To detoxify heavy metals, adsorbents, which bind heavy metals and other toxins in the poultry digestive tract and remove them from the body without detriment to the digestibility of biologically active substances in the diet, is effectively used. Along with adsorbents, preparations that have synergistic effect and at the same time optimize the composition of micro flora in the digestive tract should be included in poultry diets. The research was aimed to study the effectiveness of using probiotic Lactin and adsorbent Biocoretron in mixed feed based on cereal grain of local production containing the heavy metal excess to increase the broilers productivity and optimize metabolism. The objects of research were broiler chickens of cross Smena-7. The research results were statistically processed by Students t-test using mathematical analysis software package Microsoft Excel. Inclusion of probiotic Lactin in a dose of 2000 g/t and adsorbent Biocoretron in a dose of 1000 g/t feed allowed the chickens of the third test group versus the control to increase significantly (P>0.95) the flock safety by 5,0%, indicators of absolute and average daily weight gain by 12.0%. They also significantly (P>0.95) better digested the diet dry matter by 3.8% organic matter 3.8%, crude protein 4.2%, crude fiber 3.1% and nitrogen-free extractives 4.2%. Broilers of the control group used better (P>0.95) taken with feed nitrogen by 51.73%, and birds in the third test group by 3.38%. Broilers of the third test group showed the highest activity of proteinases, cellulases and amylases in the chymus of the small intestine having significantly (P>0.95) exceeded their control counterparts on these indicators by 13.5, 12.7 and 14.5%.
