Microbial genera and the functions of the gut microbiota in chickens in the long-term antibiotic treatment trial. A Dot plots showing the differentially abundant genera, determined by LEfSe, between the seven sampling time points for each group (P < 0.05, LDA score > 2). B Heat maps of microbial metabolic pathways at 4 dph, 25 dph, and 11 dpi. C Numbers of significantly different microbial metabolic pathways, determined by DESeq2 package, in each group between the seven time points (adjusted P < 0.05, FoldChange > 2). SigPath Num means the number of pathways with significant difference
