The arteries supplying the left adrenal gland were determined in 12 mature sheep and goats of both sexes and different breeds. The adrenal branches arose from the first and second lumbal arteries in both species but in one goat they originated from the first lumbal artery while in another from the last intercostal artery. The cranial adrenal branches arose from the celiac artery in 8 sheep, both from the celiac and cranial mesenteric arteries in 3 sheep and from the common celiacomesenteric trunk in 1 sheep. In all goats the cranial adrenal branches originated from the cranial mesenteric artery. The caudal adrenal branches arose singly from the renal artery in all sheep and goats. In both species any branch from the aorta or caudal phrenic arteries to the adrenal gland was not seen.
