Arterial system of the swine femoral area o of breeds Landrace and Duroc in comparison

The study was carried out at the Department of animal anatomy of the St Petersburg state Academy of veterinary medicine. Animals body material for the study was delivered to the Department of anatomy of animals FGBOU VO "Saint-Petersburg state Academy of veterinary medicine" from a swine-breeding complex "Idavang agro" village Nurma, from Tosnenskiy district of Leningrad region. Animal material objects for this study included three age groups, according to the periodization of the swine life (V. Zhelev, 1976; D. C. Blood, 1988; Kudryashov A. A., 1992) - newborns 1-7 days (early neonatal period); newborns 10-14 days (late neonatal period); newborns 20-28 days (late neonatal period). Body weight from 2000 to 2500 kg. To achieve our aim were used complex of traditional anatomical methods: fine anatomical dissection, lazarettgasse, photography and morphometry. In order to describe anatomical terms the international veterinary anatomical nomenclature (fifth edition) was used. The length measurements were carried out using an electronic caliper Stainless hardened with the size of division 0.05 mm. In the study of the arterial system of the femoral area of pigs of Landras and Duroc breeds in the early stages of postnatal ontogenesis, we noticed that the General architectonics of arterial vessels is similar to venous. Arteries in the femoral region of both breeds of pigs are located topographically correctly; the diameter of the vessels varies with an increase in the proximal links and a decrease in the distal ones. There is no asymmetry of arteries between the right and left sides. In the age aspect, the main increase in the diameter of the arteries occurs in the period from 10-14 days of age to 20-28 days of postnatal ontogenesis.
