Total of 182 ejaculates were investigated in regard to the effect of season, breed and age on the quality of boar sperm. The boars of Yorkshire, Landrace, Duroc, Hempshire and Pietrain pure breeds and F1-crossbred pigs were divided according to age in four groups: 12, 13-18, 19-24 and 25 months. Ejaculates were examined in the following seasons: January-March, April-June, July-September, and October-December. Differences in ejaculate volume, total number, concentration and progressive motility (PM), as well as number of ejaculates with less than 65% PM, were estimated within seasons, breeds and age of boars. These results suggest that quality of every single ejaculate must be evaluated before using for AI.
