Composition and metabolism of gut microbiota. (A) α diversity indices in faecal samples of adult PL, DL and DL + Lf pigs. (B) Bacteria composition at phylum and (C) genus levels (relative abundance) in faecal samples of adult PL, DL and DL + Lf pigs. (D) Discriminating genera in the faeces of adult PL, DL and DL + Lf pigs. (E) Two-dimensional PLS-DA score plot of integrated 1H-NMR spectra of adult PL, DL and DL + Lf faecal samples. Each dot represents an animal, projected onto first (horizontal axis) and second (vertical axis) PLS-DA variables. The ellipse determines the 95% confidence interval, which is drawn using Hotelling’s T2 statistic. PLS-DA model parameters: four latent variables included, R2Y (cum) = 90.4% (% of variance explained by the model), Q2 = 0.66 (predictive ability of the model) and p-value = 0.02. (F) Discriminating faecal metabolites between adult PL, DL and DL + Lf pigs. Formulas contained as lipids either: only plant lipids (PL, n = 6–9), a half-half mixture of plant and dairy lipids (DL, n = 7–8) or a half-half mixture of plant and dairy lipids supplemented with Lf (DL + Lf, n = 7–9).
