The dynamics of HRV animals and their correlations with milk yield and age

Abstract

For several years, strengthened state support measures domestic livestock has reached on many qualitative and quantitative indicators of the European level. First of all, we are talking about industrial poultry farming and pig breeding, as well as dairy and beef cattle breeding in terms of increasing the genetic potential. At the same time, the direction of dairy cattle breeding remains one of the most problematic. Annually, purchases of expensive animals experiencing stress during transportation are carried out, which leads to a decrease in the vital energy and functional-physiological reserves of the body. In this regard, many questions arise related to the need to preserve these functional reserves, which can be studied using non-invasive methods. One of such methods is cardiointervalometry of heart rate variability. The method allows to assess the physiological state of the organism of an animal, on which factors, both exogenous and endogenous, can act. The obtained indicators can be used in conducting practical and lecture classes at veterinary faculties of universities, as well as serve as material for further research and discoveries.
