Adsorbents are characterized by synergetic effect with a wide range of different biologically active additives, including mold inhibitors that are successfully used to reduce the accumulation of mycotoxins in feed, which positively affect broilers metabolism and biological value of poultry meat. The research aims to study broilers meat productivity and enzymatic activity of enzymes in the gastrointestinal tract when preparations mold inhibitor Mold-Zap and adsorbent Ecosil are introduced into diets with a tolerant level of aflatoxin B1. The experimental material was statistically processed by Student’s t-test using software package SNEDECOR. In the course of the research it was found that in the mixture preparations Mold-Zap at a dose of 1,5 kg/t feed and Ekosil at a dose of 125 g/t feed had the highest stimulating effect on the activity of cellulases, proteinases and amylases in the content of the gizzard stomach and duodenum. The highest stimulating effect on birds’ slaughter indicators had joint supplement of preparations Ecosil and Mold-Zap to mixed feed, which provided for broilers in the third test group weight gain of semi-eviscerated carcass by 14,7% and eviscerated – 13,7%%, as well as slaughter yield – by 1,6%. Broilers of the third test group relative to the control contained 1,04-1,16% and 1,24-1,59% more dry matters and protein in their pectoral and femoris. The joint supplement of preparations Ecosil and Mold-Zap provided for chickens of the third test group the most significant (p>0,95) superiority over the control in the meat biological value by 22,2%.
