The aim of the experiment was to determine the effect of selected antioxidants (selenium, copper, vitamins E and C) on the antioxidant status of breeding boar ejaculate and ejaculate quality. In the first control group of boars (n = 10), the amount of antioxidants was not increased in feed. The second experimental group (n = 10) received the addition of selenium (0.5 mg/kg of diet), copper (10 mg/kg of diet), vitamin C (350 mg/kg of diet) and vitamin E (70 mg/kg of diet) in feed. The experiment lasted for 90 days. The addition of antioxidants increased GPx (by 28%), selenium content (by 49%; P<0.05), SOD (by 9%; P<0.05) and level of copper (by 63%; P<0.05) in the experimental group of boars. In the control group, the decrease of sperm motility (by 22%; P<0.05) was found at the end of the experiment. Other measured parameters such as ABTS antioxidant capacity, levels of MDA, metallothionein, zinc, ejaculate volume, concentration, total count of sperm and percentage of abnormal sperm cells were not significantly affected. The above mentioned results show that the addition of antioxidants does not increase the ejaculate quality but their lack can damage the quality indicators of boar ejaculate.
