Abstract

Ostrich (Struthio camelus) sera from apparently 302 healthy birds on 32 different farms around the country were analysed for three essential trace elements (copper, zinc and manganese) by atomic absorption spectrometry with the objective establishing baseline values which could be used as guidelines in the diagnosis of deficiency or toxicity of the trace elements in ostriches. Trace elements levels in ostrich sera were also determined according to age groups i.e chicks, growers and breeders. Comparisons were also done to determine whether the geographical regions had any influence on the levels of the trace elements in the different categories of birds. Results indicated significant variations with regard to age and geographical region variations in the level of copper. No significant age variations were evident for manganese levels but regional differences were noted. Zinc levels did not show significant geographical differences but variation in the concentration of the trace element according to age was strongly evident.

建立津巴布韦鸵鸟体内铜、锌和锰的基线值:初步研究。
采用原子吸收光谱法对来自全国32个不同农场的302只健康鸟类的鸵鸟(Struthio camelus)血清进行了三种必需微量元素(铜、锌和锰)的分析,目的是建立基线值,该基线值可作为诊断鸵鸟微量元素缺乏或毒性的指南。根据雏鸟、饲养者和饲养者三个年龄组测定了鸵鸟血清中微量元素的含量。还进行了比较,以确定地理区域是否对不同类别鸟类的微量元素水平有任何影响。结果表明,铜含量在年龄和地理区域差异方面存在显著差异。锰含量无明显的年龄差异,但存在区域差异。锌的含量没有明显的地理差异,但微量元素的浓度随年龄的变化非常明显。(津巴布韦兽医杂志,2000,31 (2&3):57-64)
