Abstract. The use of adsorbents in the diet of farm animals and poultry is the most acceptable method for reducing the negative impact of mycotoxin contamination of the grain components of the diet and their effect on the physiological status of the organism. The inclusion in the diet of broiler chickens Elitox in a dose of 0.13 % and Probitox — 0.10 % of the weight of feed allowed to increase the average daily increase in live weight of birds during the period of its growth by 5.2 and 6.5 %, and the safety of the livestock — on 4.0 %. At the same time in the body of broilers received adsorbent throughout the growing period there is an intensive metabolism: the total protein content in the blood serum increased by 1.9–8.5 %, total lipids — by 2.3–4.0, glu- cose — by 14.5–18.4 %, urea decreased by 13.8–19.3 %. The most pronounced erythropoietic effect is noted in the blood of a bird with the addition of Probitox. The Elitox cortex supplement allowed to increase the carcass yield by 1.10 %, Probitox — by 1.42 %, and the muscle tissue content in it increased correspondingly — by 9.3 and 11.2 %, internal fat — by 8.2 and 7.8 %, skin with subcutaneous fat — by 9.3 and 11.8 %. The yield of edible parts of the carcass of broiler chickens of the group with Elitox supplement in comparison with the control one was 6.3 % higher, Probitox received 10.6 %, meat and bone index — 0.13–0.14. The use of the Elitox adsorbent allowed reducing feed costs per unit of growth of live weight by 6.73–7.56 %, while using Probitox — by 6.88–7.70 %. According to zootechnical and economic indicators, Probitox can replace the import additive Elitox in the diet when broiler chickens are grown.
