Abstract
For the first time on the basis of complex researches the zootechnical fea-sibility of application of the developed biological products Prevention-N-A and Prevention-N-E in the production technology of beef for realization of bioresource potential of meat qualities of bull-calves of black and motley breed is evidence-based and experimentally proved. Against the background of application of biological products 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. The high quality of meat hulks on organoleptic, biochemical and spectrometer indicators and, therefore, safety of examinees of preparation is proved. It is established what realization of bioresource potential of an organism of bull-calves has been caused by activization of a hematopoiesis, cellular and humoral factors of nonspecific stability biological products, at more expressed corresponding effect Prevention-N-A.
