Genomic estimated breeding values and traditional estimated breeding values were compared regarding to selection differences. Data from altogether 9745 genotyped Norsvin Landrace boars and Norsvin Landsvin sows were included in the genomic relationship matrix and combined with the pedigree relationship matrix using a single-step procedure.  The GEBV’s increases the selection difference for litter size and maternal ability traits between 26% and 67% compared to traditional EBV’s.  Correspondingly, for the production traits the selection differences increased between 8% and 34% using the GEBV. In January 2014 genomic selection was fully implemented within the breeding program for Norsvin Landrace and for Norsvin Duroc.
