Caecal villi? A comparative histological and morphometric study of caecal and jejunal mucosa in adult rabbits.

ABSTRACT:

Background

Rabbits are herbivores with a distinctive digestive strategy that differs significantly from other caecal fermenters (e.g., horses, guinea pigs) and ruminants. In view of this, the current study aimed to highlight distinctive histological and morphometric features of the caecal mucosa in adult rabbits that accentuate its major role in digestion. The caecal and jejunal samples were harvested from five 1-year-old domestic rabbits and processed by regular paraffin-embedding histological technique followed by Goldner's trichrome staining. A comprehensive morphological and morphometrical analysis of the jejunal mucosa vs. caecal mucosa was performed.

Results

Microscopically, as in the case of the jejunal mucosa, the caecal mucosa presents long and often branched finger
