Biologically active centers and the productive potential of sheep

The aim of the research is to localize and give a morphological description of the superficially localized biologically active centers (SLBAC) located on the body of sheep, to study their histological structure and mechanisms of functioning, as well as to assess their impact on the functional systems of the sheep body. 80 SLBAC on the level of bioelectric potential (LBP) are identified on the sheep body The bioelectric activity of SLBAC is in the range from 39 to 72 µa and is closely related to the mass of the Central nervous system of animals and their reproductive function. Topographic search and measurement of bioelectric potential of SLBAC were carried out based on the method of A.M. Guskov, A.V. Mamaev (1996), device type ELAP. Histological preparations were prepared from the samples of the selected tissues and subjected to microscopic examination. Some tissue samples were subjected to biochemical studies. To determine the relationship between the bioelectric activity of SLBAC and the functional state of the Central nervous system of sheep, the division of the brain into departments was carried out, their mass was estimated. Reproductive ability of sheep was estimated by indicators: number of lambs per one lambs; weight of lamb at birth, kg; severity of lambs,%; service-period, days. It was found that sheep SLBAC are located on the border of the transition of the dermis into subcutaneous fat and represent a special morphological substrate consisting of muscular and fibrous connective tissue with many small blood vessels (arterioles, venules), nerve endings and lumens of lymphatic vessels. A relatively high content of calcium and phosphorus in the centers in relation to adjacent tissues was established. The ratio of the centers of the total protein content is as follows №80>65>15>13>64. Increasing the level of biopotential in the centers positively correlates with changes in the mass of the central nervous system and the reproductive ability of sheep.
