ANALYSIS OF INDICATORS OF HEART RATE VARIABILITY OF COWS OF THE JERSEY BREED ^{[№ 11 ' 2017]}
In the course of the study were taken and analyzed in the electrocardiogram cows Jersey breed using the method of R.M. Baevsky (1972). The studies were conducted using the comprehensive laboratory elektrokardiograficheskie CONAN 4.5 developed in the Moscow state University named after M.V. Lomonosov. Researches of indicators of heart rate variability for cows Jersey breed is not currently carried out, taking into account the peculiarities of this breed of cattle and this will help in the future forecasting milk productivity and duration of economic use. After the division of treated animals by strain index in each group was set the baseline autonomic tone. To assess the functional state of the circulatory system are reflected in the study of variational pulsogram. Numeric characteristics of electrocardiograms are fashion (M_o), the amplitude of fashion (AM_o) and variation magnitude (DX). All these primary indicators provide an opportunity to assess which part of the autonomic nervous system predominates in the regulation of cardiac rhythm. Among the economic indicators were studied, the intensity of galactopoiesis. As a result of lactation occur functional physiological changes in the body condition of the animal and a major restructuring of metabolism, which affects this economic indicator. A comparative analysis of the numerical characteristics of the variation pulsogram. When analyzing functional state of the organism, method of mathematical analysis of heart rate variability were obtained and studied of the primary numerical characteristics of the variation pulsogram. On the basis of these data it was established the breed characteristics of cows of the Jersey breed.
