摘 要：A growth trial was conducted on juvenile fish with initial body weight of(22.40±0.30) g for 8 weeks at controlled temperature(22±3)℃in single recirculating *** meal and dehulled soybean meal were used as protein *** isonitrogenous(40%protein) and isoenergetic (15.8MJ·kg) diets,with dehulied soybean meal replacing level 0,15,30,45 and 60%of fish meal protein,were formulated to feed juveniles to investigate the effects of dietary soybean protein level growth,body composition and main blood biochemical parameters of clarias lazera. The results indicated that there were no significant differences(P0.05) in specific growth rate among fish fed the diets containing different groups dehulled soybean meal levels ranging from 30%to 60%with control groups;When replaced level reached 60%,protein efficiency rate and productive protein value were significant(P0.05)by dehulied soybean meal *** dehulled soybean meal replaced fish meal by 60%,the protein content in muscle was significantly decreased(P0.05) by dehulied soybean meal *** soybean meal have no effects(P0.05 ) on the concentration of blood glucose,urea nitrogen,total cholesterol,triglyceride,total protein,albumin, globulin and the activity of glutamic-oxal(o)acetic transaminase and glutamic-pyruvic ***,the dietary protein content was 40%in compound feed and the dehulled soybean meal of replacement level was 45%in the diet could be recommended for optimum growth and efficient feed utilization of juvenile clarias lazer.
