Aim: The present investigation was undertaken to establish anatomical norms on gross anatomical, histomorphological and histochemical parameters of infundibulum of Pati and Chara-Chemballi ducks. Materials and Methods: In the present investigation, 12 (twelve) each Pati and Chara-Chemballi ducks in their laying period (42 weeks age) were utilized. Results: The mean length, breadth, thickness and weight of infundibulum were significantly higher in Chara-Chemballi duck than Pati duck. Though most of the histological parameters are almost similar, but the mean height of lamina epithelialis mucosae was significantly higher in Chara-Chemballi duck (30.234±0.389 µm) than in Pati duck (23.906±0.332 µm). PAS reaction was moderate at apical part of lining epithelium in Chara-Chemballi duck whereas the same is weak in Pati duck. Conclusion: Result obtained showed that the Chara-Chemballi duck revealed significant difference in all the parameters as compared to Pati duck.
