The purpose of this dissertation is the verification of antioxidants, the vitamin C, the vitamin E and selen influence on the spermgenesis of breeding boars. The ejaculate quality was evaluated with the use of qualitative and quantitative figures (the ejaculate volume, the motility, the sperm concentration and the number of abnormal sperms). The experiment was done at the boars' insemination station (ISK) in Velké Meziříčí. In the experimet, there were 12 boars of DUROC race involved. The boars were split into two groups. By the first boars experimental group (n=6) there were added into the feeding batch 350 mg of the vitamín C (ascorbe acid); 70 mg of the vitamín E (alfatocoferol) and 0,5 mg of selen (selenomethionin) per one kilogram of this special diet. The second group of boars was used as the checking group and the volume of the vitamin C, the vitamin E and the selen was not increased in their diet. The experiment was running for 90 days (June -- August). At the checking group the volume of their ejaculate was increasing untill the 60th day of the experiment, in the final stage it has significantly dropped, totally by -19%. By the experimental group, the volume of the ejaculate was constantly increasing trend and the total volume increase during the experiment duration was +32%. The sperm motility at the checking group has decreased from the original 69% down to 54%, while at the experimental group it has increased by approximatelly 1%. The sperm concentration check -- by the checking group it has increased by +6% and by the experimental group the sperm concentration has decreased by -24%. The number of abnormal sperms at the checking group has increased by +1% and by the experimental group the number of pathologic sperms has increased by +30%. Based on our results it is possible to say, that selen, the vitamin C and vitamin E do not have a provable effect on the boars ejaculate quality. But we must také into the consideration also the summer season, during which the experiment was provided. There were higher temperatures affecting the animals, which could have negative influence on the results.
