The Influence of Freezing on Some Rare Breeds Boar Semen Cryopreservation

摘要

Despite the new researches in boar semen cryopreservation, application of frozen-thawed (FT) semen in commercial artificial insemination (AI) programs is still limited. The main sources of semen used in AI are semen preserved on room temperature (RT) and sometimes fresh (F) semen. However, the use of male germplasm from genebank on some rare breeds is connected with the ability to use frozen semen. The aim of this study was to evaluate the effect of semen preservation method and especially the influence of freezing on Red Mangalitsa and Bazna boar semen cryopreservation.
