The growth of rational ostrich breeding and their byproducts has attracted interest from researchers to increase the studies in this animal. Thus, basic research areas, such as morphology, become necessary to provide the applied areas with knowledge. Aiming to contribute to the knowledge on the vascular arrangements of the adrenal glands, 30 ostriches (Struthio camelus) were used, four days old, who had their arterial components marked with a 50% stained aqueous solution of Neoprene Latex ¨ 450 ¨ and fixed in a 10% diluted solution of formaldehyde. The coelomic cavity was exposed for identifying these glands, which are paired organs that are covered by loose connective tissue, symmetrically arranged in the two antimeres, laterally to the descending aorta, caudally to the lungs, and cranio-medially to the cranial lobes of the kidneys. The arterial blood supply, in both antimeres, is derived from the right and left adrenal arteries, the right and left cranial renal artery branches, and the right branches of the descending aorta. Regardless of the origin, the number of branches going to the adrenal glands ranged from one to two and one to three respectively, in the left and right antimeres.
