| Summary: | The study of stress sensitivity in newborn animals is an urgent problem. According to the type of neurohumoral activity, animals differ from each other. The body’s response to the effects of stress can manifest itself in the form of adaptation or exhaustion. One of the most recognized definitions of the term “disease” is damage to the structure and function of the body under the influence of external factors during the reactive mobilization of its compensatory and adaptive mechanisms. As well as a set of non-specific changes in the body that are the result of its neurohumoral response to external stimuli that are stress. Based on the above, we set the following tasks: to develop a method for detecting stress-dependent animals; to study the effect of stress on the immune system of newborn calves; to study the influence of the Central nervous system on the manifestation of regrouping stress and its correction using sedatives. Experiments to study stress sensitivity were performed on newborn calves. A method was developed for detecting stress sensitivity in newborn calves, according to the formulated formula (know-how). Animals that have u.e according to the formula below 1.35 refers to stress-resistant, and with a value above 1.35-to stress-sensitive. When studying the effect of stress on the immune system, differences in indicators were found depending on stress sensitivity.
