abstract
The present study was undertaken to explain the gross morphology and morphometry of bursa of Fabricius in Japanese quail. Bursa were collected from day-old to eight months of age of both the sexes. The bursa of Fabricius was located attached to the dorsal wall of the proctodeum and its shape and colour varied at different age groups. The maximum weight, length, width and number of plicae in the lumen of the bursa increased gradually and reached maximum at 5 weeks of age in both sexes.
