Rabbits have been used as an experimental model in many studies. These studies are important for not only for veterinary clinicians, but also for researchers in different fields. The aim of this research was to describe gross morphological measurement, shape and arterial supply of the adrenal glands in healthy New Zealand rabbits. Dissections were performed in 30 adult rabbits, 15 males and 15 females, without macroscopic adrenal pathology. Adrenal measurements were made with a digital caliper: length, width, and thickness. The origin of the adrenal arteries was also determined. Both adrenal glands were localized cranially to the respective kidneys. The mean of the right adrenal gland was 0.88 cm length, 0.42 cm width and 0.16 cm thickness; the left gland measured 0.72 cm, 0.46 cm, and 0.17 cm, respectively. The right gland was significantly more elongated than the left (p = 0.0003) and the means of the measurements did not differ between sexes. Most of the right adrenal glands had a piriform shape (73.3%), whereas most of the left gland exhibited a “bean-shaped” aspect (60.0%). The arterial supply was found to arise from different arteries:  lumbar, aorta, renal, caudal mesenteric, and testicular or ovarian. Comparatively, the descriptions of shape, position and arterial irrigation of the adrenal gland in rabbits are similar to those available in rodents. The data from the present investigation will assist in the interpretation of pathological and / or experimental findings in New Zealand rabbits.
