Description
Summary:The article discusses the issues of mathematical modeling and processing of cardiointervalogramms of cows with different vegetative regulation. An analysis of the sinus rhythm with subsequent mathematical processing of statistical parameters is presented. The work examines the variational pulsograms of an experimental group of animals, using correlation rhythmography, analyzes the scattergrams, autocorrelation clouds in cows with different levels of vegetative regulation. Studies of heart rate variability indicators for Jersey breed cows are relevant. This is a unique method that allows one to take into account the breed characteristics of cattle, predict milk productivity and increase the period of economic use. The stress index is an indicator that most fully informs about the degree of tension of the body's compensatory mechanisms, as well as about the level of functioning of the central circuit of the regulation of heart rhythm. Based on the stress index, the initial vegetative tone was calculated.
