The Se supplements did not influence rabbit growth, feed intake and nutrient composition of meat. In rabbits receiving selenite, the Se concentration in the loin and hindleg meat increased by 23 and 19 %, respectively,. In rabbits fed Se-yeast and Se-algae, the Se content in meat doubled from 0.11 - 0.15 mg/kg to 0.24 - 0.29 mg/kg. In all supplemented groups, the activity of glutathione peroxidase in the loin meat was higher than in control rabbits by 51.9 - 72.8 % (P< 0.001). The oxidative stability of meat, however, was not influenced. In can be concluded that the enrichment of meat with Se was the main benefit of supranutritional Se supply in rabbits. Se-yeast and Se-algae were more effective in increasing Se content in meat than selenite.
