Gross and histomorphological observation of stomach of greater adjutant stork (Leptoptilos dubius)

Abstract

The present research was undertaken to study the gross and histomorphological observation of Stomach of Greater Adjutant Stork (Leptoptilos dubius). In the present investigation, two numbers of Greater Adjutant Stork were utilized at sub adult stage. The results showed that stomach of Leptoptilos dubius was distinctly divided two parts i.e. proventriculus and ventriculus. The wall of the proventriculus was thick and inner side of the wall contains proventricular glands. The inner side of ventriculus was covered by tunica cuticula layer. A pouch like structure divides the gizzard into two equal halfs and it contains some hair like projection. Histologically, the tunica mucosa of proventriculus contained longitudinal branched folds and lined by simple columnar epithelium. Pear or conical shaped glands found in the Tunica Sub mucosa layer of proventriculus and these glands were surrounded by capsule. Numerous narrow and deep folds were found in the tunica mucosa layers of ventriculus and these folds were covered by a tunica cuticula layer. Simple tubular glands were found in lamina propria mucosae.
