The importance of vessel structure were investigated in pathogenesis of laminitis in horse and cattle and existence of artrio – venous shunts in horse was proven although did not demonstrated in cattle. Just a few articles were published on ovine digital arteries. Corrosion casting method is a method of choice for studying different vessel structures that its efficiency in this kind of studies has been proven previously. Hind limbs of 15 lambs of 3 months ages are separated from tarsus joint. By dissection of dorsal metatarsal artery, normal saline and then Resin metacrylat were injected in vessels. After polymerization of Resin metacrylat, hooves put on saturated sodium hydroxide for decomposing of the tissues. In this species, dorsal common digital and common plantar digital arteries are main arteries for blood supply. One branch moves to heel bulb and the other moves to abaxial wall and sole. The third branch of these arteries is responsible for blood supply to perioplic tissue. Proper digital artery pass into nutritional canal of third phalanx in axial surface of this bone and by means of 3 main branches in internal and external wall supply axial and abaxial wall, sole and white line of the hoof. In contrast to Nickel et al the main artery for blood supply of the hooves is dorsal common digital artery, and the caudal arch has only 3 branches.
