AGE-RELATED CHANGES OF THE INITIAL AUTONOMIC TONE IN 2- AND 6-MONTH CALVES
The article reflects the study of the initial autonomic tone with the heart rate variability method of calves of different ages, taking into account the features of age-related changes in the formation of regulatory centers. The presented research methods have high diagnostic efficiency. The results obtained make it possible to identify higher parameters of the integral indicator of the stress index at an early stage. Such a method allows for a preliminary prediction of the cattle productivity, which ensures the effective agricultural use of animals.
