Abstract

The objectives of the study were to investigate the histology and ultrastructure of the caecum
and colon and histochemistry of the colon have been conducted on 50 Blanc de Bouscat male rabbits
with ages varied between 0- 30 days. The investigation showed that the mucosa of the caecum and colon
was composed of crypts with villar shape at 0-day of age and the length of the crypts decreased with
advancing age. The crypts were lined by striated epithelial cells. Goblet cells were prominent. The
absorptive columnar cells had apical microvilli and contained vacuoles of different size, ovoid to
elongated nucleus, mitochondria, rough endoplasmic reticulum and lateral membranous interdigitations.
Cells with polymorphic secretory granules were noticed. Varying degrees of positive reaction to PAS
diastase resistant material and diastase- digested material (glycogen) was found in the colon.
