Abstract

The tone of the autonomic nervous system is considered on the one hand as one of the manifestations of homeostasis, and on the other hand, as one of the mechanisms of its regulation. The predominance of the tonic effect of the parasympathetic and sympathetic departments of the autonomic nervous system is defined as vagotonia and sympathicotonia. The tone of the autonomic nervous system in cows was determined using a trigeminal vagal test. According to the results, the animal was classified as normotonic, sympathicotonic or vagotonic. The tone of the autonomic nervous system in cows in summer inversely correlated with copper content in whole blood (r=-0.62; p<0.05) and blood cells (r=-0.58; p<0.05). In winter, the correlation of the tone of the autonomic nervous system in cows with its content in whole blood, serum and blood cells did not reach significant values (r=-0.21–0.36). Increased tone of the parasympathetic department of the autonomic nervous system, regardless of the season, had almost no effect on copper content in serum, whole blood and its cells (ղ²x=0.01–0.23). At the same time, sympathicotonia in summer has a significant impact only on the copper content in blood cells – ղ²x=0.58 (p<0.05), while in winter this effect increased significantly (ղ²x=0.91; p<0.001). The multifactor analysis of variance revealed the dependence of copper content on the tone of the autonomic nervous system and the season. However, the vegetative status of cows had a significant impact on its content only in blood cells (F=8.59>FU=4.41; p<0.01), and the season limited copper content only in whole blood (F=12.12>FU=3.55; p<0.01).
