| 摘 要： | 研究了在螺旋藻添加的质量分数为12%时,饲料脂肪水平（5.36%、7.74%、10.52%、12.85%和15.45%均为质量分数）对红白锦鲤Ornmmental carp幼鱼（初始体质量为5.85 g±0.19 g）体色和免疫指标的影响。每组设3个重复,每个重复组饲养10尾锦鲤,表观饱食投喂60 d。结果表明：当饲料中脂肪水平为10.52%时,试验鱼皮肤中类胡萝卜素含量显著高于其它试验组（P〈0.05）,体表红质的a＊值最高;试验鱼肝胰脏中超氧化物歧化酶、过氧化氢酶的活力随脂肪水平的升高而下降,饲料脂肪水平对碱性磷酸酶、乳酸脱氢酶等免疫指标没有产生显著影响（P〉0.05）。上述研究说明,在配合饲料中添加一定量的螺旋藻时,锦鲤着色效果最好时的适宜饲料脂肪水平为10.52%,提高饲料脂肪水平不会持续提高锦鲤对螺旋藻的利用效率。

| Abstract: | A feeding trial with triplication was conducted to investigate the effects of dietary lipid levels on body pigmentation and immune indicators in koi carp Cyprinus carpio.The koi carp with initial body weight of（5.85±0.19） g were fed five diets containing 12% Spirulina and different lipid levels（5.36%,7.74%,10.52%,12.85%,and 15.45%） to apparent satiation at 15-25 ℃ for 60 days.The results showed that there was significantly higher concentration of carotenoid in the skin of the fish fed the diet containing 10.52% lipid（with the maximal value） than that in the fish fed the other experimental diets（P0.05）.The superoxide dismutase（SOD） and catalase（CAT） activities were found to be decreased with the increase in dietary lipid levels.No significant differences in alkaline phosphatase（AKP）,and lactate dehydrogenase（LDH） activities were observed in the fish fed different diets（P0.05）.It was concluded that the diet containing 10.52% lipid level showed improvement of body color in the koi carp fed the diet containing equivalent Spirulina. |
