Architectonics and morphometry of the extra-organ arterial bed of the small intestine of edilbaevskaya sheep in three age groups of postnatal ontogenesis

Abstract

In the modern world, sheep farming is one of the leading areas of cattle breeding. Large holdings that focus on raising sheep, quite often meet with problems of diseases of the digestive system. Sheep of the edilbaevskoy breed are one of the most common breeds. A detailed study of all the organs of the animal will give a more correct approach to the treatment of non-infectious diseases of the digestive system. For adequate treatment, surgical access and differentiation of diseases of the gastrointestinal tract, the veterinarian must clearly know the topography of the intestine, the patterns of its blood supply to the intestine as a hollow organ. For this we have conducted a series of studies demonstrating age-related changes of the blood supply to the small intestine and the regularities of the branching arteries of the small intestine in sheep edilbaevskoy. The basis for the study was the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine, the material for the study was obtained from healthy animals from a farm in the Leningrad region. Three groups of different ages were formed to conduct the study. The first group is newborn animals up to 14 days old. The second group – young animals of 5-7 months of age. The third group includes animals from one year and older. The conducted research includes the complex anatomical methods: waterintensive, subtle anatomical dissection, photography, morphometry. In the conducted studies, we first established the architectonics of the arterial bed of the small intestine of Edilbaevsky sheep in different age categories. It can be noted that the obtained data have general anatomical patterns of the course of vascular branching, characteristic of ruminants. Sheep edilbaevskoy are characterized by pronounced breed features topographic relationship of the body to the neighboring anatomical structures of the abdomen.
