Shaposhnik V. Participating of suckling gland of cows of different types of higher nervous activity is in the exchange of lipids during a lactation

The Thesis is devoted to the studying of the impact of typological peculiarities of higher nervous activity on the lipid metabolism in cows during the lactation. As a result of conducted investigation the role of the higher nervous activity type in the synthetic processes of the mammary gland was established. It was proved that the strength of excitation and inhibition processes has an effect on the intensity of lipid metabolism and its components. The content of lipid components is associated with the strength, balance and mobility of processes in cerebral cortex. The formation of the fatty acids (volatile, saturated and unsaturated) in blood and milk depends on the typological peculiarities of the nervous system and is more fully realized in cows with strong balanced mobile type. Established that the type of higher nervous activity affects on the content of separate volatile fatty acids in bovine milk. It was found the reliable correlations between the strength of nerve processes and the content of acetic, butyric, propionic, and valeric acids. The highest negative correlation was noted between the balance of nerve processes and the amount of unsaturated linoleic and eicosapentaenoic acids in the blood of cows. The content of arachidic, eicosanoic, eicosapentaenoic acid was correlated with the mobility and balance of nerve processes. The absorption of acids by the mammary gland from the blood is more intensive in cows with strong types of higher nervous activity.
