Aflatoxins are a major problem in poultry production and are significant economic and public health burdens worldwide. Three commercial mycotoxin binders (TXB) were used to determine their efficacy in preventing the toxic effects of Aflatoxin B1 (AFB1) on broiler productivity, biochemical and hematological parameters, and liver function. A total of 600 day-old broilers were randomly allotted to 12 treatments in a 3 × 4 factorial arrangement with 3 levels of AFB1 (0, 2, and 4 µg/g) and 4 TXB (no toxin binder, 1.0 g/kg Mycosorb, 1.0 g/kg Formycin, and 20.0 g/kg Anzymit) with 5 replicates of 10 chicks each per treatment. Results indicated that AFB1, in comparison with the control, caused a significant decrease in feed intake, weight gain, feed efficiency, and hematological values. Serum proteins (globulin, albumin, and total protein) and serum Ca and P concentrations followed the same pattern. Relative weights of the heart, gizzard and liver, and AST activity in serum were increased in a dose-dependent manner, but ALT activity was not statistically affected by AFB1. Adding TXB to the AFB1 contaminated diet increased weight gain, feed efficiency, hematological values and serum proteins. The commercial mycotoxin binders decreased AST and ALT activities, but did not have a significant effect on the relative organs weight and serum Ca and P concentrations. Neither AFB1 nor commercial toxin binders affected total cholesterol, LDL, or HDL in this study. It was concluded that the addition of the commercial toxin binders to the AFB1 containing diets reduced the adverse effects of AFB1 and could be helpful as a solution to the aflatoxicosis problem in young broiler chicks.
