摘　　要：为降低水产配合饲料对鱼油和豆油的依赖,开发新型脂肪源,本研究配制5种不同脂肪源的等氮等脂(48%粗蛋白质,12%粗脂肪)配合饲料(D1~D5),其中D1的脂肪源为复合油1(罗非鱼油∶豆油=1∶1)、D2为复合油2(亚麻籽油∶豆油=1∶2)、D3为复合油3(鱼油∶棉籽油∶棕榈油∶亚麻籽油=3∶3∶3∶1)、D4为罗非鱼油、D5为豆油。以上述饲料分别在室内循环系统中对应投喂5组初始体重为(112.09±0.15)g的杂交鳢(Channa argus×Channa maculate♀)幼鱼60 d。结果显示:在生长性能和肌肉常规营养成分含量方面,各组均无显著差异(P>0.05);在生化指标方面,饲料脂肪源对血清碱性磷酸酶活性和肝脏总抗氧化能力以及血清、肝脏、肠道丙二醛含量均无显著影响(P>0.05),对其他生化指标有显著影响(P<0.05),其中D3组血清总胆固醇、甘油三酯和低密度脂蛋白含量与肝脏甘油三酯和粗脂肪含量最低,血清总抗氧化能力和高密度脂蛋白含量,血清、肝脏和肠道酸性磷酸酶、超氧化物歧化酶和过氧化氢酶活性以及肠道碱性磷酸酶活性最高;在肌肉品质方面,D3组肌肉中C20∶5n-3(EPA)、C22∶6n-3(DHA)含量以及肌肉的咀嚼性、胶着性最高,其中EPA含量显著高于其他各组(P<0.05),DHA含量显著高于D1、D2和D5组(P<0.05),咀嚼性显著高于D2和D4组(P<0.05),胶着性显著高于D1、D2和D4组(P<0.05)。综上所述,在本试验条件下,以复合油3为饲料脂肪源不仅可保证杂交鳢的生长效果,而且可提升其免疫和抗氧化能力,改善肌肉品质。As to reduce the dependence of aquatic compound feeds on fish oil and soybean oil and to develop new lipid sources,five iso-nitrogenous and iso-lipid(48%crude protein,12%crude lipid)compound feeds(D1 to D5)with different lipid sources were formulated in this study,of which D1 lipid source was compound oil 1(tilapia oil∶soybean oil=1∶1),D2 was compound oil 2(linseed oil∶soybean oil=1∶2),D3 was compound oil 3(fish oil∶cottonseed oil∶palm oil∶linseed oil=3∶3∶3∶1),D4 was tilapia oil,and D5 was soybean oil.The above diets were used to breed juvenile hybrid snakehead(Channa argus×Channa maculate♀)with initial body weight of(112.09±0.15)g of five groups in an indoor recirculation system for 60 days,respectively.The results showed that:in terms of growth performance and muscle conventional nutritional component contents,there were no significant differences among all groups(P>0.05).With regard to biochemical indexes,there were no significant differences in serum alkaline phosphatase activity,liver total antioxidant capacity and the malondialdehyde content in serum,liver and intestine of fish in all groups(P>0.05),but had significant effects on other biochemical indexes(P<0.05),in which,D3 group had the lowest serum total cholesterol,triglyceride and low-density lipoprotein contents,liver triglyceride and crude lipid contents,and it had the highest serum total antioxidant capacity and high-density lipoprotein content,serum,liver and intestinal acid phosphatase,superoxide dismutase and catalase activities,as well as intestinal alkaline phosphatase activity.With regard to muscle quality,D3 group fish had the highest muscle C20∶5n-3(EPA)and C22∶6n-3(DHA)contents and muscle chewiness and gumminess,and the EPA content in D3 group was significantly higher than that of other groups(P<0.05),the DHA content was significantly higher than that of D1,D2 and D5 groups(P<0.05),the chewiness was significantly higher than that of D2 and D4 groups(P<0.05),and the gumminess was significantly higher than that of
