Abstract
The article presents the results of a study of the leukocyte composition dependence of the blood of cows of red-motley breed on their ability to acclimatize. Getting into new climatic conditions, animals undergo profound physiological changes. Acclimatization is one of the stress factors for cows. Determination of the presence of stress in cattle can be determined by establishing the dependence of the leukocyte composition of the blood of cows on their ability to adapt. On this basis, it is possible to carry out productive work to reduce the impact of stress on the animal’s body. In the process of research, hematological parameters were studied in dynamics in two groups of animals in the joint-stock company “Luch” in the Ivanovo district of the Amur region. The control group consisted of local cows of the red-motley breed, which are already adapted to the living conditions. An experimental group is a livestock imported from the Krasnoyarsk Territory. The change in blood leukogram indicators from the degree of acclimatization of cattle of the Red-motley breed was reliably established. The obtained research results confirm the possibility of analyzing the degree of adaptation of animals using a comparative analysis of leukograms of imported and local cattle. The results can be the basis for the development of methods for determining the degree of acclimatization and stress in animals. The technique is necessary for research aimed at developing ways and tools to reduce the effects of stress and combat its negative impact on the animal’s body. Farm specialists, in the presence of a control group not subject to stress, carried out the study under production conditions.
