Serum metabolomic analysis between treatment groups. CON, control group; S, the group infected with Salmonella Enteritidis; P, the group infected with Salmonella Enteritidis + 100 mg/kg Puerarin at day 17. A Differential metabolites between the S and con groups shown in the form of volcanic plots. Differential metabolites between the S and P groups shown in the form of volcanic plots. B Principal component analysis (PCA) score plot for the three groups in both positive and negative ionization modes. C OPLS-DA score plot of metabolite profiling between the S and con groups in ESI + and ESI-; OPLS-DA score plot of metabolite profiling between the S and P groups in ESI + and ESI-
