Blood supply to the stomach of Yorkshire pigs at the stages of postnatal ontogenesis

Abstract

The development of the agro–industrial complex of the Russian Federation is one of the priorities in agriculture. Pig breeding is one of the most profitable branches of animal husbandry. This is due to the fact that pigs have a number of biological features that are successfully used to produce products (pork, bacon, bacon). With the intensification of pig breeding, special attention is paid to scientific approaches to improving pig feeding. In this regard, we set ourselves the goal of the study – to study the arterial vascularization of the stomach in Yorkshire piglets and to determine the morphometric data of the organ at the stages of postnatal ontogenesis. The study was conducted at the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. Cadaver material for the study was delivered to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine from the Idavang Agro pig breeding complex in Nurma village, Tosnensky district of the Leningrad Region. The study was conducted in three age groups, according to the periodization of the life of pigs. To achieve this task, traditional morphological research methods were used, namely: fine anatomical dissection, photographing, vasorentgenography with morphometry in the "RadiAnt" program. During the study, it was found that arterial gastric vascularization in Yorkshire piglets at the stages of postnatal ontogenesis is carried out due to the hepatic and splenic arteries, which are branches of the abdominal artery. The branches of the arteries of the first order branch in a loose type. When conducting a comparative analysis of the morphometric characteristics of the hepatic and splenic arteries and their branches, we came to the conclusion that the diameter of the hepatic artery will prevail over the splenic, and their branches of the first order are diametrically opposed to each other.
