The objective of this work was to evaluate the seric mineral concentrations and the hepatic and renal functions of broiler chicken, experimentally intoxicated with 3 ppm of aflatoxin, and submitted to different concentrations of sodic montmorillonite in the diet. In this study 720 Cobb's male broiler chickens were used, which were divided in six treatments: T1, normal diet; T2, diet with aflatoxin (3 ppm); T3, diet with sodic montmorillonite (0.25%); T4, diet with aflatoxin (3 ppm) + sodic montmorillonite (0.25%); T5, diet with sodic montmorillonite (0.50%); T6, diet with aflatoxin (3 ppm) + sodic montmorillonite (0.5%); with six repetitions of each treatment. The diet with 3 ppm of aflatoxin resulted in a significant decrease in serum concentrations of total protein, albumin, globulins and aspartate aminotransferase; there was significant decrease of seric concentration of uric acid in the diet with aflatoxin (3 ppm) + 0.25% sodic montmorillonite; in the diet with aflatoxin + 0.5% sodic montmorillonite there was significant decrease in seric concentrations of phosphorus. Aflatoxin in the diet (3 ppm) causes change in the hepatic function of broiler chickens. The use of 0.5% sodic montmorillonite is effective in preventing the toxic effects of aflatoxins, but causes decrease in phosphorus seric levels.
