DYNAMICS OF ECONOMIC CHARACTERISTICS OF COWS OF JERSEY BREED WITH DIFFERENT TYPES OF VEGETATIVE REGULATION
Recently, in the Russian Federation there has been a development of the agro-industrial complex, namely animal husbandry, which in many qualitative and quantitative indicators has reached the European level. The development of dairy farming remains the most problematic today. It is necessary to search for ways to optimize the physiological state, preserve and develop functional reserves and adaptive abilities of dairy cows as basic factors for increasing their productivity on farms and complexes. It is necessary to use non-invasive methods for studying the functional reserves of the body. There is a method that allows you to get indicators that reflect the functional reserve - cardiointervalometry of heart rate variability. This method allows you to assess the physiological state of the animal. The obtained indicators can be used during practical and lecture classes at the veterinary faculties of universities, as well as serve as material for further research and discoveries.
