Incidence of pathological changes of spermatozoa depending on the age of boars

Popis výsledku v původním jazyce

The aim of this study was to assess the incidence of pathological changes of spermatozoa in breeding boars with special focus on character of changes during the activity of boars in insemination centre. A total of 1200 semen samples from 150 boars aged 9-36 months were analysed. The experiment was carried out from January to April 2017. Abnormalities of spermatozoa were assessed microscopically on stained native semen smears on glass slides. The percentage of spermatozoa with pathological defects differed among age categories. Total proportion of spermatozoa with morphological defects decreased with age. The highest proportion of spermatozoa with abnormal size and shape of head, proximal droplet and folded tail was recorded in younger boars (bellow 18 months of age). More frequent defects of acrosome were observed in the semen of boars older than 25 months. Also positive and negative correlations were found among individual groups of morphological abnormalities.
