Abstract
In animals with different types of higher nervous activity (HNA), the ratio of total calcium to inorganic phosphorus in blood serum stayed within the physiological limits and was 1.6–2.0 r. u. Despite of the season, the index in cows of weak type of HNA was 6.3–13.3% (p <0.05) higher than in SBM type of cows. Compared to cows with SBM, SBI and SU type of HNA the total calcium to inorganic phosphorus ratio in blood serum was not significantly different regardless of season. In cows with SU and a weak type of HNA, in winter this index in the serum of blood was higher by 17.3% (p<0.001) and 14.9% (p<0.05) than in warm season. Whereas in cows with balanced types of HNA (SBM and SBI), only the corresponding trend was observed in the range of 8–13%. Therefore, the strength of nervous processes more significantly limited the calcium-phosphorus ratio in the blood serum of cows in summer, whereas the balance – in cold season. Movement of nervous processes in cows does not significantly influence on the calcium-phosphorus ratio in the serum of cows. It was found that the strength of the nervous processes both in summer and winter was inversely related to the calcium-phosphorus ratio in the blood (r = -0.51–0.58; p<0.05-0.01). Nervous process balance is inversely related to the calcium-phosphorus ratio in winter (r = -0.52; p<0.05), whereas in summer this is insignificant (r = -0.29). Movement of nerve processes, despite of the season, is not connected with the indicator of calcium-phosphorus ratio in the blood of cows (r=-0.08–0.29). The formation of the calcium-phosphorus ratio in the blood of cows and main characteristics of nervous processes is determined by regression analysis. The coefficient of determination of the strength of nerve processes to the calcium-phosphorus ratio in whole blood of cows indicates that in summer up to 26% (p<0.05) and in winter up to 33% (p<0.05) variations can be determined by the strength of the nervous processes. Therefore, accurate connectivity and substantial influence of the main characteristics of cortical nerve processes and seasons on the calcium and phosphorus content in the blood of cows have been confirmed.

Summary
Вплив нервових процесів на кальцієво-фосфорне відношення в крові корів у різні пори року. У корів з СВР, СВІ та СН типом ВНД відношення загального Кальцію до неорганічного Фосфору в сироватці крові незалежно від пори року достовірно не відрізняється. Сила нервових процесів у більшій мірі лімітує Кальцієво-Фосфорне відношення в сироватці крові корів влітку, тоді, як врівноваженість – у холодну пору року. Мета роботи ‒ з’ясувати ступінь та характер тварин супроводжується розвитком у них стресового впливу нервових процесів на Кальцієво-Фосфорне стану, що негативно впливає як на їх продуктивність, відношення в крові корів у різні пори року, так і резистентність (Kushch, 2016). Відношення у крові корів з різними типами вищої питанням вивчення індивідуальних особливостей нервової діяльності залежно від пори року.
