Abstract
Currently, there are known pig breeds that are characterized by a high rate of growth and development, precocity, fertility, individual structural features, high productivity and economic profitability. The study and breeding of new pig breeds helps to thoroughly analyze the data obtained in comparative, species, age aspects with similar types of farm animals. This fact helps to make a reliable assessment of all economic factors, as well as to analyze the quality of products received from the pig industry. The study was conducted at the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. Cadaveric material for the study was delivered to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine from the pig breeding complex of the Leningrad Region. To achieve this task, traditional morphological research methods were used, namely: fine anatomical dissection with injection of latex vessels, photographing, vasorentgenography with injection of lead meerkat, morphometry in the "RadiAnt" program. The largest main vessels diverting blood from the pig's stomach are the splenic, left and right gastric veins. Ultimately, they are syntopically connected to the small omentum, passing between the leaves of which they open into the portal vein of the liver. The branch of the right gastric vein branches along the loose type, and the splenic and left gastric veins branch along the main one. When conducting a comparative analysis of the morphometric characteristics of the diameter, the splenic vein will prevail over the left and right gastric veins. The results of the study can be used by veterinary specialists, in particular surgeons, to establish operative access to the stomach of pigs.
