Effects of SalA on intestinal core microbial community characteristics of ZDF rats. A Intestinal microphyla classification in rats at the phylum level. A bar chart of the composition proportion of different groups of bacteria was drawn. The abscissa represents different groups. The ordinate represents the richness of bacteria, and different colors represent different types of bacteria. B Relative abundance of Bacteroidetes, Firmicutes, and Tenericutes; C intestinal microphyla classification in rats at the family level. A bar chart of the composition proportion of different groups of bacteria was drawn. The abscissa represents different groups, the ordinate represents the richness of bacteria, and different colors represent different types of bacteria. D The relative abundance of Dehalobacteriaceae, Desulfovibrionaceae, Lachnospiraceae, and Prevotellaceae. N = 10
