    Establishment of baseline values of copper, zinc and manganese in ostriches in Zimbabwe: a preliminary study.
    (Zimbabwe Vet Journal, 2000) Siwela, Andrew H.; Shonhai, A.; Foggin, C.M.; Revol, B.
    Ostrich (Struthio came/us) sera from apparently 302 healthy birds on 32 different fanns 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 detennined according to age groups i.e chicks, growers and b~eeders. 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.
