The objective of the present study was to evaluate the influence of two mineral preparations on the level of selected elements Ca,P,Mg,Na,K,Fe,Cu,Zn in the hide hair of cows kept on farm A in the south-eastern part of Poland. The animals under study were divided into three treatment groups, twenty cows in each. Group C received no mineral additives, Group D1 was fed rations supplemented with ammonium phosphate - POLIPASZ A (produced by a Chemical plant in Police), and Group D2 received in their rations the mineral-herbal mixture BOVIFOSFOMAG (formulated by the authors). The experiment showed that addition of minerals to cow rations resulted in significantly higher levels of Ca,Mg,Cu and Zn in the hide hair of cows that received BOVIFOSFOMAG supplement and of phosphorus in the group supplemeted with POLIPASZ A.
