Two experiments were performed to study the effects of feeding broad bean on growth,muscle composition and pre-intestine protease activity of different sizes of grass carp.In Exp.Ⅰ,grass carp with body weight of(535±50) g was fed with formulated diet,immersed or sprouted broad bean for 77 days.In Exp.Ⅱ,grass carp with body weight of(84.5±3.5) g was fed with formulated diet or sprouted broad bean for 68 days.In both trials,fish fed with immersed broad bean or sprouted broad bean had lower growth rate,muscular fat content,pre-intestine protease activity(P0.01) and higher FCR,muscle collagen content(P0.01) than that of fish fed with formulated diet.Results above showed that flesh quality of grass carp could be changed,but growth performance and intestine protease activity decreased by feeding broad bean.
