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.
