FORMATION OF INDICATORS OF MEAT PRODUCTIVITY OF RABBITS WHEN USING THE PROBIOTIC FEED ADDITIVE "AMILOCIN" IN THE DIET
Probiotic feed additive "Amilocin", includes a mixture of bacterial biomass of strains Bacillus subtilis OZ-2 VKPM-11966 (Deposit VKPM from 09.04.2014) and Bacillus amyloliquefaciens OZ-3 VKMP-11967 (Deposit VKPM from 09.04.2014) in equal ratios of 1:1, in spore form with their total amount of at least 3.6×10 ⁹ spores/g. In the experiment, when introduced into the diet of young rabbits with drinking water at a concentration of 0.05 to 0.1%, its positive effect on the formation of meat productivity of experimental animals was established. At slaughter, the increase for the accounting period (from beating to 100-day-old age) was in groups: in the I-control-1969, in the II-2251, III-2357, IV-2284. An increase in live weight in the I-control group was recorded in 3.93; in the II-in 4.28; in the III- in 4.53 and in the IV- in 4.28 times. By weight of the cooled carcass, the significant excess of the experimental groups in relation to the control group was: in group II, 18.9%, in group III-20.2%, in group IV-18.9%. This had a positive effect on the slaughter yield (from 50.8% in the control group to 53.2% - 54.2% in the experimental group). Varietal cutting and deboning of carcasses confirmed the advantage of the experimental groups in comparison with the control, both in terms of muscle mass and meat-bone ratio.
