Aim of this thesis was to evaluate influence of inorganic selenium given, in a form of mineral supplement compound, to cows and their calves in order to supply their organism with selenium and also for the utilitarian traits. These were divided into two groups of six and supplemented with two different forms of selenium: group A was given inorganic sodium selenite, group B was given organic selenomethionine. Cows that were examined before the start of supplementation had average activity GPX in blood samples from group A 847,06 +- 170,77 ukat/l and group B 791,30 +- 91,20 ukat/l and concentration of Se of group A: 136,70 +- 27,97 ug/l and group B 95,77 +- 20,05 ug/l. It was found that cows postpartum had higher activity of GPx by 26% in group A and by 45% in group B. Difference between groups was statistically inconclusive (p < 0,28). Increase in concentration of selenium in blood of cows in group A was 7,5% and in group B 5%. In blood of newborn calves of both groups was not found conclusive difference of GPx (p < 0,43). Concentration of selenium in group calves A 160,18 +- 18,07 ug/l and group B 105,30 +- 24,26 ug/l. Difference in concentration of selenium in blood of cows and calves was statistically conclusive (p < 0,05), but because this difference was conclusive already before the supplement compound was given both inorganically and organically bound selenium, this result cannot be interpreted as conclusive influence of different forms of selenium supplemented. Weight and weight gain of calves were balanced between groups and statistically did not differ (p < 0,39). It can be concluded that both forms of selenium had analogical biological effect on focused parameters.In blood of newborn calves no conclusive difference in GPx was found
