Paska M. Functional status and productivity of young Volynj and Polissja beef breeds depending on the type of higher nervous activity

The thesis deals with the results of a systematic search of the functional state of bulls organism of Volynj and Polissja fattening beef breeds depending on the type of higher nervous activity by clarifying the dynamics of physiological parameters of the organism, the manifestation of behaviors reaction and the level of endocrine-metabolic processes. It was determined the degree and the character of changes of general adaptive-compensatory reactions of bulls of Volynj and Polissja beef breeds and for the first time it was discovered the concept of the relationship of individual components of the system of organism homeostasis with typological characteristics of higher nervous activity (strength, balance and mobility of excitation and inhibition in the cortex of cerebral hemispheres) under physiological conditions. The data concerning the formation of adaptive reactions of animals organism depending on the type of higher nervous activity, create the background to form highly herds of animals, the correction of high body resistance and increase productivity of bulls of Volynj and Polissja Beef breeds
