Increase in meat efficiency of bull-calves new domestic biological preparations

Abstract

For the first time on the basis of complex studies the zooveterinary expediency of the developed biological preparations Prevention-N-A and Prevention-N-E in beef production technology for the realization of bioresource potential of meat qualities of Black Motley bull-calves was scientifically and experimentally proved. Activation of the growth and development of bull-calves in the periods of growth, rearing and fattening was established against the background of biopreparations, which resulted in higher slaughter and meat qualities of the carcasses and, as a consequence, in a higher yield of valuable cuts. The high quality of meat carcasses by organoleptic, biochemical and spectrometric indicators and, consequently, the safety of the tested preparations was proved. It was found that biological preparations lead to the realization of bioresource potential of the organism due to activation of haemopoiesis, cellular and humoral factors of nonspecific resistance.
