Object - experimental cows, feeding bull-calves, pigs who contained in terrain ІІІ regions of nuclear pollution; the feedstuff cultivated on different background of fertilising of the specified region; fodder rations with incorporation of different minerals-sorbents; milk, meat, an internals, a faecal matter, urine, blood, the cicatricial fluid, received from experimental animals. The purpose - experimentally to prove methods of decrease in transition 137Сs both heavy metals in milk and meat by their production in ІІІ to region of nuclear pollution. Methods - zootechnical, carrying out of scientifically-economic experiences (analysis of feeding of animals, efficiency, feedstuff payment, lethal qualities); physiological (digestion of nutrients, balances of nitrogen, calcium, phosphorus, inorganic substances); chemical (definition of a chemical compound of feedstuff, milk, a muscular tissue and an internals); radiological (specific activity 137Сs in sterns, milk, meat, an internals); Spectrometer (concentration Pb, Cd, Hg, Cu, Zn in sterns, milk and beef); biochemical (research of indicators of a cicatricial metabolism, an uglevodno-fatty exchange at experimental animals); hematological (biochemical and morphological); economic (efficacyy of use of minerals-sorbents and the optimised rations of feeding of animals); statistical (a biometrical analysis of stuffs of researches); analytical (the literature survey, generalisation of results) and industrial approbation. Theoretically also the expediency of use of connatural minerals as sorbents of radioactive nuclides and heavy metals in feeding of agricultural animals is experimentally proved. Injection of different adsorbents in a compound of rations at feeding of animals in region of nuclear pollution raises their biological value, positively influences metabolic processes and efficiency of cows, a feeding joung growth of the large cattle and pigs, negative influence of heavy metals on an organism of people promotes enriching of quality and ecological purity ofreceived milk and meat which allow to lower a dose an atomic irradiation load on the population of a wooded district of region of Ukraine. Migration 137Сs and heavy metals in separate parts of a biological mains circuit in local region a technogenic load is investigated. Positive influence of standard maintenance of animals digestion by a protein, Saccharum and microelements on their efficiency, a resistance of an organism and accumulation decrease 137Сs both heavy metals in milk and meat is established. At the expense of introduction of the offered system of a feeding by an agricultural animal of the most effective connatural minerals-sorbents in economy woodlands of region efficiency of animals has raised on 5,2-7,6 % thanks to what the additional annual profit has compounded 407,0 thousand grn, and concentration of toxics in milk and meat has decreased for 7,4-43,4 %. Use sphere are the agricultural enterprises and the personal peasant farms which have suffered owing to failure on CHAES.
