Histological, morphometric, electrophysiological features of biologically active centers of sheep and their meat

One of the main tasks in the field of animal husbandry is the use of hidden biological resources of the body of farm animals in the production. The studies of many authors have established that on the surface of the animal body there are areas with altered or specific histological and functional characteristics - superficially localized biologically active centers. The purpose of this work was to study histological, morphometric indicators of biologically active centers of sheep as functional regulatory elements of the compensatory-adaptive system of animals with different meat productivity of the organism. The object of the study was Romanov sheep at the age of 8 months old. In the experimental animals, the level of functional activity of the SLBACs was studied by measuring the level of biopotential in the centers № 5, № 10, № 59, № 64. Histological and morphometric parameters of superficially localized biologically active centers (SLBACs) were studied in the experiments, their bioelectric potential was measured and the meat productivity of sheep was evaluated. As a result of the research, it was found that the centers have clearly defined boundaries of the area. Intensive development of the vascular network, nerve trunks and endings is noted in the area of the location of the SLBACs. The cellular density of the dermis surrounding these formations is more intensive compared to intact skin and is represented by elements of the leukocyte series, which affects the formation of bioelectric potential in the centers. It has been established that the level of bioelectric potential of SLBACs No. 5, 10, 59, 64 of the experimental sheep has a direct relationship with the indicators of their meat productivity. According to the level of bioelectric potential of the SLBACs, it is possible to predict and determine the indicators of sheep meat productivity in life without resorting to the use of special equipment.
