The aim of the trial was to determine the efficacy of organic Se from Se-enriched yeast in placental transfer to piglets. In group I (n=8) the sows were fed during gestation and lactation a diet supplemented with inorganic Se (sodium selenite, 0.3 mg/kg of Se for the gestation and 0.38 mg/kg of Se for the lactation diet). In group II (n=8) the diet of the sows was supplemented with organic Se from Se-enriched yeast (0.3 mg/kg of Se for the gestation and 0.38 mg/kg of Se for the lactation diet). Se concentrations in the whole blood, colostrum and milk were higher (P less than 0.01) in the group of sows fed with the organic Se form. No differences in glutathione peroxidase activities in the whole blood were found between the two groups of sows. The concentrations of Se in piglet tissues were also higher when the organic form was provided. The use of the organic Se from Se-enriched yeast in sows resulted in greater transfer of Se to their progeny, however it did not have a positive effect on the antioxidant system of the organism.
