If considering livestock requirements, feed supplementation with this organic form of microelements, covered animals’ requirements in: Fe-27%, Cu-75%, Mn-30%. ZnO was the source of zinc. The experiments were carried out on 25 barrows. Digestibility of the main nutrients, the apparent absorption and balance for Fe, Cu, Mn as well as Zn, Ca, P, Mg, were carried out. The supplemented microelements did not have the adverse effect on digestibility of the main nutrients and the apparent absorption of Ca, P and Mg. Barrows fed with feed containing Y-Fe excreted more iron with urine than the control, which statistically significantly (P
