Selection of additive log-ratio transformed microbial gene (alr-MG) abundances to be included in genomic evaluations. a Host-genomic correlations (rg) between average daily gains at different stages of the finishing period (ADG1, ADG2, ADG3 and ADG4) with (see the left side of the panel) 494 alr-MG with mean relative abundance of the numerator ≥ 0.001%, and a genomic correlation (rg) with any of the average daily gain traits (ADG1, ADG2, ADG3, ADG4) being different from 0 with a probability ≥ 0.85; or with (see the right of the panel) the 100 alr-MG with the additional restriction of having a uniform rg sign with all growth traits. b Change in adjusted R2 with an increasing number of alr-MG GEBV to 32 as explanatory variables using forward-wise linear regression to predict the GEBV of ADG1, ADG2, ADG3 and ADG4 for both alternatives defined in panel a. c Host-genomic correlations (rg) between average daily gains and the 32 alr-MG selected for both alternatives defined in panel a. d 36-traits genomic correlation matrix including the 32 alr-MG of the uniform (left) and non-uniform (right) rg subsets and average daily gain traits
