Morphometric studies of the skin of adult cows

Abstract

Relevance. The skin of cattle consists of the epidermis and dermis. The dermis, or the skin itself, in turn consists of papillary and mesh layers. However, in the literature we have not found studies on the morphometry of different topographic areas of the skin of cattle. The aim of the study is to conduct comparative morphometric studies of the skin of various topographic zones in adult cows.Methods. For morphometric studies, histological preparations prepared according to the generally accepted method from skin samples of different topographic areas in adult cows were used. The research was carried out at the of the St. Petersburg State University of Veterinary Medicine Department of Pathological Anatomy and Forensic Veterinary Medicine and at the Department of Biology, Ecology and Histology. Morphometric studies of histological preparations were used to study the thickness of the dermis proper, as well as bundles of collagen fibers of the mesh layer of the dermis. The results of the studies were processed using the "Biostat" program.Results. Morphological features of the skin of different topographic areas in adult cows have been established, which are manifested by differences in the thickness of the skin layers and bundles of collagen fibers of the dermis. The morphometry performed allows us to expand the data on the morphological structure of the skin of adult cows.
