The effect of high levels of inorganic selenium (NaiSeOs) was investigated on activity GSH-Px in blood plasma of chickens. For experiment, 140 chickens were used which were divided in 7 groups. The experiment lasted 42 days. The chickens of I group were not fed supplemental selenium. The chickens of II III, IV, V, VI and VII group were fed 2, 5, 10, 15, 20 and 30mg Se/kg of diet in form of Na2SO3. For determination of activity of GSH-Px spectrografic method was used. The highest activity of GSH-Px was found at the beginning of the experiment in all examined chickens (the eleventh day). The chickens of II, III, IV and V group had significantly higher activity and chickens of VI and VII group had lower activity then I group.
