Fig 3. Enterotypes identified in fecal samples from piglets.

Four enterotypes named E1 to E4 (A) were identified among the samples collected from suckling 26-day-old (n = 222) and weaned 35-day-old piglets (n = 254) in 16 commercial farms. The 192 pigs with data available at both time points were used to show the proportion of pigs switching from one enterotype to another between d26 and d35 (B). The variability between farms is illustrated by the distribution of enterotypes at d26 and d35 in each farm (C).
