Among mycotoxins, aflatoxins produced by microscopic fungi Aspergillus flavus and parasiticus stand out for their toxic properties. When the most widely distributed aflatoxin B1 is ingested into the dairy cows diet with milk its metabolite aflatoxin M1 can be extracted. Preparations of chelated nature are increasingly used as detoxicants of mycotoxins. The research aims to study the effect of chelate preparation complexon as a part of diets with high content of aflatoxin B1, the concentrates basis of which were corn, barley and soybean, on some indicators of intermediate metabolism and productivity in lactating cows. The experimental material was statistically processed by Students t-test using application programs software package SNEDECOR. In the course studies application of chelate preparation complexon at a dose of 0,2% by feed weight showed that in the cows milk of the test group the fat content was higher by 0.23% and the protein by 0.19% than in the control. Complexon supplements to the animals diets in the test group contributed versus the control to decrease aflatoxin M1 in their products by 2.09 times. The preparation complexon had a positive effect on the hematopoietic function of the cows body in the test group, thereby versus the control, their blood contained more red blood cells by 24.4% and hemoglobin by 20.2%. The level of aflatoxin B1 detoxification in experimental animals body was closely related to the synthesis of ascorbic acid and retinol in the liver from carotene of feeds. Due to this, cows in the test group had a higher concentration of vitamins A and C in their blood serum, having surpassed the control in these indicators by 2.93 and 2.11 times. According to the content of γ-globulins in the blood serum, animals of the test group exceeded the control by 0.23 mg%, which indicates a favorable effect of the preparation complexon on the cows body resistance.
