A study was carried out of 30, 160 ejaculate samples collected from 81 boars of the wbp (Polish Large White) breed and 182 boars of the pbz (Polish Landrace) breed. The ejaculate was collected manually with the sampling frequency of 4 - 5 days. An assessment of the ejaculate has been done with regard to the following physical properties: ejaculate volume, sperm cells concentration, percentage of sperm cells exhibiting proper motility, total number of sperm cells in the ejaculate and number of insemination doses obtained from one ejaculate. The collected data have been analyzed according to the season criterion with indication of the ejaculate collected in the individual months. It has been revealed that the most suitable ejaculate was collected from the domestic pig boars in November and December whereas in March, April and May the parameters lowered. The ejaculate collected in the springtime is characterized by a lower volume and a lower number of the motile sperm cells than in the other seasons. From the ejaculate collected in the autumn and winter period more insemination doses can be prepared than from those collected in spring and summer. No difference has been found between the boars of the wbp and pbz breeds with regard to their susceptibility to the seasonal factors’ influence.
