Heart research is important in veterinary practice due to insufficient attention to heart disease in cattle at the present stage of development of veterinary medicine. ECG characteristics and heart rate variability were analyzed in 103 Jerseys. To analyze and record the ECG of Jersey cattle, the CONAN-4.5 program was used on the frontal lead-off system according to the method of M. P. Roschevsky. Analysis of heart rate variability (HRV) is a widely used method in medical practice to assess autonomic regulation and the state of the heart. Mathematical analysis of heart rate rhythms to determine the state of the autonomic nervous system is important for the pathogenetic treatment of many diseases. An important place is occupied by the issue of meeting the needs of the population in dairy products. For this reason, the livestock industry is developing rapidly. However, when improving dairy cattle breeding, it is necessary to take into account the physiological capabilities and characteristics of animals at all stages of their ontogenesis. The study of the cardiovascular system is of great importance in veterinary medical and preventive work. With an increase in activity from «vagotania» to «sympathicotonia», milk productivity increases, i.e. activation of the sympathetic autonomic nervous system increases the activity of the hormone oxytocin, which affects the intensity of milk flow. Hypersympathicotonic patients most likely have hyperfunctions of cardiac activity,
there is a decrease in milk production.
