In the study, in the conditions of the dairy complex of the agricultural Firm Tetyushskoe in the Ulyanovsk region, five groups of cows (26 heads per group) were fed according to detailed standards. Cows of groups II, III, IV and V were fed a new sorption-probiotic Supplement (SPD) Biopinnular at a dose of 0.25; 0.50; 0.75 and 1.00 % of dry matter. SPD was made from the natural mineral diatomite (sorbent) and probiotic microbiota (Bacillus subtilius). Such a formulation reduces impact on the body of endo- and exotoxins, in the digestive tract inhibits the development of pathogenic and stimulates the proliferation of lactic acid bacteria and bifidobacteria, enhances the digestibility and assimilation of nutrients, for exceeds efficiency and productivity of cows, improve the sustainability of milk and its products. On 100 EKE fed, 7.88, 12.54, 3.73 and 3.48 % more milk was obtained from cows of the experimental groups than from control cows (63.86 kg). The highest efficiency of the diet was observed in group III. The SPD corrects the environmental friendliness of milk and its processing products. The concentration of Pb and Cd in them did not exceed the MPC and was dependent on the dose of the fed Supplement. The least effective dose for reducing ecotoxicants in products was 0.25 %. Therefore, to increase the efficiency of the diet and reduce ecotoxicants content in dairy products, it is advisable to use SPD in diets at a dose of 0.50 % of dry matter.
