Anatomical and topographical features of the area of pelvic bones of dorper sheep

Abstract

Movement is a characteristic and inherented property of the animal organism. Without the implementation of musculoskeletal work, it becomes impossible for the animal to move in the environment, search for food, protect themselve and procreate. This work in the body is performed by the musculoskeletal system, which accounts for most of the body weight. The basis for the research at the Department of animal anatomy of Saint Petersburg state university of veterinary medicine was post-mortem material from animals slaughtered at the farm "Gzhelskoe Podvorye", Moscow region. Three age groups were formed. The first group included newborn animals. The second group included young animals of five to six months. The third group consisted of sheep from one year and older. During the study, a set of anatomical methods was used, including: fine anatomical dissection, maceration, computer tomography and macrophotography. Based on our research, we first established anatomical and topographical features of the pelvic area of dorper sheep. These features have a common anatomical pattern, which is characteristic for ruminants. However, dorper sheep are characterized by typical topographical breed features of that area, determined by their genetic predisposition. The main morphometric parameters of the pelvic bones of dorper sheep reach their maximum values by the age of one year and older, while the most intensive growth of the pelvic area is typical for the age period from five to seven months to a year.
