A Comparative Histomorphological and Histochemical Study of the Ventriculus between Iraqi Adult Geese (Anser anser) and Guinea fowls (Numidia meleagris)

The present study aimed to describe and compare the histomorphological histochemical structures ventriculus in Goose(Anser anser) Guinea fowls (Numidia meleagris). work was carried out on twenty apparently clinically healthy birds obtained from a supplier Baghdad city. They were allocated two equal groups of each type bird. utilized for histological investigations their organ. After anesthesia killing birds, abdominal cavity dissected, identified proper specimens its walls prepared. samples designated staining fixed solution bruin's fixative, while others general examination (10%) neutral buffered formalin. processing, sections stained with (2.5 PH) Alcian- PAS combination, periodic acid Schiff, Masson Trichrome, Hematoxylin Eosin stains. This elucidates that microscopic construct similar species. consists three tunicates (serosa, muscularis, mucosa), whereas submucosa is absent. wall showed some significant differences morphometric measurements. mucosa coated thick layer cuticles organized as wavy clear pink line parallel mucosal surface folds. simple cuboidal-columnar epithelium covered mucosa, which many proprial glands (simple tubular type) are lined by cuboidal epithelium, opens into crypts between A well-developed muscular comprised smooth muscle fibers layers inner circular outer longitudinal. Serosa composed loose connective tissue mesothelium. Mean thickness Cuticle, length folds, goose significantly higher than guinea fowl; these may be due variation diet. AB-PAS combined (2.5-PH) stains, cuticle layer, lining, gastric positive reaction Study normal structure Gizzard avian species, local male fowl meleagris) geese (Anser anser). Also Comparative histomorphological, histomorphometric measurements different species (Guinea geese). Keywords: Histomorphological, Histochemical, Ventriculus, fowls, Geese
