Abstract. We evaluated the influence of biologically active preparations on the productive indicators of broiler chickens. At the broiler enterprise, we formed one control and 4 test groups of Hubbard ISA F-15 cross chickens with 50 birds in each group. The chickens were kept under floor conditions. The birds from the control group received the main diet; the animals from the first test group, in addition, received Sib-MOS plus concentrate (1.5 kg/t of feed); the birds from the second test group received Sanocid fodder additive (5 kg/t of feed); the birds from the third test group received Zoovestin probiotic preparation (0.2 mL/kg of live weight per day); the birds from the fourth test group received Zoovestin (0.2 mL/kg of live weight per day) and Sanocid (5 kg/t of feed). By the end of the experiment, the live weight of chickens in the control group was 1,813 g; the live weight of chickens from the first group was more than in the control group by 23.4%; from the second group – by 21.4%, from the third group – by 13.9%; from the fourth group – by 1.4%. The absolute increase in live weight in the experimental groups exceeded the value of this indicator in the control group (1773.6 g) by 1.4–24.0%; the average daily increase in live weight in test groups exceeded the control by 0.78–23.3% (in the control, it amounted to 42.48 g). The relative increase in live weight in the experimental groups was at the control level. The feed consumption per bird in all groups was 3.692–3.732 g. The feed consumption per 1 kg of weight increase in the control group was 2.09 kg; in the experimental groups, it was 1.9–19.6% lower. Livability in all the groups was at the level of 100%. The European index of productivity in the control group was 216.87, in the experimental groups, it was higher by 3.3–53.6%. The best results were observed in chickens receiving Sib-Mos plus preparation.
