The relative abundance of fecal microbial communities of NC and BAO piglets. A Venn diagram. B Relative abundance at the phylum level. C Relative abundance at the genus level. D Heat map of differential bacteria at phylum level. E Heat map at KEGG pathway. F–H The relative abundance of Prevotella, Oscillospira and Alloprevotella at genus level. Dates are presented as means ± SEM (n = 6). ^*P < 0.05; ^**P < 0.01. NC, corn-soybean meal basal diets; BAO, corn-soybean meal basal diets + 5 kg/t benzoic acid + 500 g/t essential oils
