomatic index.
