ANATOMICAL AND TOPOGRAPHIC FEATURES OF BRANCHING OF MAMMARY GLAND ARTERIES IN AN ANGLO-NUBIAN GOAT BREED

Abstract

Milk productivity is one of the most important economically useful indicators for which selection is carried out. The level of milk productivity depends on heredity, physiological state, conditions of feeding and use of animals. All other things being equal, the level of milk productivity depends on the breed of the animal. To date, many studies have been conducted on vascular vascularization of the mammary gland in ruminants, but few of them concerned the application of anatomical features of the course and branching of vessels in possible surgical and obstetric-gynecological interventions. In connection with the above about the relevance of breast research, we set a goal to study the anatomical and topographic features of the branching of the arteries of the mammary gland in a goat, and use the Anglo –Nubian breed as a model. The study was conducted on the basis of the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. The dated material was delivered from the farm of the Moscow region of the Russian Federation "Gzhelskoe podvorye". The age of the studied animals was 1 year and older. The age was determined from the words of the chief veterinarian of the farm "Gzhel farmstead", as well as according to the bonus cards and according to the dental formula of the methodology of Professor I.I. Kalugin, a total of 15 individuals were studied. During the study, such methods as: fine anatomical dissection, vascularization, morphometry, photographing were used. According to the results of the study, species and breed anatomical and topographic features of the branching of the arteries of the mammary gland in the goat of the Anglo-Nubian breed were established. The main sources of breast vascularization in the Anglo-Nubian goat breed have been identified. These studies can be used by veterinary specialists in farms and large livestock complexes for breeding goats during surgical and obstetricgynecological manipulations.
