The aim of the present study was to evaluate the digestibility coefficient of dry matter (DCCM) and crude protein (DCCP) of broilers fed diets containing aflatoxin B1 (AFB1) supplemented with mycotoxin binder (Mycosorb). A total of 200 day old chick (male, Lohmann) with the initial body weight of 42 g/bird were randomly distributed to 20 pens (10 birds/pen). The experiment was designed using a 2x2 factorial completely randomized design with the first main factor being the level of aflatoxin (<0.28 ppb and 2.58 ppb), and the second main factor being mycotoxin binder (with and without). Thus, there were four treatment combinations. The AFB1 diet (2.58 ppb) was formulated by replacing the proportion of fresh corn with the AFB1 corn. The results shows that level of AFB1, mycosotoxin binder and combination between AFB1 and mycotoxin binder did not affect (p>0.05) the digestibility coefficient of dry matter and crude protein of broiler diets. In conclusion, low AFB1 aflatoxin levels of 0.28 ppb and high AFB1 of 2.58 ppb did not decrease the coefficient of crude protein digestiility and dry material of broiler chickens during the 28 days of research. Statistically, added or not added Mycosorb in the ration had no effect on the coefficient of digestibility of coarse proteins and dry ingredients of broiler chickens during the 28 days of research. The combination of AFB1 X Mycosorb in rations did not increase the coefficient of crude protein digestibility nor the digestibility of dry ingredients of broiler chickens during the 28 days of research.
