Effect of Lp. plantarum FRT4 on gut microbiome composition. A Microorganisms with the top 15 relative abundances at phylum level. B Microorganisms with the top 15 relative abundances at genus level. CT: control group, hens fed with normal diet. HELP: model group, hens fed with high-energy low-protein diet. FRT4L, FRT4M, and FRT4H: experimental groups, hens fed with high-energy low-protein diet with 10⁹ CFU/kg, 10¹⁰ CFU/kg, and 10¹¹ CFU/kg Lp. plantarum FRT4, respectively
