FIGURE 3.
16S rRNA gene analysis revealed a clear separation of the four groups investigated. Heatmap analyses of abundance genera in each group (A). Partial least squares discriminant analysis (PLS-DA) score plots based on the relative abundances of microbial genera of the first two components (B). Sows were regarded as the experimental units, n = 10 for each group. HG: day 109 of gestation of high litter performance sows; HL: day 21 of lactation of high litter performance sows. LG: day 109 of gestation of low litter performance sows; LL: day 21 of lactation of low litter performance sows.
