Description
Summary:The authors argue the reindeer’s vascular morphology is not sufficiently investigated. They focus on the distal part of the thoracic and pelvic limbs, which the reindeer steps on the ground and hurts it often, as it leads to necrobacterial lesions in summer. In the postnatal period of the reindeer growth, the most intensive one in the length and diameter of the main arteries is observed in the first year, especially in the first month. During this period, the newborn deer gets into the new conditions of existence and the organs of movement become more and more functional. By the age of 3 - 3.5 years, the growth of the main arteries in length is almost over. The paper explores the features of blood supply of the thoracic limbs of a domestic reindeer, caused by the prominent growth of the second and fifth fingers. The absolute growth of arterial length in newborns and deers aged 0.5 months is 0.6 cm per day. In the following years of life, the length is reduced to 0.03 cm in the reindeers aged 3 y.o. The relative diameter of the arteries to the limb length in the postnatal period decreases from 4.4% in newborns to 3.3% in old deer. The irregularity of changes in the absolute and relative development of the thoracic limb arteries can be explained by different growth of blood vessels, bones, joints and limb muscles. У северного оленя недостаточно изучена морфология сосудистой системы. Практический интерес вызывает дистальный отдел грудной и тазовой конечностей, которым олень опирается на почву и часто его травмирует, что в летнее время приводит к возникновению и развитию некробактериозных поражений. В постнатальный период развития наиболее интенсивный рост длины и диаметра магистральных артерий отмечается в первый год жизни животного, особенно в первый месяц. В этот период новорожденный телёнок попадает в новые условия существования, усиленно начинают функционировать органы движения. К возрасту 3–3,5 года рост магистральных артерий в длину практически заканчивается. В данной работе представлены особенности ...
