Abstract

The aim of this study is to determine the influence of EM stimulations on macro and micro element concentrations
in the blood, to determine if changes in ion concentrations depends on their basal values and to determine the
usefulness of this kind of stimulation in the maintenance of the blood macro and micro element levels in cows. 17 cows
were included in the experimental group (affected by a unique EM stimulation protocol of three weeks duration) and
9 cows were included in the control group. Significantly higher (P <0.01) concentrations of Ca, P, Na and Cu and lower
(P <0.05) concentrations of Zn were found in the experimental group after EM stimulation. Dynamic changes of macro
and micro element concentrations were inversely proportional to their basal value before the beginning of the
experiment which means that animals with lower basal concentrations had greater changes of value during stimulation.
Dynamic changes of Ca, P, Mg, Fe, K and Cu were more notable in the experimental group that was exposed to EM
stimulation compared to the control group. However, dynamic changes of Na and Zn concentrations were identical in
the experimental and control groups. Exposure of cows to EM stimulation had a positive effect at Ca and P
concentrations and improved calcaemia and phosphatemia in all the exposed animals.
