For several years, strengthened state support caused a situation, when domestic livestock has reached the European level on many qualitative and quantitative parameters. At the same time, dairy cattle breeding remains one of the most problematic branches. Intense loads during economic use lead to a decrease in vital energy and functional and physiological reserves of the body. The problem of reducing the economic characteristics of cows with age is relevant. In this regard, many questions related to the need to preserve these functional reserves arise and the latter can be studied using non-invasive methods. One of such methods is cardiointervalometry of heart rate variability. The method allows evaluating the physiological state of the animal, which can be influenced by both exogenous and endogenous factors.
