The effect of BC + PC combination on the cecal microbiota structure in broiler chickens. A Genus-level phylogenetic tree, where the inner circle represents genus-level bacteria, and the outer circle indicates their relative abundances. B UPGMA clustering analysis represents the similarity of microbial community composition based on distance. C LEfSe analysis was conducted on the CON, BC, PC, and BC + PC groups, with an LDA (Linear Discriminant Analysis) score cutoff of > 4. Additionally, a t-test was employed to examine CON and BC + PC, further identifying differentially abundant taxa
