The present study was carried out to provide insight into the body composition of snakes, which is an important basis for determination of nutrient requirement and physiological processes. Carcasses of 86 captive snakes (31 pythons, 32 colubrids and 23 boas) were available for analysis. Skins and vertebrae bones of 11 snakes and livers of 64 snakes were analysed separately from the carcasses. Crude nutrients, major minerals and trace elements were investigated. The content of crude nutrients of the whole body was similar to those of mammals and birds. Relatively high contents of copper, zinc and especially of iron (up to 23,973 mg/kg dry matter) were found in the body, particularly in the liver. There was an increase of the iron content of the whole body over age.
本研究旨在深入了解蛇类的身体组成，这是确定营养需求和生理过程的重要基础。共有 86 条圈养蛇（31 条巨蟒、32 条游蛇和 23 条蚺蛇）可供分析。从这些蛇的尸体中分别分析了 11 条蛇的皮和脊椎骨，以及 64 条蛇的肝脏。研究了粗营养素、主要矿物质和微量元素。全身的粗营养素含量与哺乳动物和鸟类相似。体内（尤其是肝脏）铜、锌和铁的含量特别高（高达 23973 毫克/千克干物质）。随着年龄的增长，全身铁含量也在增加。
