The study was designed to investigate histomorphological and histochemical structures of the stomach in the partridge. Twelve healthy birds were collected,euthanized, their abdomens were dissected, and then their stomachs were identified, photographed in situ. Specimens were fixed as well and then processed for histological and histochemical staining techniques.
Gross findings indicated the presence of a stomach of two divisions that were (proventriculus) and (ventriculus). The proventriculus was elliptical in shape and separated from the second part by isthmus. The ventriculus appeared circular in shape . It was located at the left side of the thoracoabdominal cavity. The luminal surface of proventriculus showed longitudinal mucosal folds with the presence of papillae between the end of isthmus and beginning of ventriculus. Ventricular luminal surface was greenish to yellowish in color; it had rough folds in the center then arranged transversally in the end with presence of cuticle. Histologically the gastric wall was constructed by four tunicae (mucosa, submucosa, muscularis and serosa). The luminal surface of stomach was irregular due to presence of openings of superficial glands with the top of papillae. The epithelium was simple columnar invaginated to form superficial and deep glands lined in their basal parts by cuboidal cells. In ventriculus the surface covered by cuticle with absence of muscularis mucosa. Tunica muscularis was very thick composed from three layers in different directions to adapt the gastric functional contraction. Histochemically the epithelium and glandular ducts were reacted positively with PAS due to their neutral mucin composition.
