Table 2 Pearson’s correlations of (genomic) estimated breeding values (G)EBV based on full and reduced datasets (\(\rho_{f,r}\)), and slope (SE) of the regression of (G)EBV obtained from the full dataset on (G)EBV obtained from the reduced dataset (\(b_{f,r}\)) using univariate pedigree-based best linear unbiased prediction (PBLUP), univariate single-step genomic best linear unbiased prediction (ssGBLUP), the bivariate PBLUP, or bivariate ssGBLUP model

From: Genetic parameters and genomic prediction for feed intake recorded at the group and individual level in different production systems for growing pigs

  1. \(\rho_{f,r}\) and \(b_{f,r}\) were calculated separately based on all animals in the group-level dataset, the subset of genotyped animals in the group-level data set, and the subset of non-genotyped animals in the group-level dataset
  2. aUnivariate analyses were based on the group-level dataset only
  3. bBivariate analyses were based on the combination of group- and individual-level datasets
