Abstract: The study was conducted to investigate the ultrastructure of proventriculus of the 7 days and 112 days old kadaknath fowl. The Scanning electron microscopic studies revealed that proventriculus was composed of tunica mucosa, tunica submucosa, tunica muscularis, and thin tunica serosa. The Mucosal folds formed concentric ring around the mucosal papillae at the proventricular glandular opening. Mucosal folds were composed of finger like tall columnar epithelium embedded on the mucosal folds. Proventricular glands were divided into several varying sized lobules with a central excretory cavity. TEM of proventriculus showed that the tall columnar epithelium of the mucosal fold, with numerous rough endoplasmic reticulum, mitochondria and basally positioned large round to oval nucleus, mostly oval. Numerous secretory granules of varying size were present at the supranuclear portion of the cell. the numbers of the secretory granules were more in the 112 days old bird compare to the 7 days old bird. Submucosal glands of proventriculus were composed of low columnar to cuboidal epithelium having large pear shaped basally positioned nucleus and numerous mitochondria and rER. The endocrine cells appeared in close contact with the basal lamina among the mucous and oxynticopeptic cells and they were more abundant deep in the tubular glands and crypts with numerous secretory granules of varying sized darkly stained at supranuclear portion.
