The level of zinc and magnesium were determined in fleece of 85 ewes and their lambs of merino breed. The samples were collected 2—4 weeks after delivery. The measurements were carried out with the use of the AAS method after a wet mineralization of the examined material with a mixture of concentrated acids. The concentrations of the examined elements was on a relatively low level in wool of both ewes and lambs. The concentration of zinc ranged from 61.9 to 92.1 pg/g of fleece, while the content of magnesium ranged from 21.2 to 31.1 ug/g of fleece. Positive correlations were found for the relationship between concentrations of zinc and magnesium in wool of ewes and lambs. A statistical analysis of the relationship between concentrations of both bioelements in wool and in a whole blood of the animals was also carried out.
