The anatomic intestine structure of the ostrich (Struthio camelus var. domesticus) is characterized by a number of essential intrinsic properties related to the climatic conditions of their natural distribution area (desert) and the relatively high fibre content in feed. The objective of the present research was to establish the mass-metric and morphometric parameters of the large and small intestine of the ostrich in the period from the 38th day of embryonic development till the 60th day of life. A total of 42 ostrich specimens of both genders were used, including six embryos obtained on the 38th incubation day and 36 chicks at the age of one day, 3, 7, 14, 30, and 60 days, distributed in groups of 6 birds in each group. The total absolute and relative weight and length of separate segments of the large and small intestine were established. The small and large intestine relative weight of the ostrich chicks increased with the birds advancing in age and reached its maximum on day 30; however, by the age of 60 days the relative weight diminished. A substantial increase in the absolute length of the small and large intestine was observed starting with day 3 of life (p is less than 0.05; 0.001), and with chicks advancing in age it continued to elongate. Assessing the length proportions of separate intestine segments it was found that they had not significantly changed over the whole period of ontogenesis.
