THE EVALUTION OF BENTONITE AND ACTIVITED CHARCOAL TO ADSORB T-2 TOXIN FROME ANIMAL DITE

Abstract

Different combinatis on of physical absorbents ,bcntonite and charcoal ,(4:l,3:2,2:3,andl:4) at 5%, to eliminate T2-toxin from liquid medium containing 500mg/l was evaluated. The effect of 3 levels of the combination, (3%Bcntonitc and 2% Charcoal), on body weight variation of mice feed on diet contaminated with 25mg/kg of T2-toxin was tested .Results showed that the 2% (Bentonitc + charcoal) was more efficacy with mean variation in body weight of O.lg after one month of feeding compared to -1.8 g for the control and -5.0 g for the diet containing toxin only .The biochemical characters of the blood of mice feed on physical adsorbent showed improvement. The count of red bloodcells was 2.9 * 1012 I for both treatment 5%(Bcntonite+charcoal) +T2_toxin and 2%(Bentonitc+charcoaI) + T2-toxin compared to 2.3* 10,2 I for the toxin treatment only. Also the white blood cell were increased with adsorbent compared to the toxin treatment only, The count of cells were 24.8, 24.6, 25.0 and 24.1* 10* I for the 2%,3%.5% adsorbents and T2-toxin, rcspcctively.Thc hcamoglobin increased to 8.4 g100 ml for 2%(Bentonite + charcoal) +T2-toxin treatment com parted with 8.0g100ml for toxin treatment only.
