Bioenergy estimation of the potential of meat productivity of the lamb of the North Caucasian and Romanovskaya breeds

The research was carried out in LLC "Selkhozinvest" RS Navesnoe, Livensky district, Orel region, and PSF "Adzhiev" RS Podmokrinskoye, Mtsensk district, Orel region, on the number of sheep of the North Caucasian and Romanov breeds. As a result of the research, a linear dependence of the level of the bioelectric potential of the superficially localized biologically active centers (SLBAC) with the indicators of live weight of experienced rams was established. So, animals of the control group of two breeds with a the level of bioelectric potential (LBP) SLBAC differed in lower live weight from the rams in the experimental group by 7.3% (North Caucasian breed) and 5.6% (Romanov breed), with highly significant differences. Carcasses of rams that before slaughter were distinguished by a high LBP SLBAC, in terms of slaughter weight - by 11%, in terms of weight of a pair of carcasses - by 6% (North Caucasian breed) and 8% (Romanov breed), in terms of slaughter yield - by 4% (North Caucasian breed) and 6 % (Romanov breed) exceeded these indicators in control animals, with highly significant differences. The indices of the slaughter characteristics of carcasses also retained the tendency of a direct relationship with the LBP of the SLBAC of the experimental animals. The largest mass of chilled carcasses was noted in the group of animals with a 4.8% higher (North Caucasian breed) and 8.4% (Romanov breed) level of biopotential (LBP) SLBAC, with significant differences relative to control (P function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
