This experiment was conducted to determine the ability of activated sodium bentonite(ASB) at a concentration of 0.5% to reduce the toxicity of aflatoxins (AF) at 2.5 mg or T-2 toxin at 4 mg/kg of feeds alone or in combination on one–day-old male broiler chicks feed for three weeks. Results indicated the BW gain was reduced significantly (p<0.05) when feeds containing AF or T2 and AF with T-2 toxin to 26.17, 18.88 and 37.38% respectively, and become 17.4, 14 and 30.81% respectively changed from control group when adding ASB. The decreased feed consumption , efficiency feed utilization , the increased relative (liver, kidney, heart, spleen, pancreas, gizzard) proventiculus weights , decreased relative bursal of fabricious , thymus gland weights , increased in the total leucocytes counts , absolute numbers of heterophils , decreased the lymphocyte, monocyte and basophiles were significantly diminished to different degrees by the sorbent in the feed containing AF alone or with T-2 toxin, while the T-2 toxin group was not affected except increased the relative gizzard weight and decreased relative bursal of Fabricious and thymus gland weights and decreased in total leucocytes counts. The adding ASB did not diminish the toxic effects of T-2 toxin on these parameters.
