The present study was conducted on 24 Uttara fowl birds. The gross and ultra-structural features with their age-related changes in the large intestine were studied. The length and weight of caeca and colorectum and their diameter and thickness at proximal, middle and distal portions in all the age groups increased with advancing age. The left caeca were slightly longer and heavier than right caecum in all studied age groups. Scanning electron microscopy revealed that the proximal portion of caecum possessed finger like villi with dome shaped tip in day old bird which later showed tapering peak shaped tip. Villi were absent in distal portion of caecum and only folds were observed with wavy pattern bearing goblet pits. Villi in colorectum were tongue shaped with a curved tip and corrugated surface.
