AbstractThis study used two groups of adult and healthy birds, joined the first group of 15 pigeons laughing doves
granivores , five of them for the purpose of anatomical study, and another ten for the purpose of histological study,
and included a second group of 15 birds Kingfisher white breasted carnivores, and five of them for the purpose of
anatomical study, and ten of them for the purpose of histological study.
The Anatomical study included the study ofthe form ofduodenum position and shape in the laughing dove and
white breasted kingfisher birds, the histological study included histological structure of duodenum and measuring
the thickness of the wall consisting ofduodenum.
The study have showed that the duodenum in both the birds is a single surround the pancreas and the results
showed that the villi which were longer and thicken and contain more branches in its base part in kingfisher
copared with that of laughing dove bird which was shorter and thinner, It has been noted that there was differences
in layer thickness that form intestine wall .The mucosa layer was thinner compared with other layer.
It has been concluded that the difference of food type that the birds have can have clear effect in both
morphological and histological structure of duodenum ; namely ,the thickness of layers that forms their walls.
