【摘要】 在循环水养殖模式下,为研究饲料中添加胆汁酸对欧洲鳗鲡生长及血清生化指标的影响,将9口养殖初始体重(140.00±0.22)g欧洲鳗鲡的精养池随机分为3个处理组,每个处理组3个重复,分别投喂基础饲料(对照组),以及胆汁酸添加水平为500mg/kg、和1000mg/kg的试验饲料。试验期为90 d。结果:饲料中添加胆汁酸可显著提高欧洲鳗鲡的增重率、特定生长率、饲料转化率和日摄食量(P<0.05);显著提高血清总胆汁酸和高密度脂蛋白胆固醇水平(P<0.05),降低血清总胆固醇、甘油三酯和低密度脂蛋白胆固醇水平(P<0.05),胆汁酸添加组间各项指标均无显著差异(P>0.05)。表明:饲料中添加胆汁酸可提高欧洲鳗鲡的生长性能,有益调节血脂水平。更多还原

【Abstract】 The present trial was conducted to investigate the effects of dietary bile acid supplementation on growth performance and biochemical indices of European eels(Anguilla anguilla). The eels cultured in nine intensive ponds with water recirculating system, average body weight being 140.00±0.22 g per fish, were randomly divided into three treatment groups with three replicates in each group. The dietary bile acid levels of the three treatment groups were 0(control group), 500 mg/kg, and 1000 mg/kg, respectively. The trial period was 90 days. The weight gain rate, specific growth rate, feed conversion rate and daily feed intake were significantly increased by bile acid supplementation(P<0.05). The levels of total bile acid and high density lipoprotein cholesterol were significantly increased by bile acid supplementation(P<0.05). The levels of total cholesterol, triglyceride and low density lipoprotein cholesterol were significantly decreased by bile acid supplementation(P<0.05). There were no significant differences of the growth performance and the serum biochemical indexes between those two bile acids groups(P>0.05). The above results indicated that dietary bile acid supplementation might effectively improve the growth performance and have beneficial effects on serum lipid indices. This study was supported by China Agriculture Research System(CARS-46).更多还原
