Studies on localization and distribution of enteroendocrine cells (EECs) are important for better understanding of their role in the ontogenetic development of intestines. Information about the distribution of the most important endocrine cells in the digestive tract of the ostrich is very limited; therefore, the aim of the present study was to identify gastrin and somatostatin EECs in the small intestine of the ostrich ( Struthio camelus var. domesticus ) chicks at different ages. Six embryos along with 42 ostriches of both sexes from hatching up to 60 days post‐hatching, including six embryos, were obtained from an ostrich farm in Latvia. Duodenum, jejunum and ileum were investigated using routine histology and immunohistochemistry methods. Gastrin and somatostatin EECs were examined in 10 microscopic fields of the intestinal mucosa in each tissue sample. The cells were detected in all age groups as well as the embryos. The number of both types of EEC in the mucosa of the ileum was significantly lower ( p < .01–.05) than in the duodenum. The present study suggested that the EEC may have a role in the development of the mucosa of the intestinal tract of ostriches with possible involvement in the development of the digestive functions.
