The experiment was based on feeding the organic and inorganic forms of selenium and the assessment of their effects on the laboratory values of the ejaculate (total count of sperm, sperm motility, ejaculate volume, sperm concentration and per cent of pathological sperm) in breeding boars. The experiment involved 18 boars breed Duroc divided into two equal groups. The individual groups received feed mixtures with the supplement of 0.3 Se/kg of feed mixture in organic form, and 0.3 Se/kg of feed mixture in inorganic form. The experiment lasted 20 weeks. The selenium supplement significantly decreased the sperm concentration in boars supplemented by 0.3 mg Se/kg of feed mixture in inorganic form; this group of boars also had a lower total count of sperm produced. Boars with an income of 0.3 mg Se/kg of feed mixture in an organic form had improved semen quality compared to inorganic forms.
