摘    要:在基础料中分别添加4%的鱼油、豆油、猪油、花生油和混合油(鱼油、豆油、猪油质量比为3∶4∶3),制成5种等氮试验饲料,饲喂初始体质量为(6.04±0.05) g 的异育银鲫60 d,以考察5种脂肪源对异育银鲫形体指标和血清生化指标的影响.结果表明:猪油组的肝体指数与脏体指数均最高,猪油组肝体指数显著高于鱼油组,猪油组脏体指数显著高于混合油组(P<0.05);各试验组鱼体肥满度差异不显著(P>0.05);各试验组总蛋白(TP)含量和白蛋白(ALB)含量的变化趋势相似,均为鱼油组显著高于猪油组(P<0.05),其余各组之间差异不显著(P>0.05);各试验组谷草转氨酶(AST)活性和谷丙转氨酶(ALT)活性的变化趋势相似,均为猪油组显著高于鱼油组(P<0.05),其余各试验组之间差异不显著(P>0.05);鱼油组甘油三酯(TG)含量最低,豆油组其次,均显著低于混合油组(P<0.05);鱼油组高密度脂蛋白(HDL–C)含量最高,花生油组其次,均显著高于猪油组(P<0.05);各试验组球蛋白(GLB)、胆固醇(CHO)、葡萄糖(BGLU)、低密度脂蛋白(LDL–C)、皮质醇、胰高血糖素(Glu)和胰岛素(Ins)的含量和碱性磷酸酶(AKP)活性差异不显著(P>0.05).在本试验5种脂肪源中,鱼油对异育银鲫形体与血液生化指标的作用效果最好,豆油、花生油和混合油其次,猪油最差

Abstract:To investigate the effect of dietary lipid on the body and blood biochemical parameters of Carassius auratus Gibelio,five diets containing 4% of either fish oil,soybean oil,lard,peanut oil or mixed oil(fish oil∶soybean oil∶lard=3∶4∶3) were fed to five groups of fish(average initial weight(6.04±0.05) g) respectively for 60 d.The results showed that the hepatosomatic index(HSI) and visceral-somatic index in lard group were the highest with HSI significantly higher than that in fish oil group and with visceral-somatic index significantly higher than that in mixed oil group(P<0.05).There was on significant difference in condition factor among different groups(P>0.05).The contents of total protein(TP) and albumin(ALB) shared the same change pattern with those significantly higher in fish oil group than in lard group(P<0.05) and with no significant difference among other groups(P>0.05).The activity change of glutamic oxaloacetic transaminase(AST) was similar to glutamic pyruvic transaminase(ALT),which were both significantly higher in lard group than in fish oil group(P<0.05) and no significant difference was observed among other groups(P>0.05).The concentration of triglyceride(TG) in fish oil group was the lowest followed by that in the soybean oil group,which were both significantly lower than that in mixed oil group(P<0.05).The concentration of the high density lipoprotein-cholesterol(HDL-C) in fish oil group was the highest followed by peanut oil,which were both significantly higher than that in lard group(P<0.05).As for GLB,total cholesterol(TC),blood glucose(BGLU),low density lipoprotein-cholesterol(LDL-C),alkaline phosphatase(AKP),cortisol,insulin(Ins) and glucagons(Glu),there was no significant change among five groups(P>0.05).These results explicated that the fish oil was the best suitable lipid source followed by soybean oil,peanut oil and mixed oil,while lard was the least suitable.
Keywords:Carassius auratus Gibelio  dietary lipid source  morphology  blood biochemical index
