The reindeer is a representative of the order artiodactyls, most of the individuals inhabit the territory of the Northern hemisphere. It is a significant hunting and commercial species, and reindeer husbandry is the main branch of animal husbandry in the conditions of the Far North. The morphology of the reindeer has always been of interest to researchers. In different years, the architectonics of the vascular bed of the reindeer have been studied by many researchers [3, 4]. However, in the available literature sources, we have not found data concerning arterial blood supply to organs and tissues in reindeer fetuses. In the prenatal period of development, there is a restructuring of organs and tissues, and with them the vascular bed. The aim of the study was to study the arterial vascularization of the pelvic limb in a reindeer fetus, to give morphometric characteristics to the arteries. The studies were conducted on 5 reindeer fetuses at the age of 4.0-4.5 months. The fruits were delivered to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine from reindeer herding farms of the Republic of Sakha (Yakutia). The fruits were extracted after the slaughter of vazhenok for household needs. Classical methods were chosen as research methods: fine anatomical dissection, morphometry, photographing and vasorentgenography. During the study, it was found that the main arterial trunk of the pelvic limb in a reindeer fetus is the external iliac artery. Skeletotopy and angioarchitectonics of the main arteries of the pelvic limb of the reindeer fetus have typical patterns characteristic of adult animals. Morphometric parameters of the arteries are consistent with the topographic position of the muscle groups – a greater number of large arterial branches are noted in the hip area. The presence of collateral blood flow in the foot area is noted – the vessels of the dorsal and plantar surfaces are connected to each other due to the perforating metatarsal and perforating metatarsal arteries, as well as at the confluence of the axial and non-axial finger arteries.

The nervous system is one of the leading integrating systems of the body. In combination with the cardiovascular and endocrine systems, it unites the body into a single whole. The nervous system controls the level of adaptive reactions of a living organism to changing environmental conditions. The Nile bat (Rousettus aegyptiacus) is a typical representative of the order bats. The purpose of our study is to study the macromorphology of individual anatomical structures of the brain of the Nile bat (Rousettus aegyptiacus). The material for the study was four different-sex animals of the Nile bat species (Rousettus aegyptiacus) aged 10-14 years, obtained from private veterinary clinics. The methods for studying the brain of the Nile bat were: fine anatomical dissection, morphometry, photographing, weighing. The work was performed on the basis of the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. As a result of the study, it was found that due to the strong development and large size of the auditory posterior tubercles of the quadrilateral, it is possible to judge the predominance of the auditory analyzer, while the anterior tubercles of the quadrilateral have a relatively small size, most of the structures of the visual analyzer are contained in the neocortex. It was found that there is no division of the cerebellar fragment into anatomical structures in the brain, and the size of the flocculonodular lobe of the cerebellum in this species is on average 1.30x1.10±0.15x0.10 mm. The absence of pronounced lobes and furrows was revealed, and the Nile bat (Rousettus aegyptiacus) belongs to lysencephalic animals. The obtained materials can be used as a reference material for continuing research on the brain of the Nile bat (Rousettus aegyptiacus), as well as in comparative morphology and physiology of humans and animals.

The study of disease etiology plays a critical role in modern veterinary medicine and is of great importance for animal health. Liver pathologies in cattle are of great importance in agriculture. Liver pathologies can have different causes, including infectious diseases, parasitic infestations, and the consequences of poisoning or improper feeding. The search and processing of scientific publications were carried out according to H. Snyder’s recommendations for writing review articles. Only a deep understanding of the causes, mechanisms, and risk factors can lead to the development of effective methods for the prevention, diagnosis, and treatment of liver pathologies, which helps improve the productive abilities of cattle.
