Cryopreservation of boar semen is continually researched in reproductive technologies and genetic resource banking in breed conservation. For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of spermatozoa indicates active metabolism, membrane integrity and fertilizing capacity. Various researches have been trying to improve the quality of semen post-thawed in boar. Recently, polymorphism (g.158T>C) of phospholipase C zeta (PLCz) gene reported to be significant association with MOT. This study was conducted to evaluate the PLCz gene as a positional controlling for motility and kinematic characteristics of post-thawed boar semen. To results, The g.158 T>C SNP of PLCz was significantly associated with frozen semen motility and kinematic characteristics. g.158 T>C SNP was high significantly associated with MOT, VCL, VSL and VAP (p<0.0001, p=0.0002, p<0.0001 and p<0.0001, respectively). Therefore, we suggest that the intron region of the porcine PLCz, may be used as a molecular marker for Duroc boar post-thawed semen quality, although its functional effect was not defined yet. Whether the association is due to the candidate gene or not require further verification. Thus, it will be of interest to continue association studies in the regions surrounding those genes.
