The territory of the Republic of North Ossetia -- Alania is one of the most heavy metal contaminated regions in the Russian Federation, due to the number of large non-ferrous metallurgy enterprises in Vladikavkaz. The research is aimed at studying the effect of enzyme preparation Celloviridin G20x and adsorbent Toxfin supplements in the fattening steers' diets containing an increased heavy metal level on their bio-productive indicators. During the experiment, 40 six month-old Simmental steers were selected, which by the analogue scale were divided into 4 groups of 10 heads each. The experiment lasted 12 months. The resulting digital material was processed statistically using the Excel information program. The research results showed that the best productive and physiological effect was obtained when joint feeding these feed additives. Thus, when joint feeding preparations Celloviridin G20x at a dose of 70 g/t and Toxfin at a dose of 1 kg/t mixed feed, the third test group had a significant increase in the average daily live weight gain and the energy and digestible protein to product conversion. When joint feeding these preparations as part of the diet with an increased content of zinc, lead and cadmium, there was an increase in the breakdown of feeds protein, cellulose and easily soluble carbohydrates. Due to this, the animals of the third test group significantly (P<0.05) exceeded their control counterparts in the digestibility coefficients of dry matter, organic matter, crude protein, crude fiber, and nitrogen free extractives. In the process of heavy metal detox by joint feeding preparations Celloviridin G20x and Toxfin the counterparts in the third test group vs. the control for a day deposited more nitrogen in the body.
