EFFECT OF SEASON AND BOARS BREED ON EJACULATE QUALITY

The effects of various seasons and boar breeds on ejaculate quality parameters were investigated on intensive swine production farms in the Autonomous Province of Vojvodina, Serbia. Significant value differences were noted in the ejaculate volume, the total sperm count and sperm concentration in ejaculates, and the number of poor ejaculates due to hot and cold seasons, as well as boar breed diversity. Therefore, the potential number of insemination doses per ejaculate varies seasonally, as well as according to different boar breeds. These facts should be taken into consideration when planning the intensity of boar reproductive exploitation.
