Prevention series biopreparations in realization of meat qualities of bull-calves of black and motley breed

The conceptual provisions significantly adding the modern database new scientific data on a possibility of completer implementation of meat qualities of bull-calves of black and motley breed immunoprevention of an organism biopreparations are received. Prevention series biopreparations, a method and the diagram of their application in the production technology of beef in dairy cattle breeding are developed. The economic efficiency and prospects of use of biopreparations of the Prevention series in the production technology of beef for implementation of bioresource potential of meat qualities of bull-calves of black and motley breed is proved. Against the background of application of biological preparations activization of growth and development of bull-calves during the periods of cultivation, growing and sagination is established that has caused higher lethal and meat qualities of hulks and, as a result, an exit of valuable junctures: spinnermodel - on 6,1 and 4,0 kg (Р
