In order to investigate the effect of cecal vascular severation on cecal nitrogen excretion, the present experiment was carried out using the intestinal perfusion technique on 70-85 day-old Single Comb White Leghorn cockerels. The following results were obtained; The nitrogen excreted into the cecum was markedly decreased by the severation of caudal-, middle- and cranialileocecal arteries and veins. Cecal branches of caudual- and cranial-mesenteric blood vessels did not play a significant role in nitrogen excretion into the cecum. The amount of nitrogen excreted into the cecum through the region of caudal-ileocecal vessels was about 1.5 times as much as that through the region of middle- or cranial-ileocecal vessels. From these results, it can be assumed that the ileocecal blood vessels played an important role in the excretion of nitrogen into the cecum, in the most part of which was in non-protein form.
