半散放猎豹毛发微量元素含量比较

许多微量元素与动物生理生化机能有着密切的联系,对机体的生长发育和维持健康起着重要作用.近年来,微量元素研究日渐得到重视,如Cu、 Zn、 Mn、 Se、 Pb等微量元素参与酶、激素和维生素代谢,影响动物生殖功能(Suchocki et al., 2003).

Comparison of hair trace elements content in different age groups of semifree-ranging cheetah (Acinonyx jubarus)

Five trace elements,including Cu,Zn,Pb,Mn,Se,were determined in the hair of 50 individual cheetahs (Acinonyx jubarus). Cu, Zn were determined by flame atomic absorption spectrophotometry (FAAS); Mn, Pb were determined by graphite furnace atomic absorption spectrometry (GFAAS)while Se was determined by atomic absorption spectrometry (AAS). The corresponding amounts of trace elements are significantly different according to different genders. The Cu and Zn amounts in the hair of different age groups differ significantly. The zinc amount increases continuously from sub-adult group to adult group with a peak in the adult group and then a slight decrease in the senior group. The copper amount increases with age. Manganese and lead amounts of different age groups differ little,but tend to increase with age. The selenium amounts of different age groups differ significantly with the peak in the adult group.
