The research aims to study broilers meat productivity and enzymatic activity of enzymes in the gastrointestinal tract when preparations mold inhibitor Myсo Сurb at a dose of 1 kg/t feed + adsorbent ALNI-SORB at a dose of 2 kg /t feed are introduced into diets with a tolerant level of aflatoxin B 1 . The object of research was broilers of cross «Smena-8», which at day old by the analogue scale were divided into 4 groups of 100 birds each. The period of growing chickens lasted 42 days. As established in the course of the experiment, due to the combined feeding of preparations of a mold inhibitor and an adsorbent in broilers of the Test 3 group relative to poultry of the control group, a statistically significant increase in the activity of enzymes of proteinases, cellulases and amylases in the muscular stomach and duodenum was observed. These data indicate an improvement in digestion processes under the influence of these drugs due to better detoxification of aflatoxins. The best influence on the slaughter performance and consumer properties of poultry meat from Test group 3 was provided by joint additives of tested preparations, which manifested itself against the control in a significant (P> 0.95). ) an increase in the carcass weight of a half-carcass by 14.7% and gutted -by 13.7%, a slaughter yield by 1.6%, as well as an increase in the mass fraction of dry matter, proteins and an indicator of the biological value of meat in the samples of the pectoral and femoral muscles.
