Description Bull fertility plays an important role in improving the economic value of the herd and is measured in terms of semen quality traits, which is influenced by both genetic and non-genetic factors. Polymorphism of MAP3K1/ CviQI (rs463712269), SPEF2/HpyCH4V (rs722354121) and PLCZ1/AvaII (rs208019489) and their association with scrotal circumference, sperm motility and plasma membrane integrity, respectively were studied on 239 bulls of different breeds reared in different frozen semen bull stations. The MAP3K1/CviQ1 assay revealed that T allele was more frequent in Ongole and Murrah population. RFLP at SPEF2/ HpyCH4V locus indicated fixation of T allele in both the exotic purebred cattle (Holstein Friesian and Jersey) whereas selective advantage of C allele was observed in Murrah buffaloes. Except in Holstein Friesian crossbred, other cattle genetic groups were with CC genotype for PLCZ1/AvaII assay and the Murrah population had low genetic diversity and heterozygosity excess. The PLCZ1/ AvaII genotypes had significant influence on the plasma membrane integrity of sperm in Holstein Friesian, Jersey and Ongole bulls. The plasma membrane integrity of sperm was reported to be high in heterozygotes (CG) of Jersey and Ongole cattle. The present study, concluded the importance of PLCZ1 gene as a marker for semen quality assessment and selection in bulls.
