Initial vegetative tonus of cows of the jersey breed based on the stress index and its analysis initial vegetative tonus of cows of the jersey breed based on the stress index and its analysis
The tension index (IN) is the indicator which most fully informs about the degree of tension of compensatory internal mechanisms of the body, and on the functioning of the Central contour of heart rate regulation. Functional reserves be measured using the method of heart rate variability. The index of tension of regulatory systems of an organism reflects the level of centralization of control heart rhythm and indirectly characterizes the state of functional-operational systems. Was removed electrocardiogram in cattle - Jersey breed in the amount of 103 goals. In the course of mathematical calculations were obtained different values of the strain index. On the basis of a stress index calculated at baseline autonomic tone, which was a division of the investigated animals into 4 groups: vagotonics, normotensive, sympathicotonic and gipersimpatikotonii. To confirm the correct allocation of animals to groups using the statistical program was constructed classification matrix. Therefore, the study of indicators of heart rate variability for cows Jersey breed is relevant because at the moment there is no information, allowing to consider peculiarities of this breed of cattle, that would help in the future forecasting milk productivity and duration of the economic use of the studies assessing the functional state of the organism by the method of mathematical analysis of heart rate variability was installed initial vegetative tonus of cows of the Jersey breed.
