Vascular bed of the shin region of goats in the age aspect. Legal regulation in veterinary medicine

The study of the vascular system, in particular the arterial bed, is a fundamental basis for the development of veterinary medicine, especially in such fields as surgery, orthopedics and traumatology. The shin area in breeding farm animals, including goats, is subject to high functional loads and the risk of injury, which necessitates a detailed knowledge of its blood supply. The purpose of the study is to study and analyze the topography, branching and age dynamics of the shin arteries in goats using the example of the Anglo-Nubian breed, as well as to assess the practical significance of research in the work of a veterinary surgeon. The study was conducted at the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. The study was conducted in three age groups: newborn baby goats; young animals 5-6 months old; adult animals. To achieve this goal, traditional morphological research methods were used, namely: fine anatomical dissection, photographing, and vasorentgenography with morphometry in the RadiAnt program. According to the results of the study, it was found that the arterial bed of the shin in Anglo-Nubian goats is a complexly organized system with certain age-related patterns of development. The popliteal artery serves as the main source of blood supply, giving rise to the cranial and caudal tibial arteries, which, in turn, provide vascularization of muscle groups, bones and joints. The safin artery plays not only an auxiliary, but also a collateral role. Morphometric data convincingly demonstrate intensive vascular growth in the first months of life, which must be taken into account when developing surgical techniques for young animals.
