Zinc plays an important role in pig reproduction and is associated with boar sperm quality or quantity parameters. The aim of this study was to evaluate a relation between boar sperm quality parameters and seminal plasma zinc concentration. Thirty-eight ejaculates from thirty-eight boars from one AI centre were used in this study. The following semen quality and quantity parameters were evaluated: morphologically abnormal spermatozoa (MAS), sperm motility, semen volume, sperm concentration and total number of spermatozoa per ejaculate. Only non-significant differences were found among the groups in the MAS incidence and in the boar sperm motility parameter. The highest MAS incidence (24.3 %) was found in group with the lowest seminal plasma zinc concentration while the lowest MAS incidence (16.8 %) was noted in group with the highest seminal plasma zinc concentration. On the basis of these results we cannot conclude that there is a significant relation between boar seminal plasma zinc concentration and evaluated sperm quality parameters.
