ABSTRACT

The objective of the study was to trace morphological changes in the wild boar semen in annual cycle. During 14 months 167 ejaculates were obtained from 3 boars. Smears were made of each ejaculate and evaluated. Classification of morphological changes of spermatozoa was based on Blom's scheme. Most defects of spermatozoa were found to vary seasonally. The proportion of normal spermatozoa in wild boar semen was the lowest in autumn, the main defect being spermatozoa with plasmatic droplets in proximal or distal position. However, in none of the months the proportion of defective spermatozoa exceeded 25%, which suggests that the observed morphological changes did not limit the fertility of the examined boars.

Key words: wild boar, spermatozoa morphology, reproductive season.
