摘要
本文对中华鳖（TrionyxsinensisWiegmann）一龄鳖（体重100．0—125．sg）、二龄鳖（体重220．0—263.09）和三龄鳖（体重450.0—480.0g）的肌肉与背甲中矿物元素的组成进行了分析，结果表明：中华鳖体内含有22种以上的矿物元素，具有重要生理功能的硒、锌和铁等微量元素含量丰富，在肌肉中含量分别为（单位：mg／100g）：0．54、332、367；在背甲中含量分别为（单位：mg／100g）：1．50、8.12、8.8。本研究在分析与比较的基础上评价了中华鳖的营养价值，为中华鳖配合饲料的开发提供了理论上的依据。
Analyses of the composition of mineral elements in carcepace and muscle were carried out in one-year old (weight: 100-125g), two-year old (weight: 220-225g) and three-year old (weight: 450-480g)Chinese soft-shelled turtles (Trionyx sinensis). In muscle and carcepace of turtle there are more than 22 kinds of mineral elementS.There are rich trace mineral elements of important physiological functions,such as selenium, zinc and iron. The content of selenium. zinc and iron in the muscle of the turtle is 0.539, 3.32 and 26.7 respectively and in carcepace 1.495. 8.12 and 8.8 respectively. (unit: milligram per 100 gram sample). On the basis of analysis and comparison, the nutrition value and special medical value of the Chinese soft-shelled turtle are confirmed and the theoretical grounds to develop coordinating diet of the Chinese soft-shelled turtle are provided in this paper.
