A biological experiment was conducted to evaluate the ability of glucomannan-containing yeast product (GYP) to adsorb aflatoxin B1 (AFBJ in gut conditions of broiler chickens. Three levels of aflatoxin B1 (0, 250 and 500 meg/Kg) and two levels of GYP (0 1 Kg/ton) were tested on a total of one hundred and twenty uniformly weighing five-week-old commercial broiler chickens. Each group had 5 replicates of 4 birds. From each group four birds were sacrificed at 30 minutes intervals i. e., 0, 30, 60, 90 and 120 minutes and the gut content was collected. The AFB1 concentration in the dried sample was quantified by thin layer chromatography and percent of AFB L recovered was measured. No AFB1 was detected in the gut samples from first two dietary treatments at all the time intervals. In the gut samples ofAFB fontaing diets, there was significant reduction in the percent recovery of AFB1 at different time intervals, may be due to absorption of the toxin into the biological system. There was significant reduction in percent AFBL recovered in the gut samples of GYP treated AFB fontaing diets, may be due to the adsorption of the AFB1 by the GYP or due to the absorption of the AFBL into the biological system.
