The aim of this study was to evaluate the effect of feeding selenium-enriched Enterococcus faecium on Se concentrations in muscles and on meat quality indicators in finishing pigs. Pigs were fed Se-enriched E. faecium (n = 12), sodium selenite (n = 12) and Se-enriched yeast (n = 12). The tested feed mixtures were fed for a period of 3 months before the pigs were slaughtered. The Se concentrations in muscles achieved by the use of Se-enriched E. faecium were comparable to those achieved in sodium selenite diets and lower (p less than 0.05) when feeding Se-enriched yeast. Concentration of Se in serum and glutathione peroxidase (GSH-Px) activities did not differ in animals fed different Se forms. No differences in indices of meat quality were found among the groups. Se-enriched E. faecium bacteria can be recommended as an alternative Se source for finisher pigs with the similar efficacy as sodium selenite.
