Age-related topography of renal vascularization of the goats of anglo-nubian breed

Abstract

The basis for the study was cadaver material from animals obtained during slaughter from the "Gzhelskoe Podvorye", Moscow region. Four age groups were formed. The first group included newborn animals. The second group included animals of one month. The third group included young animals of five or six months. The fourth group consisted of goats, starting from one year old. The age of the animals was determined according to the data obtained from monitor cards. A total of twenty heads were examined. Based on our research, primarily we established that the change in the topography of the right and left kidney in Anglo-Nubian goats exists mainly because of the displacement of the caudal end of the kidney cranially at a distance equal to the length of one or two vertebrae. In both kidneys, the anterior or cranial end does not have a pronounced displacement. Studying kidney syntopia in goats, we found confirmation that the caudal hollow vein together with the abdominal aorta lie dorsally from the kidneys, while the rumen sac is located laterocranially from the left kidney, when it overflows, a slight change in the topography of the kidney can be visualized, and parts of the duodenum are located laterocranially. The data we have established confirm the similarity of the Anglo-Nubian breed of goats with goats of other breeds. By studying the vascularization of the kidneys in the Anglo-Nubian goat breed, we confirmed that the renal blood supply is produced by two renal arteries, each of which is directed to the corresponding kidney "L2-L3". We also found that the severe increase in the diameter of the renal arteries occurs in these animals from 1 to 6 months.
