Morphological comparative study of duodenum and jejunum between bronze fallow cockatiel and white eared bulbul

The current result aimed to investigate the comparative morphological note of duodenum and jejunum between two bird (white eared bulbul and bronze fallow cockatiel) according to their food type. In this study used (10 sample) from each bird. The small intestine was started from the pyloric opening and divided into three part (duodenum, jejunum, ileum) that located at the caudal part of abdominal cavity, there is no demarcation line between the three part and absent of Michal’s diverticulum in both bird. The duodenum in bulbul was appear light yellow in color that take incomplete u shape and recognized by its largest diameter that holding the pancreas. While in cockatiel smallest in diameter and take red appearance with u shape. The jejunum of white eared bulbul appear brown in color the take single lope in shape and it’s the longest part of small intestine, in cockatiel the jejunum has pink in color and the shape was parallel to u shape that absent of demarcation line with ileum.
