The present article is concerning with the research of influence of new mineral additive «Koretron» in diets for young pigs on meat performance. The mineral additive «Koretron» adsorbs and removes mycotoxins from the body and is the source of water-soluble silicon, which is necessary for stable functioning of intestine and stomach smooth muscles and for improving of calcium digestibility. It is proved, that the considered feed additive has positive effect for animal growth intensity because it has contributed to increasing of both total and relative weight gain of young pigs on fattening. It is determined, that the mineral additive «Koretron» has positive influence on meat productivity of animals from the test group: killing-out percent, hot carcass weight, rib-eye area as well as weight and meat yield, fleshing index have been increased. The considered mineral additive has contributed to improving of chemical composition of meat: the content of dry matter both in the average meat sample and in the longissimus dorsi, content of nutrients synthesized in carcass meat, energy value of carcass meat, biological value of meat have been increased. The data received during our test give evidence of high bioavailability of water soluble silicon in tested additive, which has activated metabolic processes in the bodies of young pigs on fattening and, as a consequence, the gain of their live weight has been increased and morphological structure of carcasses and meat quality have been improved

Vitamin E, having an antioxidant effect, also has a versatile effect on metabolism. It is proved that vitamin E is necessary for the integrity and optimal function of the reproductive, muscle, circulatory, nervous and immune systems. The feed additive Innovit E 60 was produced in the Russian Federation by the MEGAMIX company using innovative technology, which has no analogues in the world. The article presents the test results of the Innovit E 60 feed additive as a part of premixes for the purpose of enriching compound feeds for broiler chickens with vitamin E. The authors have found that the studied feed additive activated metabolic processes in the body of broiler chickens of ROSS 308 cross. Chickens of the experimental group better digested nutrients feed in comparison with analogues of the control group. A significant increase in the digestibility of crude protein by chickens of the experimental groups was found to be 1.11 and 0.92%, crude fat - by 2.11 and 1.85%, BEV - by 2.53 and 2.24%. The deposition of nitrogen in the body of the chickens of the experimental groups is higher than in the control group by 5.73 and 5.05%, and its use from the accepted - by 2.94 and 2.56%. By the end of the feeding, the difference in live weight was 90.3 (4.25%) and 68.5 g (3.22%), and feed costs per 1 kg of live weight gain decreased by 0.06 and 0.04 kg. The control slaughter of broiler chickens showed that the slaughter yield in the experimental groups increased: males by 0.6 and 0.4%, chickens by 0.8 and 0.5%; the mass of pectoral muscles of males - by 46.0 and 41.0g, chickens - by 43.0 and 36.0g. The feed additive Innovit E 60 in the diets of broiler chickens helps to improve the digestibility of the main nutrients of the feed, increase live weight, slaughter exit and exit of the pectoral muscles
