摘　　要：选取均重为(20.72±2.68)g的鲤(Cyrinus carpio)270尾,随机分为3个处理,在基础日粮中分别添加0(对照组)、4%、8%的苹果渣,在半封闭的循环水养殖系统饲养51d,分析比较苹果渣对鲤生长性能、血清生化指标和肝胰脏超氧化物歧化酶活性的影响。结果显示,日粮添加苹果渣对鲤生长性能、体成分无显著影响(P>0.05);各组饲料干物质表观消化率分别为70.41%、69.78%、74.13%,组间无显著差异(P>0.05);8%苹果渣组血清谷丙转氨酶活性显著高于对照组和4%苹果渣组(P<0.05),8%和4%苹果渣组血清谷草转氨酶活性和高密度脂蛋白胆固醇浓度均显著高于对照组,各组间血清总蛋白、总胆固醇、甘油三酯、低密度脂蛋白胆固醇和血糖浓度无显著差异(P>0.05);添加苹果渣对鲤肝胰脏超氧化物歧化酶活性无影响。研究表明,在鲤鱼饲料中添加4%、8%苹果渣对生长性能无影响,且能够强化脂质代谢,但较高水平添加可能对肝胰脏造成损伤。建议鲤饲料中苹果渣添加量在4%以下。A total of 270 fish with initial body weight of （20.72±2.68）g were randomly divided into three groups,and fed the basal diets supplementation with apple pomaee level as 0 （control group）,4 %, 8 % ,respectively.The fish was fed for 51 days.The effect of apple pomaee on growth performance,serum biochemical indexes and the activity of superoxide dismutase in hepatopanereas were studied.The results showed that there were no significant differences on growth performance,body composition and apparent digestibility of dry matter （70.41%,69.78 %,74.13 %）among groups （P 〉 0.05）. The addition of apple pomaee to diets had no influence on blood total serum protein,total cholesterol （Chol）,triglyeeride （TG） ,low density lipoprotein cholesterol （LDL-C）and glucose （GLU）level in the serum,but significantly improved the contents of the high density lipoprotein cholesterol （HDL-C）and the activities of serum glutamie-oxaloaeetie transaminase （GOT） ,glutamate-pyruvate transaminase （GPT）.The levels of HDL-C and GOT of fish fed 4 % and 8 % apple pomaee diet were significantly higher than those of control group, and the GPT of fish fed 8 % apple pomaee diet was significantly higher than those of the control group and the fish fed 4 % apple pomaee diet.The addition of apple pomaee had no significant influence on the activities of superoxide dismutase（SOD）of hepatopanereas.It could be concluded that the addition of 4 % ,8 % apple pomaee to diets of Cyrinus earpio had no influence on growth performance and enhanced lipid metabolism,but it might damage the hepatopanereas with high level dietary apple pomaee addition.It was suggested that the level of dietary apple pomace for Cyrinus carpio should be below 4 %.
