Lipopolysaccharide (LPS), lipopolysaccharide binding protein (LBP), and partial serum metabolites that differed in normalized abundance between fat and lean pigs, and their correlations with the LMP-associated bacterial species. a Comparison of the concentrations of serum LPS endotoxin and LBP between fat and lean pigs. High means the pigs with high LMP, and low represents the pigs with low LMP (fat pigs). b Metabolites that differed in normalized abundance between pigs with high (n = 8) and low LMP (n = 8). Red bars represent the normalized abundances of metabolites in lean pigs, blue bars show the normalized abundances of metabolites in fat pigs. c Correlations between the fatness-associated metabolites and the LMP-associated bacterial species. d Correlations between the high LMP-associated metabolites and the LMP-associated bacterial species. The color gradient represents the values of correlation coefficients
