The traits inferred were total number of sperm, motility, volume, and density. Traits were recorded from 2012 to 2021 using a CASA system (computer aided sperm analysis) and provided data from 96,815 ejaculates from 1647 Pietrain boars. The animals were kept in three Austrian artificial insemination (AI) stations. Genomic data were analysed using Illumina 60 and 80\u2009k SNP arrays and yielded 43,430 markers from 909 individuals after quality control. Genome\u2010wide association was based on a mixed linear association model with phenotypic pre\u2010correction. GWAS revealed three possible associations for total number of sperm on chromosome 8, 16, and 17, including two genes from the cadherin family (PCDH15, CDH12). Genetic parameters and breeding values were estimated using a single\u2010step GBLUP (ssGBLUP) procedure for total number of sperm and motility. Estimated heritabilities for total number of sperm and motility were 25.9% and 11.5%, respectively. Genetic correlation was \u22120.321 between motility and sperm density, and 0.419 between motility and ejaculate volume. Breeding value estimation provided proof of the advantage of ssGBLUP compared to pedigree\u2010based BLUP in this study, as reliabilities (\n                    <jats:italic>r<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    ) were significantly higher for young boars without phenotypes (0.346 vs. 0.196 for total number of sperm and 0.276 vs. 0.190 for motility). This indicates positive response to selection if included in routine genetic evaluation.\n                  <\/jats:p>","DOI":"10.1111\/jbg.70010","type":"journal-article","created":{"date-parts":[[2025,8,16]],"date-time":"2025-08-16T08:14:16Z","timestamp":1755332056000},"page":"193-202","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Genome\u2010Wide Association Study and Genomic Prediction of Sperm Quality Traits in Pietrain Pigs"],"prefix":"10.1111","volume":"143","author":[{"given":"Bauer","family":"Martin","sequence":"first","affiliation":[{"name":"Institute of Livestock Sciences, Department Agricultural Sciences BOKU University  Vienna Austria"},{"name":"PIG Austria GmbH  Steinhaus\/Wels Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1517-5829","authenticated-orcid":false,"given":"S\u00f6lkner","family":"Johann","sequence":"additional","affiliation":[{"name":"Institute of Livestock Sciences, Department Agricultural Sciences BOKU University  Vienna Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4348-6533","authenticated-orcid":false,"given":"Kahsa Tadel","family":"Gebre","sequence":"additional","affiliation":[{"name":"Institute of Livestock Sciences, Department Agricultural Sciences BOKU University  Vienna Austria"},{"name":"Department of Animal, Rangeland and Wildlife Sciences, Enda\u2010Eyesus Campus Mekelle University  Mekelle Ethiopia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9158-5563","authenticated-orcid":false,"given":"Pfeiffer","family":"Christina","sequence":"additional","affiliation":[{"name":"Centre for Animal Nutrition and Welfare University of Veterinary Medicine  Vienna Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,8,16]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijms21051572"},{"key":"e_1_2_10_3_1","unstructured":"Bates D.
