This research was carried out to define the morphological features of Meckelיs diverticulum (MD) in duck and to investigate whether the MD resides in a constant position along the intestinal tract. For this purpose, a total of 30 adult healthy ducks of both sexes, 50-52 weeks of age were used. After dissecting,some morphological factors such as: total intestine length as well as the lengths of the intestine from the gizzard to MD (GMD), from gizzard to cloaca (GC) and from MD to the caecal opening (MDe) were measured. The weight, thickness and length ofMD were then recorded. By using t-test and analysing factors between two sexes we concluded that, the location of MD in total specimens was 91.52 ± 8.09 em far away from the gizzard. There was no significant difference between morphological factors of MD (weight. thickness and length) in both sexes (P>0.05). There was significant difference (P<0.05) between GMD. GC in both sexes. In histological studies ofMD, aggregated lymphatic follicles and thin muscularis mucosa were observed in tunica mucosa.
