Table 2.

Alpha-diversity in the duodenum, jejunum, and ileum.

duodenum jejunum ileum
Chao1 724.81 ± 51.99 646.38 ± 47.52 719.28 ± 49.89
Observed species 655.08 ± 46.51 558.12 ± 37.38 551.12 ± 41.90
Shannon's index 7.02a ± 0.14 7.04a ± 0.13 4.93b ± 0.25
Simpson's index 0.97a ± 0.00 0.97a ± 0.01 0.82b ± 0.02

Note: different superscript letters indicate that the alpha-diversity indices differ among the duodenum, jejunum, and ileum at P < 0.05. (n = 20–24).
