ssGBLUP models = a single-step genomic BLUP (ssGBLUP) model, a featured ssGBLUP (ssFGBLUP) model, and weighted ssGBLUP models with a region size of 1 (ssWGBLUP_bin1), 30 (ssWGBLUP_bin30), or 100 SNPs (ssWGBLUP_bin100)
SNP sets = SNPs in the 54K-SNP chip (54K), SNPs in the 54K-SNP chip together with sequencing SNPs selected by Denmark–Finland–Sweden (54K + DFS), SNPs in the 54K-SNP chip together with sequencing SNPs selected by France (54K + FRA), and SNPs in the 54K-SNP chip together with both sets of selected sequencing SNPs (54K + DFS + FRA)
IFLh the interval from first to last insemination in heifers, IFLc the interval from first to last insemination in cows, ICF the interval from calving to first insemination
_a,b,csubscript letters to the left are for comparisons among models using the same SNP set, and superscript letters to the right are for comparisons among SNP sets using the same model. Regression coefficients with no common letter differ significantly (P < 0.05)
