Abstract :
Introduction: Esophagus for foodstuffs transfer, Crop for food storage are important organs in avian digestive system. Ducks habitat is more in water and they have many varieties species. There is no anatomical and histological research performed on esophagus and crop in muscovy duck, so this research was done. Material and methods: For this research 20 male and female muscovy duck)for anatomical study) were selected and esophagus and crop were studied anatomically. Then histological study on esophagus and crop was done with haematoxylin and eosin staining. Results: Anatomical results showed cervical esophagus was longer than thorasis esophagus. Crop was small and spindle shape. There are also longitudinal chains in lumen. Esophagus and the crop in male are larger than female. Histological results showed epithelium of the esophagus is stratified squamous. The lamina propria was thick and has many mucous glands. In Below of mucosal glands observed of A thick layer of lamina muscularis. It was consisted of smooth muscle. Epithelium of crop was stratified squamous keratinized epithelium. Conclusion: The esophagus and crop were similar in two sexes, and there is no significant anatomical and histological differences between the sexes. The average length and width of esophagus and crop in males are larger than females. This difference is significant in crop length.
