Postoi R. Cortical and Vegetative Regulation of Metabolism in Dry Sows and Methods for its Correction

The dissertation is devoted to scientific substantiation of the role of cortical and vegetative mechanisms in the regulation of metabolism in dry sows’ organism, peculiarities of adaptation processes depending on vegetative status and typological features of higher nervous activity, development of method for metabolism correction. It was found that the strength, balance and mobility of nerve processes in the cerebral cortex have a significant impact on the metabolic parameters in blood of dry sows under physiological conditions. The tone of the autonomic nervous system has a less pronounced impact on the metabolic processes in sows’ organism and is mainly interrelated with carbohydrate metabolism. It is established that the activity of enzyme systems in dry sows’ organism depends on the individual characteristics of the nervous system. During the period of adaptation to the exposure to the technological irritation, the role of cortical and vegetative mechanisms in the regulation of metabolic processes in organism of dry sows increases. This is confirmed by the data of analysis of variance and correlation analysis, which showed a significant dependence of the dynamics of protein, lipid and carbohydrate metabolism on the strength, balance and mobility of the excitation and inhibition processes in the cerebral cortex. At the same time, the exposure to the technological stimulus increases the influence of the autonomic nervous system tone on protein and lipid metabolism in dry sows’ organism. It was found that the typological features of the nervous system determine the speed of adaptation processes in dry sows’ organism. Studies have shown the possibility of using a micellar system with encapsulated α-tocopherol acetate to correct physiological and biochemical processes in sows’ organism and improve productivity under industrial conditions. It has been found that the effect of the vitamin preparation has a different manifestation in animals depending on the type of higher nervous activity and vegetative status. In addition, the use of a micellar system with encapsulated α-tocopherol acetate alters the cortical and vegetative regulation of metabolic parameters in the blood of dry sows.
