From: Susceptibility of dairy cows to subacute ruminal acidosis is reflected in both prepartum and postpartum bacteria as well as odd- and branched-chain fatty acids in feces

Fig. 2

Principal-coordinate analysis (PCoA) based on Bray–Curtis dissimilarities in the composition of fecal bacterial communities at the amplicon sequence variant (ASV) level sampled on d 7 prepartum (a) and d 21 postpartum (b). Individual points in each plot represent the bacteria communities at the ASV level of an individual dairy cow and groups are indicated according to post-partum SARA susceptibility. Percentages shown along the axes represent the proportion of dissimilarities captured by PCoA in the two-dimensional (2D) coordinate space. P values of the permutational analysis of variance (PERMANOVA) model assessing differences in beta diversity > 0.1 are marked in the figure. Postpartum grouping: susceptible group (SU; n = 10): mean or median of time below pH 6 of at least 180 min/d; moderately susceptible group (MS; n = 7): 60 min/d < mean time of pH below 6 < 180 min/d and median time of pH below 6 < 180 min/d; moderately unsusceptible group (MU; n = 11): 10 min/d < mean time of pH below 6 < 60 min/d and median time of pH below 6 ≤ 30 min/d; unsusceptible group (UN; n = 10): median time pH below 6 = 0 min/d and mean time pH below 6 < 10 min/d. Due to early calving, the UN-group only contained nine animals in the prepartum period and MS (n = 3) and MU (n = 7) cows were merged into a single group (MO, n = 10)
