Adaptogenes activization and realization of productive qualities Aberdeen-angus

Abstract

Regularities of formation of protective and adaptive functions of an organism of the import meat cattle in the conditions of the Nizhny Novgorod Region on morphological and biochemical blood profiles, to cellular and humoral factors of a nonspecific rezistent are disclosed. It is established that immunoprevention of an organism of bull-calves biological products of PS-6 and Prevention-N-E realizes their bioresource potential of meat efficiency. Against the background of use of medicines the prelethal mass of bull-calves increased by 15,4 and 22,0 kg, lethal weight - by 13,8 and 17,5 kg and the mass of pair ink - by 9,9 and 19,6 kg. The mass of pulp of bull-calves of the 1st and 2nd skilled groups was higher in comparison with control on 8,0 and 15,6 kg, fat - on 0,9 and 0,7 kg, than bones - on 1,3 and 2,4 kg respectively (Р<0,01). The big mass of carcasses of bull-calves of skilled groups has defined also high exits of the most valuable junctures -back chest, lumbar and coxofemoral, for 1,9 and 2,2%, for 0,2 and 0,3%, for 0,2 and 0,8% respectively, than in control. The largest content of pulp of the premium characterized carcasses of bull-calves of the 1st and 2nd skilled groups respectively on 3,2 and 5,7 kg in comparison with control. The high quality of beef on organoleptic, biochemical and spectrometer indicators is proved.
