The content of Ca, P, Zn, Cu, Fe and Mn was assayed in wool samples obtained from 81 sheep from 13 breeds. Macro- and trace element concentrations were determined by atomic absorption spectrophotometry (Perkin Elmer-380). In merino type and local breeds there were no statistically significant differences in Ca content, whereas the half-merino breeds exhibited a low content for Tsigai sheep and Suffolk sheep. The content of P showed larger variations in the three groups as well as between the breeds. With regard to the trace element contents, there were significant differences between the different breeds within one production type. No substantial differences in macro- and trace element concentrations depending on the wool type were observed.
