The Eurasian lynx is widely popular among wild feline animals. It is often the object of domestication and it is bred on fur farms for the extraction of fur products. Heart vascularization in domestic and wild mammalian animals has not been studied enough and is still an urgent area of research, our goal was to study the anatomy of the left coronary artery of the Eurasian lynx heart and establish its anatomical and topographic patterns. To study the anatomy of the heart, the corpses of the Eurasian lynx were taken at the age of two or three years. In total, five corpses of the Eurasian lynx were examined. Cadaver material was delivered from private fur farms of the Leningrad and Moscow regions to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. To study the vascularization of the heart of the studied animals, classical and modern anatomical techniques were carried out, such as fine anatomical dissection and the manufacture of corrosive preparations using latex. According to the results of the study, it was found that the left coronary artery in the Eurasian lynx is sufficiently developed and supplies blood to the structures of the left and right half of the heart, and the subsinuous artery does not belong to the branches of the left coronary artery, in connection with which it can be concluded that the uniform type of blood supply in the Eurasian lynx. The results of the study can be used by veterinary specialists, in particular surgeons, to establish operative access to the heart in the form of a pattern of branching of the left coronary artery of the heart in the Eurasian lynx.

“…Причем, первая из них является ветвью левой венечной артерии, а вторая -правой. Таким образом, получается, что в независимости от типа кровоснабжения сердца у животных по литературным данным отечественных и зарубежных авторов паракональная артерия всегда принадлежит левой венечной артерии, а субсинуозная артерия -правой [1,5].…”

“…Поэтому предотвращение возникновения таких симптомов, а также повышение продуктивности зависит от сочетанного применения йода и селена у сельскохозяйственных животных, содержащихся в хозяйствах, находящихся в биогеохимических провинциях [9]. Изучение динамики показателей крови при различных физиологических и патологических состояниях дает возможность оценить клинический статус животного [1,5,8]. Анализ биохимических параметров крови животных позволяет судить о состоянии углеводного, белкового и липидного обменов [2,3,10].…”

The variability of branching of the coronary arteries of the heart determines the dominance of one artery over the other in the left or right coronary types of blood supply. Thus, in the left coronary type, the right coronary artery is poorly developed and vascularizes a small area of the heart, or may be completely absent. The same phenomenon, respectively, can be observed in the right-handed type with the left coronary artery. The German Shepherd is a typical representative of the leftcoronary type of blood supply to the heart, like all other representatives of its species. The aim of our study is to study the vascularization of the left half of the German Shepherd heart. To study the vascular bed of the German Shepherd heart, ten corpses of dogs of this breed were obtained at the age of two to three years after forced euthanasia. The cadaveric material was delivered from private clinics in St. Petersburg to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. The vascular bed of the heart of a German Shepherd was investigated by applying such methods as fine anatomical preparation with filling the vascular bed with latex, as well as corrosion treatment of the obtained material. As a result of the study, it was found that the source of vascularization of the left half of the heart is the left coronary artery and its main arteries, including the paraconal, subsinus, circumferential, left interventricular and left diagonal arteries. The subsinusoid artery is a branch of the left coronary artery, while the right coronary artery does not reach the region of the subsinus sulcus. The interventricular septum of the heart in a German Shepherd is completely vascularized by branches of the left coronary artery. The main artery in this case is the left interventricular artery. The results obtained confirm that the presence of a left-coronary type of blood supply to the heart in an animal does not determine that the region of the subsinus sulcus will be vascularized by the branches of the right coronary artery.
