Background: Rabbits (Oryctolagus cuniculus) are lagomorphs belonging to the Leporidae family. They are an important source for humans feeding industry and widely used in laboratory experiments. In the biomedical investigation fi eld, the rabbit contributes for the production of several scientifi c studies. Since information about the rabbits morphology is rare, especially what refers to abdominal vascularization, this work had the objective to systematize and describe the parietal collateral and terminal branches of the abdominal aorta in New Zealand rabbits.Materials, Methods & Results: Fourteen male and sixteen female New Zealand young adult rabbits (Oryctolagus cuniculus) were used. Animals were euthanized with T 61, administered via an intrapulmonary injection. Skin was removed, thoracic cavity opened in plastron, thoracic aorta cannulated, according to blood fl ow, and the two cranial and caudal cava veins sectioned near the heart. System was washed with saline solution and heparin and fi lled with red latex. Animals remained immersed in running water, for 90 min, and the trunk was transversally sectioned, near the last thoracic vertebra. The abdominal cavity remained closed and formaldehyde was administered via an intraperitoneal injection. Samples were fi xed in formaldehyde for seven days, the abdominal cavity opened, the viscera removed in block and the arteries d
