Score plot from PLS-DA (A–C) and OPLS-DA (D–F) of metabolite profiles of intestinal contents in piglets between each of the 2 groups from CON, LPS, and ZJ617 + LPS groups. CON, control piglets orally inoculated with PBS (▲); LPS, piglets following intraperitoneal injection (i.p.) with LPS (25 μg/kg body weight) (●); ZJ617 + LPS, piglets orally inoculated with ZJ617 (1 × 10¹⁰ CFU/d) for 2 weeks before i.p. injection of LPS (■). Each data point represents a function of the entire spectral profile of each subject (n = 6). OPLS-DA, orthogonal projections to latent structures-discriminant analysis; PLS-DA, partial least squares-discriminant analysis
