摘　　要：本试验旨在探究饲料中添加裂壶藻粕对花鲈生长性能、非特异性免疫力和抗氧化能力的影响,为裂壶藻粕在花鲈饲料中的应用提供理论依据。在粗蛋白质含量为44%、粗脂肪含量为11%的基础饲料配方基础上,分别以0(对照)、0.8%、1.6%、2.4%、3.2%的裂壶藻粕替代等量面粉配制5种试验饲料,投喂初始规格一致[体重(2.81±0.02)g]的花鲈,养殖周期为60 d。结果显示:花鲈的增重率和特定生长率随着裂壶藻粕添加量的提高呈现先升高后降低的趋势,均在添加量为1.6%时达到最高;与对照组相比,饲料中添加1.6%和3.2%的裂壶藻粕显著提高了花鲈的增重率和特定生长率(P<0.05)。与对照组相比,饲料中添加不同水平裂壶藻粕均显著降低了花鲈肌肉的粗脂肪含量(P<0.05)。与对照组相比,饲料中添加0.8%、1.6%、3.2%裂壶藻粕均显著降低了花鲈血清中甘油三酯含量以及谷丙转氨酶和谷草转氨酶活性(P<0.05)。与对照组相比,饲料中添加1.6%、2.4%、3.2%裂壶藻粕显著升高了花鲈血清中酸性磷酸酶活性(P<0.05),添加2.4%裂壶藻粕还显著升高了花鲈血清中免疫球蛋白M含量(P<0.05)。与对照组相比,饲料中添加1.6%裂壶藻粕显著提高了花鲈肝脏中过氧化氢酶、超氧化物歧化酶和谷胱甘肽过氧化物酶活性(P<0.05),显著降低了肝脏中丙二醛含量(P<0.05)。综上所述,饲料中添加1.6%裂壶藻粕可以促进花鲈的生长,同时提高机体非特异性免疫力和肝脏抗氧化能力。The aim of this experiment was to investigate the effects of dietary supplementation with Schizochytrium meal on the growth performance,non-specific immunity and antioxidant capacity of Lateolabrax maculatus,and to provide a theoretical basis for the application of Schizochytrium meal in the diet of Lateolabrax japonicus.On the basis of a basal diet formula with 44%crude protein and 11%crude lipid,five experimental diets were formulated with 0(control),0.8%,1.6%,2.4%and 3.2%Schizochytrium meal to replace the same amount of wheat flour.Five experimental diets were fed to Lateolabrax japonicus with the same initial size[body weight(2.81±0.02)g]for 60 days.The results showed that the weight gain rate and specific growth rate of Lateolabrax japonicus increased at first and then decreased with the increase of Schizochytrium meal,and dietary supplementation with 1.6%and 3.2%Schizochytrium meal significantly increased the weight gain rate and specific growth rate compared with the control group(P<0.05).Compared with the control group,dietary supplementation with different levels of Schizochytrium meal significantly decreased the crude lipid content in the muscle of Lateolabrax japonicus(P<0.05).The serum triglyceride content,alanine transaminase and aspartate transaminase activities of Lateolabrax japonicus fed diets supplemented with 0.8%,1.6%and 3.2%Schizochytrium meal were significantly lower than those of the control group(P<0.05).The serum acid phosphatase activity of Lateolabrax japonicus fed diets supplemented with 1.6%,2.4%and 3.2%Schizochytrium meal was significantly higher than that of the control group(P<0.05),and dietary supplementation with 2.4%Schizochytrium meal also significantly increased the serum immunoglobulin M content of Lateolabrax japonicus(P<0.05).Compared with the control group,the activities of catalase,superoxide dismutase and glutathione peroxidase in the liver of Lateolabrax japonicus were significantly increased(P<0.05),while the content of malondialdehyde in the liver was significantly d
