Effect of single nucleotide polymorphism (SNP) in splicing site of the LPAR1 (lysophosphatidic acid receptor 1) gene on selected quality traits was investigated in frozen-thawed semen of Holstein-Friesian bulls. Splicing mutation A/G in the LPAR1 gene (rs43581860) was identified in 120 Holstein-Friesian bulls using PCR-RFLP technique (Hph I). Heterozygotes AG were the most frequent (37.5%) compared with AA (30.8%) and GG (31.7%) homozygotes. Observed differences in total motility (TM), sperm

For all three traits disadvantageous effect of heterozygotes AG was detected. This means that LPAR1 splicing mutation has significant effect on semen quality and should be considered as a new marker of semen quality in Holstein-Friesian bulls.
