摘　　要：以血粉复合发酵蛋白(Fermented blood meal protein,FBP)分别等量替代对照组日粮中37.5%、62.5%和100%的鱼粉,研究了FBP对彭泽鲫(Carassius auratus)的生长性能和肝脏功能的影响。结果显示,随着替代比例的增加,彭泽鲫的增重率呈下降趋势,饲料系数依次上升,但替代37.5%鱼粉组的增重率和饲料系数与对照组差异不显著;肠道消化酶活性、肝脏谷丙转氨酶(GPT)、谷草转氨酶(GOT)活性和GPT/GOP比值随替代比例的增加而下降,碱性磷酸酶活性呈上升趋势。在37.5%替代比例下,彭泽鲫肝脏抗氧化能力与对照组差异不显著。本实验说明,FBP替代鱼粉的比例不宜超过37.5%。The experiment was conducted to study the effects of replacing fish meal with different proportions of fermented blood meal protein （FBP） in diet on growth performance and liver function of Pengzc crucian carp （Carassius auratuz）. The equivalent replacement ratio was 37.5% , 62. 5% and 100% , respectively. The activity of protease, amylase and li- pase in intestine and GPT, GOT, GPT/GOT in liver decreased with the increasing of replacement ratio, while ALP in- creased. When the replacement ratio was 37.5% , liver antioxidant ability of crucian carp had no significaut difference from control group. In conclusion, the replacement ratio should be less than 37. 5%.
