Thesis is devoted to the studying of degree and nature of nervous system typological peculiarities influence on metabolism of certain macro- and microelements in bovine organism. The central mechanisms regulating the content of macro- (sodium, potassium, phosphorus, calcium and magnesium) and microelements (cuprum, manganese, iron and zinc) in bovine blood, which depend on the typological features of its central nervous system (strengths, balance and mobility of excitation and inhibition processes) are established. The degree and nature of the influence of strength, balance and mobility of excitation and inhibition processes in the cerebral cortex on the content of certain macro-and microelements in bovine blood are established. The influence of strength of the cortical processes on sodium, potassium, phosphorus and magnesium content is determined – η²x=0.21–0.50 (P<0.05–0.001). The balance and mobility of the cortical processes reliably limits only phosphorus and magnesium content – η²x=0.27–0.48 (P<0.05–0.001). Direct correlation relationships of strength of cortical processes with the content of potassium, phosphorus and magnesium were established – r=0.62–0.75 (P<0.01–0.001), balance with the content of phosphorus and magnesium – r=0.55–0.68 (P<0.05–0.001) and mobility only with phosphorus content – r=0.58 (P<0.01). The influence of strength of cortical processes on iron, zinc, manganese and cuprum content – η²x=0.21–0.44 (P<0.05–0.001) is proved. The balance of cortical processes has a significant effect on iron, zinc, and cuprum content – η²x=0.21–0.37 (P<0.05–0.01). The mobility of the cortical process’s limits only zinc content – η²x=0.66 (P<0.001). The strong direct correlation relationships of strength of cortical
processes with the iron, zinc, and cuprum content are established – r=0.51–0.63 (P<0.01–0.01), the balance with the content of iron and zinc – r=0.44–0.63 (P<0.05–0.01) and mobility only with the content of zinc – r=0.65 (P<0.01). The ceruloplasmin content in blood serum of cows with strong unbalanced and weak types of higher nervous activity in the serum is lower by 9.4 % (P<0.05) and 15.6 % (p<0.05) than indicators in cows with strong balanced mobile type. The transferrin saturation by iron in blood of cows with strong, balanced, mobile type of higher nervous activity was higher by 11.5 (P<0.01) and 19.8 % (P<0.01) than the indicators of strong unbalanced and weak type animals. The impact of the technological stimulus on mineral homeostasis in bovine organism is established, which to a certain degree is determined by typological characteristics of cortical processes in cows. In animals of a strong unbalanced type, under the impact of the technological stimulus found the decrease of iron, zinc, manganese content by 9.2–13.1 % (P<0.05–0.001) and in weak type cows – iron, zinc, manganese and cuprum by 8.0–16.4 % (P<0.05–0.001). The influence of excitation and inhibition processes in the cerebral cortex on bovine milk productivity was established. Reliable correlations of bovine milk productivity with iron, magnesium, cuprum, zinc, phosphorus and potassium content in its blood were established – r=0.53–0.67 (P<0.05–0.01).
