Fig. 7

The species of significant differences at family level. The left picture shows the diversity of species abundance, each of which indicates the mean value of species with significant differences in the abundance between groups. The right picture shows the difference confidence between groups. The most left-hand point of each circle represents the lower limit of the 95% confidence interval of mean difference, and the most right end point of the circle represents the upper limit of mean difference and 95% confidence interval. The center of the circle represents the difference of the mean. The group represented by the circle color is a group with high mean value. The right end of the display results was the P-value of significance test for the corresponding species between groups. Piglets in CB treatment challenged with LPS (CB.C) and not challenged with LPS (CB.NC). Piglets in CON treatment challenged with LPS (CON.C) and not challenged with LPS (CON.NC)
