P. copri identified as a hub bacterial species decreasing lean meat percentage (LMP) of pigs. a OTU-level network diagram for identifying co-abundance groups (CAGs) responding to porcine LMP. Node sizes show the average abundance of each OTU. Red and grey lines between nodes indicate the positive and negative correlations between the nodes, respectively. Only lines corresponding to the correlations with a magnitude greater than 0.5 are drawn. The OTUs passing quality control (relative abundance ≥ 0.1% and present in at least 1% of pigs in the test cohort) were grouped into 12 CAGs by permutational multivariate analysis of variance (PERMANOVA) when P < 0.005. The color gradients on the right show the P values and coefficients (in the brackets) of the correlations between CAGs and the LMP. b Key OTUs of fecal microbiota associated with pig LMP. The histogram shows the Z scores computed for the OTUs significantly associated with the LMP using a two-part model. Only those OTUs for which the Z scores were ranked in the top 20 for positive (red bars) and negative (blue bars) association are shown. c Bacterial species significantly associated with the LMP using metagenomic sequencing data. The histogram shows the LDA scores computed for bacterial species differentially abundant between the samples with extremely high (n = 8) and low LMP (n = 8)
