主　　题：Chicken haemoglobin meal Growth Feed utilization Non-specific immunity Largemouth bass 

摘      要：A 12-week feeding trial was conducted to evaluate the effects of replacing fish meal by chicken haemoglobin powder in largemouth bass *** isonitrogenous(48%)and isolipidic(12%)diets were formulated to replace 0%(control),9.80%,19.61%and 29.41%of fish meal with chicken haemoglobin *** diet was fed to triplicate groups of fish(initial weight:49.50±0.07 g)twice *** fish specific growth rate was significantly reduced when diet replacement level was up to 19.61%,which may be related to the feed intake and apparent digestibility coefficient of protein and amino ***,the feed efficiency ratio and protein efficiency ratio were not significantly decreased until the replacement level up to 29.41%.The activity of CCP was significantly reduced when 19.61%of fish meal was ***,the activity of lysozyme and serum protein content was significantly altered in fish fed with the diets up to 29.41%***,the red blood cell count and haemoglobin content was significantly decreased when the replacement level was up to 19.61%.In overall,the diet with 9.80%of chicken haemoglobin powder was more suitable for largemouth bass.
