Squared correlation (r²) between direct genomic breeding values (DGV) and the corresponding de-regressed EBV for validation bulls using different SNP sets. a Calving performance traits are daughter calving ability (DCA); maternal calving ease at first calving (heifer; CEh); maternal calf survival at first calving (heifer; CSh) and maternal calf survival at later calvings (cow; CSc). b Body conformation traits are conformation score (CONF); rump (RU); mammary system (MS); feet & legs (FL); dairy strength (DS); rump angle (RAN); pin setting (PS); pin width (PW); loin strength (LS); udder depth (UD); udder texture (UT); median suspensory ligament (MSL); fore udder attachment (FA); front teat placement (FTP); teat length (TL); foot angle (FAN); heel depth (HD); bone quality (BQ); leg side view (LSV); set of rear legs (SRL); leg rear view (LRV); stature (ST); height at front end (FE); chest width (CW); body depth (BD) and angularity (ANG). Set 1 (38,405 SNPs) = set of SNPs from the 50K SNP panel; set 2 (601,717 SNPs) = set of SNPs from the HD SNP panel; set 3 (1206 SNPs) = set of significant (genome-wise false discovery rate of 5%) SNPs for calving and body conformation traits; set 4 (39,564 SNPs) = set of combined SNPs from sets 1 and 3; set 5 (39,408 SNPs) = set of combined SNPs from set 1 and a set of significant SNPs for all traits within or nearby genes (± 100 kbp around the gene); reliability = average reliabilities of the EBV from the December 2014 genetic evaluation for validation population
