Features of the blood supply to the fingers thoracic limbs in cows of black-motley breed

Abstract

The primary purpose of my thesis is to research the particularities of the blood circulation in the digits of the thoracic limb of the Black-Motley cows. The research methods used in this study included vaso-roentgenography.The infusion into arterial line was conducted through the medial palmar artery. It was established that the arterial supply of the digits of the forelimb in the Black-Motley cows is from the three great vessels. The arteries supplying the third digit are the well-developed third common palmar digital artery and lateral branch of the special third medial palmar digital artery, as well as the underdeveloped special dorsal third digital artery. The arteries supplying the forth digit are the well-developed forth common palmar digital artery and lateral branch of the special medial forth palmar digital artery, as well as the underdeveloped special dorsal forth digital artery. Considering the development of these great vessels, we find the dorsal approach for surgical treatment of the digits in this breed most expedient.
