Kurkina S. The migration of heavy metals in biotechnological system on broiler production

The dissertation is devoted to evaluation of condition of biogene migration of heavy metals at big industry battery farm on brioler meet production, determination of the role of organism of hens in biotransformation of copper, zinc, manganese, cadmium and lead for the period of growing of birds. On the basis of conducted research, the role of individual links (rationed mixed fodders, water, bird organism, manure) in biogene migration of heavy metals. Coefficient of biotransformation of heavy metals from mixed fodders and water into an organism of broilers for the period of growing were determined.It was proved, that the mixxed fodders are the main source of reception of heavy metals into bird's organism. Quantity of birds per 1 ha of agricultural land was defined, for the utilization their manure biomass according to content of heavy metals with the purpose of ecological welfare.
