The effect of FMT on the compositional patterns of jejunal microbiota of weanling piglets. A The heatmap illustrating the core microbiome composition of control weanling piglets. The core microbiome for each group was identified based on a sample prevalence of > 20% and at a relative abundance frequency of > 0.01% at the genus level. The X-axis represents the detection threshold, indicating the relative abundance percentages. The color gradient represents the prevalence of each genus across the samples, with the scale ranging from 0.0 (blue) to 1.0 (red). Higher prevalence is indicated by warmer colors (closer to red), while lower prevalence is shown by cooler colors (closer to blue). B Heatmap illustrating the core microbiome composition of control weanling piglets received FMT. C Linear discriminant analysis (LDA) effect size (LEfSe) chart displaying differentially abundant taxa between control and FMT groups. D Multiple regression analysis of bacterial genera associated with control and FMT piglets with representation of significance and covariate influence. E Correlation between the abundance of various bacterial genera in control and FMT groups and the genus Pseudoscardovia in the jejunum
