Anatomical and topographic features of the arterial kidney bed in males of the black Pushkin sable breed in the age aspect

Currently, diseases of fur–bearing animals associated with the urinary tract of various ethologies are widespread, which affects the development of the entire organism, and as a result, the quality of the products obtained is deteriorating - fur. Without knowledge of the morphological features of the structure of the urinary organs in the age aspect, it is problematic to diagnose diseases and pathologies, as well as to carry out timely treatment. The aim of the study was to study the anatomical and topographic features of the course and branching of the renal arteries of males of the black Pushkin breed in the age aspect, as well as to determine their morphometric parameters. This will allow us to better understand the mechanisms of adaptation of the vascular system to specific conditions of detention and subsequently develop recommendations for optimizing the breeding conditions of sables. The object of the study was male sables aged 15-20 and 36-40 months from birth, with six heads in each group. To achieve this goal, a set of research methods was used: fine anatomical dissection, morphometry, photographing, vasorentgenography, manufacture of corrosive preparations, computed tomography. The study established the main arterial routes, as well as their course and branching of the renal arteries in male sables of the black Pushkin breed in the age aspect. The main dynamics of vascular diameter increase is observed by an average of 1.32 times in individuals at 36-40 months of life, compared with sables 15-20 months from birth. The established data demonstrate normal age -related changes in the vascular system characteristic of the growth period of young sables of the Pushkin breed. A 51% increase in the distance between the renal arteries and a 50% increase in the diameter of the aorta is a direct consequence of the overall increase in body size and the development of the vascular system. This ensures an adequate blood supply to growing organs by increasing the length of the vascular bed and the diameter of the main vessels to allow more blood to pass through. At the same time, the fundamental proportions and patterns of vascular branching are preserved (a constant coefficient of narrowing of the aorta after the departure of the renal arteries).
