Mycotoxins often contaminate cattle food, which can cause liver damage, immunosuppression, and reduced milk production. Although previous studies have shown the benefits of adsorbents in farm animals, knowledge regarding their mechanism of action is limited, especially when intoxication occurs due to naturally contaminated diets. The present study aimed to assess whether the daily oral administration of mycotoxin adsorbent bentonite clay based on aluminosilicate for 56 days, would attenuate these changes in 18 dairy cows, which were multiparous in the middle of the lactation stage, and were consuming a diet containing fumonisin B1 and B2, zearalenone, and desoxynivalenol. The animals were divided into treatment (TG, n = 9) and control (CG, n = 9) groups, and subjected to assessment of liver functions, hematological assessments, assessment of oxidative leucocyte metabolism by the tetrazolium nitroazul (NBT) technique, and physical chemical analysis of milk, every week for two months, totaling eight analyses. It was observed that the use of the adsorbent caused a reduction in the milk excretion of aflatoxin M1 (AFM1), an increase in levels of serum protein (p = 0.03) and albumin (p = 0.0001), an increase in leukocyte oxidative metabolism from day 24 of treatment(p = 0.05), and increased milk production from the day 16 of treatment (p = 0.08). There was no improvement in the physicochemical indices of the milk. It was concluded that the use of an aluminosilicate-based adsorbent was able to attenuate the effects of mycotoxins on the function of leukocytes and increase milk production.
