Pancreas is important due to exocrine and endocrine digestive secretions of mammals and poultry. In this regard, no comprehensive study has been conducted to special study for anatomical and histological comparison of this organ in both male and female ostriches. So, pancreas was studied anatomically and histologically in adult ostrich. For this study, 24 pancreases of adults ostriches were selected in slaughterhouses of Semnan province, Iran, and were studied anatomically. Then, tissue samples were obtained. The Samples were stained with Haematoxylin and Eosin Stain Kit. The histologic findings are largely similar to that of other poultry. In endocrine region of pancreas only 2 types of cells were recognizable; A or α cells which were small and acidophilic form, and B or β cells which were large and basophilic form. Accordingly, anatomical findings were found in other birds too, with the exception that the spleen lobe was observed as dwindled and too small. Also, the pancreatic exocrine secretions enters into the initial part of duodenum through a single duct. Ostrich's pancreas in both males and females are similar in size and structure. The result of T student in pancreas suggest that there is significant difference in the size of male and females in this organ.
