The structure of the different segments of small intestine was examined using scanning electron microscopy. Scanning electron microscopic study revealed variable shaped villi in each intestinal segment of Uttara fowl. By day 112 of age, the villi were tongue like in the duodenum, leaf like with domed tip in the jejunum and uniform, cylindrical shaped with rounded tip in the ileum. Post-hatch structural alterations like microvilli, secretory pores and different cells were seen in the ultrastructure of the small intestine of Uttara fowl. These structure having major role in digestion and absorptive functions of small intestine.
