Rozputnij O. Transformation of heavy metals in biotechnological systems on beef and pork production

The dissertation is devoted to evaluation of condition of biogene migration of heavy metals at big industrial complexes on pork and beef production, determination of role of organism of young cattle and pigs in bio-transformation of copper, zinc, manganese, cadmium and lead for the period of growing and fattening of animals, and providing the ecological welfare at the zone of functioning biotechnological systems. On the basis of conducted research, the role of individual links (forage, water, animal organism, manure biomass) in biogene migration of heavy metals was defined. Coefficient of biotransformatoin of heavy metals such as copper, zinc, manganese, cadmium, lead from forage and water into an organism of young pigs for the period of growing and fattening are studied. The main part of content of heavy metals of forage and water is not left for a long in an organism of animals and transform into manure biomass. The quntity of animals per 1 ha of agricultural land was defind for utilization their man ure biomass according to content of heavy metals with the purpose of ecological welfare maintenance.
