| 摘 要： | 选用初体重25．74-33．53g的正常健康鲤，经α-二甲基异莰醇(2-methylisobomeol，MIB)人工染味后，用含L-肉毒碱分别为0、50、100、150、200、250mg／kg的配合饲料投喂60d。结果表明：用添加了L-肉毒碱的饲料投喂鲤，可以明显去除人工染味鲤体内的异味，使之达到人的味觉能接受的程度；鲤摄食含L-肉毒碱100mg／kg的饲料后，可显著促进其生长；摄食添加L-肉毒碱饲料的鲤，其血液中超氧化物歧化酶(SOD)的活性明显比对照组鱼的高，而谷丙转氨酶(GPT)的活性明显比对照组鱼的低，说明L-肉毒碱可减缓MIB对鲤的伤害。

| Abstract: | Common carp Cyprinus carpio L. juveniles with body weight of 25.74-33.53 g were fed diets supplemented with L-carnitine at a rate of 0, 50, 100, 200, and 250 mg/kg diet for 60 days. The results showed that the fish fed the diet containing 100 mg/kg feed L-carnitine had less off-flavor than the fish fed the diet without supplementation of L-carnitine. It was found that L-carnitine improved the growth rate, and inhibit the 2 methylisoborneol impact on the fish activity. There were high superoxide dismutase (SOD) activity, and low glutamic-pyruvic transaminase (GPT) activity in the fish fed the diet supplemented with the chemical. |
