Anatomical, Morphometrical And Histological Study Of Large Intestine In Muscovy Duck (Cairina moschata)

Inroduction & Objective: Ducks have many varieties and often they lives in water. Large intestine isvital organ in bird's body for the functions in the physiology of digestion, water absorption, microbial and immunologic activities. There is no research performed on anatomical and hostological study on large intestine in adult muscovy duck. For this research 20 male and female muscovy duck were selected and large intestinewere studied anatomically. Then histological study on large intestine was done with haematoxylin and eosin staining. Histological results of large intestine in muscovy duck showed two sexes are similar and it is similar to other birds. Anatomical results showed the male Muscovy duck has a larger dimension in length and width than female andin the rectum length, this difference is significant. Anatomical features in muscovy duck showedcecum is a bar shaped and without branching. Rectum in muscovy duck was shorter than cecum and this organ was straight not curved.There was Ileal papilla in Muscovy duck. Histological features in muscovy duck showed there is cecal tonsil and lymphatic tissues was non follicular.The muscular layer
was large and thick. Conclussion:  The large intestine in the muscovy duck has differences and similarities with other birds. In
histological results there was similarity and in morphometrical results there was difference between the male
and female muscovy ducks.
