INFLUENCE OF HIGHER NERVOUS ACTIVITY TYPES ON THE CONTENT OF LIPID PEROXIDATION PRODUCTS IN BOVINE BLOOD
The results of studying the content of lipid peroxide oxidation products in blood of cows with different types of higher nervous activity are shown in the article. The purpose of the study was to determine the effect of typological features of the nervous system on the content of lipid peroxide oxidation products in bovine blood. The research was carried out on the basis of the farm "Kolos" village Borodyanka, Kyiv region on clinically healthy 2-3rd lactation cows of Ukrainian black-and- white breed. On the basis of the studying the conditioned reflex activity, 4 experimental groups of animals were formed with 4 most typical SHAPE \* MERGEFORMAT Сисюк Ю. О. representatives of certain types of higher nervous activity in each of them: 1st group - strong balanced mobile type, 2nd group - strong balanced inert type, 3rd group - strong unbalanced type, 4th group - weak type. The research material was blood, in which the content of TBC-active products, diene conjugates and lipid hydroperoxides was determined. It has been established that the balance - ɳ<sup>2</sup><sub>х</sub>= 0.39 (P<0.01) and the mobility - ɳ<sup>2</sup><sub>х</sub>= 0.51 (P<0.01) of the cortical processes have a significant influence on the content of diene conjugates in blood plasma of cows with different types of higher nervous activities. The lipid hydroperoxides content in blood plasma of cows with different types of higher nervous activity is significantly influenced by the strength - ɳ<sup>2</sup><sub>х</sub>= 0.35 (P<0.01) and the balance- ɳ<sup>2</sup><sub>х</sub>= 0.39 (P<0.01) of the cortical processes. Instead, the content of TBA-active products in blood plasma of cows withdifferent types of higher nervous activity has a significant impact on the balance of cortical processes - ɳ<sup>2</sup><sub>х</sub>= = 0.24 (P<0.05). Thus, the influence of the main characteristics of cortical processes on the content of lipid peroxide oxidation products in bovine blood has been established. In animals of weak type of higher nervous activity, the content of lipid peroxide oxidation products in blood is higher than in animals of strong types of higher nervous activity.
