Age-related patterns of the arterial bed of the forearm area in black Pushkin sables

Abstract

Fur farming is a unique, young and developing branch of animal husbandry in the Russian Federation, which provides fur products not only to the country's market, but also exports 5-10% to non–CIS countries. Among fur farming, the most relevant is the breeding of sables, since the combination of their biological development features ensures high productivity of fur raw materials. Pathologies found in the structure of the limbs (joint deformities, muscle weakness, incorrect finger placement) lead to decreased activity, stress, injury, and even death of puppies in the first weeks of life. Therefore, modern farms strictly control the anatomical features of animals at the breeding stage: individuals with defects are excluded from breeding, giving preference to those whose morphological characteristics meet health standards. The aim of the study was to establish and study the course and branching of the arterial bed of the forearm area in Black Pushkin sables in the age aspect and to determine the morphometric parameters of the main vessels. The object of the study was male sables aged 15-20 and 36-40 months from birth. The number of animals studied was five in each group. The study was carried out using such methods as fine anatomical dissection, morphometry, photographing, vasorentgenography, computed tomography. During the study, the main arterial highways were identified, as well as their course and branching on the thoracic limb in the forearm area in black Pushkin sables in the age aspect. The main dynamics of vascular diameter increase is observed by an average of 1.52 times in individuals at 36-40 months of life, compared with sables 15-20 months from birth. This fact is due to the fact that, despite the cellular content of animals, sables are active animals, and the pectoral limbs perform a number of vital functions, in which their need increases with age.
