abstract
The present study was carried out on twelve birds of local hill fowl of Uttarakhand divided into two age groups viz. 0 day and 6 months of age with six birds in each group. The birds were procured from the Instructional Poultry Farm (IPF), Nagla, GBPUA&T, Pantnagar, Uttarakhand. The scanning electron microscopic (SEM) studies showed numerous plical folds lined by the surface epithelium in the local hill fowl. Further, the lymphocytes and other cellular elements were found to be protruded from the cut surface of plica of the bursa of Fabricius. The follicular associated epithelium and interfollicular epithelium were also observed.
