Abstract :
This experiment was conducted to study the effect of Aflatoxins (AF) on broiler performance, organ weight, plasma characteristics, protein digestibility, and metabolizable energy of the
diets. Dietary treatments were: 1) control diet based on corn and soybean meal; 2, 3 and 4) control
diet plus 1 mg kg-1 AF, 1 mg kg-1 AF and 0.25% mycosorb, and 0.25% Mycosorb, respectively. The
results in the Aflatoxins and Aflatoxins+ mycosorb treatments showed that dietary AF, significantly
decreased the feed intake and weight gain as compared to the control diet (P<0.001). Treatment 2
resulted in inferior feed conversation ratio in comparison to the control diet (p<0.05). Uric acid and
total protein in the second and third, and phosphorous only in the third treatment were significantly
lower than the control (P<0.05). The in-vivo protein and dry matter digestibility, apparent metabolizable energy (AME) and nitrogen corrected-apparent metabolizable energy (AMEn) were not affected
by the treatment (P>0.05). Aflatoxin resulted in the proventriculus enlargement, increased liver
weight and AF deposition in the liver and breast muscle (P<0.05). This study clearly demonstrated
that Mycosorb was effective in alleviating the adverse effects of dietary aflatoxins in broiler chickens.
