EFFECTIVE APPLICATION OF THE BIOANTIOXIDANT COMPOSITION IN BEEF PRODUCTION

 In the Urals and the Udmurt Republic, the problem of mineral nutrition of animals is especially relevant, as most of the territory belongs to a biogeochemical area that is deficient in a number of trace elements, including such ultramicroelement as selenium. The effect of biologically active substances for improving productivity of beef calves black-motley breed was studied. The studies combined use of antioxidant vitamins, organic form of selenium in the I experimental group, and bioantioxidant complex rich by bioflavonoid – dihydroquercetin in II experimental group contributed to the increase meat productivity of animals against control. In the composition of this complex the activity of each element in neutralizing of free radicals is enhanced by the presence of the others. This prolonged effect of bioantioxidant complex is achieved by a technological method: active agents are turned into oil-in-water emulsion, using natural emulsifiers. Meat productivity of calves of black-motley breed appreciated by the results of the control of slaughter and found that the heaviest carcasses were obtained from calves I and II experimental groups – 234.5 kg (P ≥ 0.999) and 240.2 kg (P ≥ 0.999), respectively, which were higher than in control peers to 5.48–8.05 %. The use of bioantioxidant complexes also contributed to the increase in the yield of internal fat in the carcasses of experimental animals, hence, obtaining meat with a high energy value: the control group – 2.4 %, I experimental group – 2.6 %, II experienced group – 2.8 %, however, revealed statistically significant differences steers. Between-group differences in the weight of the carcass and the internal fat caused unequal level of slaughter mass. Lethal mass in the control group was 232.7 kg, what on 5.76 % lower than in I experimental group and on 8.64 % of II experimental group index.
