Abstract

Histomorphological study was conducted on the oesophageal tonsils in six broiler Vigova Super-M ducks of six to eight weeks age. The location of the tonsil was at the junction between oesophagus and proventriculus. In histological sections six to eight isolated tonsillar units were seen in the lamina propria near the base of the oesophageal folds. Each tonsillar unit consisted of a crypt lined by lymphoepithelium and surrounded by dense lymphoid tissue. The tonsillar units were seen encapsulated by connective tissue and composed of many large lymphoid nodules separated by internodular areas. The secretory portion of the mucosal glands of the oesophagus were firmly associated with the lymphoid tissue and the cylindrical epithelium was transformed to lymphoepithelium. The oesophageal tonsils offered immunological protection at the entrance of stomach. Keywords: Oesophageal tonsils, Histomorphology, Ducks
