The species that belong to the Rodentia and Lagomorpha orders present visible differences on the morphology in the digestive tract, especially in the small intestine. The purpose of this study was to obtain a complete anatomical description of the differences between these two species and also to complete the knowledge about chinchillas. It is known that both chinchillas and domestic rabbits have lately become animal models for research, but also raised as a pets.The reseach has been carried out in the Comparative Anatomy Laboratory of the Faculty of Veterinary Medicine in Cluj-Napoca. The study was performed by dissection and macroscopic examination on five chinchillas and five rabbits. Both species have the small intestine divided into: duodenum, jejunum and ileum. In rabbits, the duodenal ampulla is not so developed as in chinchillas. In chinchillas, the ileum, the ascending segment of the large intestine and the cecal body, do not make a common block. But, in rabbits, because of a greatly developed ileocecal ligament, the ileum is attached to both of the aforementioned anatomical formations. Also, the terminal segment of the ileum of this species is represented by a sacculus rotundus, which is absent in chinchillas. Following this study, we observed differences in the morphology of the small intestine segments of these two species, that are particulary important in understanding and, also, solving the various digestive disorders that are usually found in both species.
