中国对虾不同生长阶段对蛋白质、脂肪、糖类和无机盐的需求

On Needs of Penaeus orientalis in Protein, Fat,Glucose and Inorganic Salt at Different Growing Stage

设计不同蛋白质、脂肪、无机盐、糖类配比的9个配方饵料，对中国对虾前、中、后3个生长阶段进行了饲喂试验。结果：各营养要素影响对虾增重的顺序第一阶段为脂肪＞蛋白质＞无机盐＞糖类，最适量为7％、40％、13％、20％；第二阶段为蛋白质＞脂肪＞糖类＞无机盐，最适量为45％、5％、23％、13％；第三阶段为蛋白质＞脂肪＞糖类＞无机盐，最适量为45％、5％、23％、11％。影响饵料效率的顺序为第一、二阶段脂肪＞蛋白质＞无机盐＞糖类，第三阶段蛋白质＞脂肪＞无机盐＞糖类。

An experiment was conducted on feeding with diets, which were made according to nine feed formulas designed in different content ratio of protein, fat, glucose and inorganic salt,at former, middle and taler growing stage of Penaeus orientalis. The experimental results showed:each nutrient factor influenced on the increase of the prawn body weight at the first growing stage in such sequence as fat > protein > inorganic salt > glucose with the optimum content of 7 %, 40 %,13 % and 20 % separately; at the second stage, protein> fat> glucose> inorganic salt with the optimum content of 45 %, 5 %, 23 % and 13 % separately; at the third stage, protein > fat > glucose > inorganic salt with the optimum content of 45 %, 5 %, 23 %, 11 % separately. The influence on the feed efficiency in order was: at the first and second growing stage, fat > protein > inorganic salt > glucose; at the third growing stage, protein> fat > inorganic salt > glucose.
