摘要
在基础饲料中分别添加5种不同含量的螺旋藻(0%、4%、8%、12%、16%)饲养锦鲤60 d,研究其对锦鲤生长和养分消化率的影响。实验结果显示,随着螺旋藻添加量的不断增加,实验组锦鲤的增重率、肝体比指数有显著增加(P<0.05),但对特定生长率、肥满度、内脏比等影响不显著(P>0.05)。随着螺旋藻添加含量的增加,实验组的干物质消化率、蛋白质消化率、脂肪消化率也逐渐升高,均显著高于对照组(P<0.05)。
spirulina levels diets（0%,4%,8%,12%,16%） were designed feeding 60 days to study the effects of spirulina on growth and nutrient digestibility of ornmmental carp.The results showed that with spirulina dosage increased,the body weight gain and HSI were significantly increased（P〈0.05）.There were no significant differences（P〉0.05） in SGR,CF and VSI between experimental and contral groups.As spirulina increasing,nutrient digestibility,lipid digestibility and protein digestibility were significantly higher than that of control group（P〈0.05）.
