Genomic parameters for boar semen quality traits were estimated. For estimation purposes, only animals with a “call rate” (proportion of identified SNPs out of all SNPs on the chip) > = 90 % were used. SNPs with Hardy- Weinberg equilibrium P-value > 0.0001 and minor allele frequency (MAF) > 0.05 were included for further analysis. The total number of genotyped animals was 903 and the number of SNPs was 48991 out of 50697. In terms of data, boars with at least seven defect-free collections between 2010 and 2022 were included in the estimation. A total of 30 400 collections from 599 boars were evaluated. The traits investigated were: semen volume (OB), sperm concentration (KO) and proportion of abnormal sperm (AB).
