Age anatomy of the mitral valve of an Anglo-Nubian goat

Abstract

The Anglo-Nubian goat is a British breed of goat bred in the 19th century and widely distributed around the world. In the last decade, there has been an active breeding and introduction of this breed in the Russian Federation and the post-Soviet countries. The study of pedigree anatomy is currently a key direction in the field of domestic veterinary morphology, and the fragmentary literature data on the cardiovascular system of ruminants set us the goal-to study the age patterns of the structure of the mitral valve of the heart of an Anglo-Nubian goat and to establish morphometric data of this heart structure. The dated material presented by the corpses of Anglo-Nubian goats was delivered from the farm of the Moscow region of the Russian Federation "Gzhelskoe Podvorye" to the Department of animal anat omy of the St. Petersburg state University of veterinary medicine, where the study was conducted. The study used three age groups, each of which was represented by four corpses of Anglo-Nubian goats. We used such methods as fine anatomical dissection and morphometry using an electronic caliper "Tamo professional" with a division price of 0.05 mm, manufactured in the United States. As a result of the work, the features of the mitral valve anatomy and its structures in the Anglo-Nubian goat were determined and their linear parameters were determined in the age aspect. The data obtained by us can be used in research works for comparative data analysis, as well as by veterinary specialists in the field of cardiology, surgery and visual diagnostics, as a theoretical basis for practical application.
