1、分析检测,.35,No.18,2014贵州人工养殖子二代大鲵骨骼、肌肉中10种元素的测定熊铧龙,姚俊杰,蒋左玉,冯亚楠,朱俊华(贵州1大学动物科学学院水产科学系,贵州贵阳550025)摘要:为更好地了解人工养殖子二代大鲵的营养价值,采用常规营养方法测定了贵州人工养殖子二代大鲵骨骼和肌肉中的Ca、P、K、Na、Mg、Fe、Mn、Cu、Zn和Se十种矿质元素。结果显示:在骨骼中,10种元素的含量顺序为:P>Mg>Ca>K>Na>Zn>Fe>Mn>Cu>Se,CAP含量最高,se含量最低,分别为2976.13mg/100g和0.05mg/100g,钙磷比为1:6.98。四肢肌、背
2、肌和尾肌中Ca、P和Cu的含量均显著差异(P<0.05),且三个部位都以P元素的含量最高,分别为433.08、482.72、380.20mg/lOOg。五种常量元素以背肌最丰富,总量为742.08mg/100g,五种微量元素以尾肌最丰富,总量为7.95mg/100g。研究表明:相对于其他食物,贵州人工养殖子二代大鲵是一种高磷低钙的食物。因此,在进行大鲵养殖时,除选择适宜的水源外,应投喂一些含磷低的饵料,同时注意饵料种类的合理搭配。关键词:子二代,大鲵,骨骼,肌肉,元素AnalysisontenkindsofelementsinthebonesandmusclesofF2ge
