Histomorphometric and Histochemical Finding of the Proventicular and Ventricular Stomach between the African Grey Parrot (Psittacus erithacus) and Black Francolin (francolinus) in South Iraq

Abstract

The study was done on sixteen specimens including: eight Parrot and eight francolins of both sexes.The current study aims to discover the structures of proventiculi and ventriculi belonging to these birdsspecifically their histologic and histochemical textures. The anatomical studies revealed that stomach of bothbirds consists of: proventiculi & ventriculi. Histological exam was showed that the wall of proventiculus ofthe Parrot and francolin composed of four layers including: mucosa, submucosa, muscularis and serosa. Theepithelia of proventiculi and venticulus were simple columnar cells for each bird.The obtained means of thickness of layers of proventiculus and venticulus appear different between maleand female of both birds.For histochemical studies there were some different reaction of PAS- stain which were detailed in the results.
