Five diets, including complete formula diet (control), soaked broad bean (SBB, fed as crumbled pieces after immersionin water), broad bean, common vetch seed and bitter melon seed diets (BBD, CVD, BMD), which included 75% broad bean, 60% common vetch seed and 60% bitter melon seed in formula diet, respectively, were fed to juvenile grass carps with an initial body weight of (59.0±0.6) g. After 8 weeks of feeding, the control fish had the highest weight gain (WG) and lowest feed conversation ratio (FCR) among all groups (<0.05). Compared with the SBB group, the WG was 56.9% in the BBD group, and -30.6% and -21.2% in the CVD and BMD groups (<0.05), respectively. Muscle collagen contents of the SBB, BBD, CVD and BMD groups were significantly higher, while muscle lipid contents were significantly lower than those of the control (<0.05). The BMD group had higher total amino acids and delicious amino acids contents in muscle than those of the control and SBB groups (<0.05). The hepatopancreatic superoxide dismutase (SOD) activities of fish fed the BBD, CVD and SBB diets were significantly lower (<0.05), and hepatopancreatic malonaldehyde (MDA) content and muscle creatine kinase (CK) activity were higher than those of fish fed the control diet (<0.05). However, fish fed the BBD diet had lower hepatopancreatic MDA than fish fed the SBB diet. Fish fed the BBD, CVD, BMD and SBB diets had a lower lipidase activities and a higher amylase activities in their intestines compared with the control fish (<0.05). The fish fed the BBD, CVD and SBB diets also showed lower protease activities than the control (<0.05). In conclusion, soaked broad bean and high levels of dietary broad bean, common vetch seeds and bitter melon seed saltered the muscle composition of grass carp, and significantly decreased their growth performance. For growth and muscle composition, a broad bean diet has more advantages in the culture of crisped grass carp than common vetch seed, bitter melon seed and soaked broad bean diets.
