The approach will be to use high-density genotyping and deep sequencing of expressed genes in gilts with novel phenotypes and differences in estimated breeding values for age at puberty to develop genomic markers that will aide in identification of sows with improved fertility. Markers identified in the resource population will be validated in at least three industry populations and a panel of validated genomic markers will provided to the industry through extension activity so that they may be adopted and used in selection programs to improve lifetime productivity of sows and increase efficiency of pork production.
