The arterial blood supply of the wing in domestic fowl was studied to investigate the course and distribution of the subclavian artery as a trial to extend our knowledge on the vascular anatomy of poultry which had received a little attention in the field of veterinary comparative anatomy. The present work was carried out on eight adult, apparently healthy chickens of both sexes. The birds were slaughtered and the subclavian artery of five chickens was cannulated and flushed with warm normal saline (0.9%), then injected with red gum milk latex. The specimens were subjected to fine dissection to demonstrate the origin, course, relations and distribution of the subclavian artery. The other three chickens injected with Urograffin for x-ray purposes. The arterial supply of the thoracic limb of the fowl was formed mainly by the pectoral trunk and axillary artery. The obtained results were photographed, described and discussed with their corresponding features of authors who performed earlier studies in other avis breeds.
