SELECTED INDICATORS OF BLOOD CELLS OF ANIMALS IN THE CONDITIONS OF A TECHNOGENIC AGROECOSYSTEM

Abstract

The relevance of our research lies in the study of the adaptive functions of the organism of animals
under the conditions of the biogeochemical province of the Southern Urals on the basis of the study of some
of their individual cell components. The research was carried out on the basis of agricultural cooperatives of
the Kartala region, the Chelyabinsk region and in the interdepartmental laboratory of the SUSAU, where a
number of indicators were studied. The first step in cow research was the study of immunological
parameters. After counting and analyzing granulocytes and agranulocytes in peripheral blood, we noted
significant changes in their percentage. First of all, this can say that the state of phagocytic cells directly
affects the formation of immunological deficiency. Eosinophils were also affected by serious changes, their
content in the leukogram is much lower than the comparative indicators. So the content in the 1st and 2nd
groups is 2.3 ± 0.02 and 3.1 ± 0.09, respectively, which is below the norm by 71.25 and 61.25%. As known, it
is eosinophils that are involved in oxidative processes and tissue regeneration processes, as well as transfer
the decay products of proteins with antigenic properties to detoxifying organs. It is necessary to assume the
presence of certain immunopathological reactions in the body of cows and the possible breakdown of
compensatory mechanisms in chronic intoxication with salts of heavy metals. This assumption has caused
the need to study the functional characteristics of immunocompetent cells.
Key words: granulocytes, agranulocytes, adaptation, biopathogenic zone, leukogram.
