Architectonics of the arterial system of the ruminant stomach of edilbaev sheep in age aspect

Sheep farming is one of the leading agricultural industries in the Russian Federation. A modern veterinarian needs to know the functional principles of all organs and systems of the animal body to understand the etiology and build cause-and-effect relationships of the occurrence of certain noninfectious diseases. Most of these diseases occur in the digestive tract (stomach, intestines). The purpose of this study is to study in detail the age-related patterns of blood supply of the stomachs of edilbaev sheep. The basis for the research at the Department of animal anatomy of the Saint Petersburg state university of veterinary medicine was post mortem material from animals slaughtered at a farm in the Leningrad region. Three age groups were formed. The first group included newborn animals. The second group included young animals of five to six months. The third group consisted of sheep from one year and older. The age of the animals was determined according to the data obtained from monitor cards. During the study, a set of anatomical methods was used, including: fine anatomical dissection, vaso-rentgenography, and photographing. Based on our research, we first established the architectonics of the arterial system of the stomachs of edilbaev sheep in the age aspect. These features have common anatomical patterns of the course and branching of blood vessels, typical to ruminants. However, the edilbaev sheep breed is characterized by breed features of skeletal and vascular syntopia, determined by their genetic predisposition. The main arterial line of the multicameral stomach of edilbaev sheep is the ventral artery, which in the course of its topography is divided into additional incoming vessels for all the pre-ventricules and the true stomach. The main morphometric parameters of vascular diameter reach their maximum values by the age of one year and older, while the most intensive increase in the caliber of arterial vessels of the multicameral stomach is typical for the age period from the newborn period to five to seven months.
