ILLANES, J et al. Histologic Description of the Annexed Glands from the Ostrich Digestive System (Struthio camelus var. domesticus). Int. J. Morphol. [online]. 2006, vol.24, n.3, pp.297-302. ISSN 0717-9502.

In the last decade the upbringing of the ostrich in Chile has increased substantially, for this reason it is necessary to increase the studies to improve the production of this species. The literature only points out studies on the physiology and anatomy of this species. The purpose of this work is to contribute to the knowledge of the normal histology from the annexed glands to the digestive system. This study was carried out clinically using 6 healthy ostriches, of which representative samples of the liver, proventricle and pancreas. Histological sections were realized, mounted and stained for their comparative analysis under low light microscope to describe with those cited in the hen. The histology of the annexed glands from the digestive system is similar to the described in the hen. However, in the liver the arrangement hepatic cords so is in the central vein such as the portal spaces is radial, characteristic not observed in other species. In relation to the histology of the proventricle, the tubular glands are quite, similar to the fundic glands of the mammals. In the submucosa compound tubulosacular glands are observed, with parietal cells. The pancreas doesn't present prominent differences
