Aflatoxins are metabolites from fungi, that may be injurious to animal health, resulting in reduced production and affecting poultry industry by decrease the growth rate and worsening feed conversion. A study was carried out to evaluate the electrophoresis profile of serum protein in broilers fed with diets containing aflatoxins and natural clinoptilolite clay. A total of 528 male broilers Ross were used, distributed in 6 treatments with 4 replications each: T1 control (without aflatoxins or clinoptilolite), T2 5ppm of aflatoxins, T3 0.25% of clinoptilolite, T4 5ppm of aflatoxins and 0.25% of clinoptilolite, T5 0.5% of clinoptilolite and T6 5ppm of aflatoxins and 0.5% of clinoptilolite. The broilers were placed in 24 boxes and submitted to treatments from 1 to 42 days, when they were slaughtered. Were analyzed the total proteins, albumin fractions, alpha 1, alpha 2, beta and gamma. The aflatoxins decreased (P<0.05) total protein, albumin, and globulins (alpha and beta fractions). However, no effect (P<0.05) of aflatoxins was observed about gamma fraction. The clinoptilolite no modify (P<0.05) the serum proteins. Related to control, broilers fed with diets containing aflatoxins and clinoptilolite presented low (P<0.05) levels of total protein, albumin, and globulins (alpha and beta fractions). In conclusion, aflatoxins change the electrophoresis profile and clinoptilolite is not able to protect against this change
