Estimation of the diameter of arterial vessels of the multicameral stomach in sheep of the Edilbaev breed at different stages of postnatal ontogenesis

Abstract

The multicameral stomach of sheep of the Edilbaevsky breed, as in other ruminants, according to domestic and foreign authors, has a large number of branches of the main arterial highway, which is due to the functional feature of this organ. The main arterial highway of the multicameral stomach is the abdominal artery. The hepatic artery first departs from it, and then the right cicatricial artery branches off, which goes along the right longitudinal furrow of the scar and exits to its left surface, and the splenic artery branches off the thick right cicatricial artery, and itself in the form of a thin vessel is directed to the spleen. Further, the abdominal artery smoothly passes into the left gastric artery, which goes from the right between the scar and the mesh and, having reached the book, gives the left gastro-omentum artery to the large curvature of the rennet, and the rennet itself anastomoses with the right gastric artery on the small curvature. The methods for the study were fine anatomical dissection, vasorentgenography and computed tomography of the vascular bed with the introduction of a contrasting substance. Corpses and live individuals of sheep of the Edilbaevsky breed aged from 10 days to 14 months, from a private farm in the Leningrad region, served as material for the study. According to the results of the study, it was found that the largest increase in the diameter of the vessels of the arterial bed of the multicameral stomach in sheep of the Edilbaev breed over the entire period of research was observed in the right cicatricial artery. The diameter of other vessels vascularizing this organocomplex increases uniformly at all stages of development. We associate this fact with the active growth of this organ in the first three months of life.
