Abstract

Conducted studies have shown that the content of sodium in the whole blood of cows, depending on the type of higher nervous activity, was 2.5–2.9 g/l. In cows of a strong balanced inert and strong unbalanced type of higher nervous activity the metal content was, respectively, 2.3% (р < 0.01) and 4.6% (р < 0.01) higher than in cows of a strong balanced mobile type. At the same time, in cows of a weak type of higher nervous activity, the sodium content was higher compared to cows with a strong, balanced, mobile type, the content of this metal in blood serum did not differ reliably regardless of the season. The sodium content in blood cells depends on the type of higher nervous activity regardless of the season. According to the results of the studies, the potassium content in whole blood depending on the type of higher nervous activity and the season, was 114–168 mg/100 ml and differed reliably in animals that had different types of higher nervous activity. In the blood serum of cows, the content of total phosphorus was 11.9–14.0 mg/100 ml, but did not exceed physiological values and did not differ reliably in cows with different types of higher nervous activity. The season has a significant effect on the phosphorus content in whole blood and its serum only in cows of a strong unbalanced type of higher nervous activity. It was noted that in animals with different types of higher nervous activity, the calcium content in different blood fractions did not exceed physiological limits. The strength, balance and mobility of nervous processes at different times of the year are not related to the calcium content in whole blood and serum. It should be noted that in summer the main characteristics of nervous processes are inversely related to the content of calcium in blood cells (r = -0.53–0.57; p < 0.05). Thus in winter these correlations are unreliable (r =-0.32–0.48). Therefore, the dependence between the type of higher nervous activity and the content of macroelements and the relationship between the main characteristics of nervous processes in cows were established on the basis of the conducted studies
