The study of the interaction of the organism of highly productive animals and the environment in the conditions of biogeochemical provinces, nutrition features, the formation of the diet, the assessment of the elemental status and the study of adaptation. Features of the formation of productivity in areas with increased technogenic pollution with the control of the content of toxic elements in the body of animals. Non-invasive study of metabolism, specific and intraspecific features of the elemental status. Application of the technology for lifetime diagnostics of the physiological state and functional reserves of highly productive animals.
