Biochemical features of the influence of distribution and accumulation of heavy metals in the system “soil – plant food – poultry droppings” on the organism of broilers

Abstract

The direct consequences of a complex of structural changes in the form of intensification, industrialization and geographic conditioning of heavy metals that can be utilized through soil destruction often lead to environmental problems and cyclically affect the food chain. In this regard, one of the most important areas of research in the field of poultry farming with the identification of chemical waste is the protection of environmental objects, namely the soil as an object characterized by the accumulative properties of heavy metals, which entail a number of consequences. The normal vital activity of a living organism requires an optimal amount of minerals with trace elements and heavy metals, which creates the need to monitor this cyclic system. The paper presents the results of a study of heavy metals from soil samples, samples of plant food, as well as poultry dung and the effect of their excess or deficiency on the biochemical parameters of the body of chickens. Pursuing the relevance of the content of heavy metals in objects eliminated by the body in the form of excrement, containing substances permeable to the entire body, today it is undergoing intensive study, since plant zones are an integral part of the food chain, accompanied by immuno-biochemical significance for the healthy state and development of birds.
