Prediction accuracies and expected predicted responses to selection on growth traits. a Prediction accuracy of genomic breeding values (GEBV) of growth traits (ADG1, ADG2, ADG3 and ADG4) when including exclusively each ADG trait (direct), exclusively 32 microbiome traits that were found informative for each of the ADG traits (Microbiome) or both (Combined). We used two strategies to select the 32 microbiome traits: the most informative alr-MG among all those that presented a non-zero genomic correlation with the ADG traits (Non-uniform rg subset) or the same criterion but including the restriction their genomic correlation with all ADG traits had a uniform sign (Uniform rg subset). b Prediction of the selection response expected for each ADG trait when selecting the 10% best animals (i.e., animals with the largest EBV for ADG1, ADG2, ADG3 or ADG4) under each strategy
