摘要
以初始体重为（7.31±0.12）g的红白锦鲤幼鱼为试验对象,研究虾青素不同添加量（0、100、400、700、1 000、1 300、1 600 mg.kg-1）对锦鲤血液和免疫指标的影响。每组设3个平行,每个平行饲养10尾鱼,表观饱食投喂60 d。结果表明,在饲料中添加700-1 600 mg.kg-1（X3-X6组）虾青素,可显著提高锦鲤血红蛋白含量和红细胞数,在此范围对谷丙转氨酶（ALT）活力无显著影响,添加700 mg.kg-1（X3组）虾青素,可以显著提高锦鲤血糖（GLU）含量,同时,碱性磷酸酶（AKP）活性显著高于对照组。超氧化物歧化酶（SOD）活力在虾青素添加量为400 mg.kg-（1X2组）时,显著低于对照组和除100 mg.kg-（1X1组）外的其他试验组（P〈0.05）。添加虾青素没有对锦鲤乳酸脱氢酶（LDH）和过氧化氢酶（CAT）产生影响。上述研究说明,在饲料中添加虾青素可提高锦鲤免疫功能,综合经济效益角度建议,饲料中虾青素的适宜添加量为700 mg.kg-1。
Abstract： The study was to reasearch effects of dietary axtaxanthin on body pigmentation and growth of ommmental carp （Cyprinus carpio L.） （initial mean body weight： 7.31 ±0.12）. Fish was fed with different axtaxanthin dosage （0, 100,400,700,1 000,1 300,1 600 mg- kg1） and fed to apparent satiety to these groups of 10 fishes for 60 days. The results showed that the numbers of red cells and the hemoglobin content were increased significantly for feeding 700-1 600 mg . kg-1 axtaxanthin while no effects on ALT. The GLU increased obviously in the 700 mg. kg＂ group and the activity of AKP was significantly higher than that in control group. The activity of SOD in X2 group was lower obviously than that in control and other groups except X1 group. No significant effects on LDH and CAT. The results showed that dietary astaxanthin was effective in improving immunity of ornmmental carp and therecommended dietary dosage was 700 mg. kg-1.
