Variance component estimates for carcass and meat quality traits obtained from each model. Models M1, M2, M3 and M4 include only host genotype information, only gut microbiome information, host genotype and gut microbiome information, and host genotype, gut microbiome and genotype-by-microbiome interaction, respectively, at three stages of production (Wean, Mid-test and Off-test) with different sets of markers and operational taxonomic units (OTU relative abundance) (FULL: contains all available markers and OTU, IR: contains informatively reduced markers and OTU, and RR: contains randomly reduced markers and OTU). Each individual bar in the plot depicts the total variance of each model, partitioned by the proportion of variance explained by host genomic effect (G), gut microbiome effect (\(M\)), host genomic by gut microbiome (\(G \times M\)) and pen (\(P\)) effects
