Comparative study of the arterial supply of the stomach of the white lipped peccary (Tayassu pecari) and of the collared peccary (Tayassu tajacu) [Linnaeus, 1789]

Abstract

To carry out the study, the stomachs of 36 animals were used, from which 28 were white lipped peccary and 8 colored peccary. The celiac artery was injected with colored neoprene - latex 650, through the thoracic portion of the aorta, so as to fill the arterial ramifications of this vessel, which were directed to the stomach chambers. Then the samples were fixed in a 10% aqueous formol solution, to be carefully dissected and examined. The results show that, in both species, this organ is supplied by the terminal branches of the celiac artery. The conclusions listed in this research are based on the statistics of this distribution pattern.
