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,以P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/100g。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。Abstract ,Ten kinds of elements, including calcium, magnesium, phosphorus, sodium, potassium, iron, copper, manganese,zinc and selenium,in the bones and muscles of Andrias davidianus of GUI ZHOU were determined with routine methods to explore its nutritional characteristics. The results showed that.In the bones,the contents of ten kinds of elements were phosphorus 〉magnesium 〉calcium 〉potassium 〉sodium 〉zinc 〉iron 〉manganese 〉 copper〉selenium,and the highest content was phosphorus,the lowest was selenium,the phosphorus and selenium contents were 2976.13mg/100g and 0.05mg/100g,respectively. The ratio of calcium and phosphorus was 1：6.98. Calcium,phosphorus and copper had significant difference among the muscle of back,limbs and tail（p〈0.05）,and the phosphorus content in three parts were highest,and the content of phosphorus were 433.08mg/100g ,482.72mg/100g and 380.20mg/100g ,respectively. The total content of major elements （742.08mg/100g） in the muscle of back was highest,while the total content（7.95mg/100g） of trace elements in the muscle of tail was highest. The research showed that.compared with other foods,F2 generation of Andrias davidianus in Guizhou was a kind of high phosphorus and low calcium food. Therefore,we should choose appropriate water to feed Andrias davidianus,and pay attention to feed lower phosphorus bait and combine bait rationally.
