. "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 78 boars divided into four equal groups. The individual groups received feed mixtures with the supplement of 0.3 and 0.6 mg Se/kg of feed mixture in organic form, and 0.3 and 0.6 mg Se/kg of feed mixture in inorganic form. In the last 30 days of our study the boars were exposed to higher ambient temperatures. 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 . The group of boars receiving the inorganic selenium supplement of 0.6 mg/kg of feed mixture had a lower sperm concentration however ejaculate volume increase occurred at the same time. In our experiment the groups of boars receiving the selenium supplement of 0.6 mg/kg of feed mixture in both organic and inorganic form had the most equal values of the total count of sperm produced. It can be assumed this rate of selenium is capable of eliminating the impacts of heat stress on breeding boars to a certain degree."@en . "Research in Pig Breeding" . "2" .
