The aim of this study was to verify the effects of adding organic selenium to the diet of pigs (during different fattening periods) on their fattening capacity and carcass value. Hybrid pigs (n=72) were divided into 4 groups, 3 experimental (where Se was administered at different times of the fattening period) and one control group. Se (Sel-Plex) was added at a dose of 1 mg per 1 kg of complete feed mixture. After reaching the average live weight of 109.8 kg, the individuals were slaughtered and subjected to detailed dissection. Regarding the evaluation of selected fattening capacity characteristics, none of the groups showed any effect of the added Se. Similar results were obtained for quantitative characteristics of the carcass value. In assessing the qualitative indicators, the carcasses of experimental animals had better colour and higher water content than those of control pigs.
