Fig. 2From: Early inoculation with caecal fermentation broth alters small intestine morphology, gene expression of tight junction proteins in the ileum, and the caecal metabolomic profiling of broilersEffect of early inoculation on villus height and crypt depth of the small intestines of 14-day-old and 28-day-old broilers. a Villus height of the duodenum, jejunum and ileum. b Crypt depth of the duodenum, jejunum and ileum. c Ratio of villus height to crypt depth (V/C) of the duodenum, jejunum and ileum. The data are presented as means ± SEM (n = 8). Asterisks (* and **) represent significant differences with P < 0.05 and P < 0.01, respectively.
