Abstrakt: The objectives of this study were to evaluate the exposure to a diet naturally contaminated with mycotoxins on lactation performance, animal health, and the ability to sequester agents (SA) to reduce the human exposure to AFM 1 . Sixty healthy lactating Holstein cows were randomly assigned to two groups: naturally contaminated diet without and with the addition of a SA (20 g/cow/d AntitoxCooPil® -60% zeolite-40% cell wall-). Each cow was monitored throughout lactation. The concentration of aflatoxin B 1 (AFB 1 ) in feed and M 1 (AFM 1 ) in milk, health status, and productive and reproductive parameters were measured. AFB 1 concentration in feed was very low (2.31 μg/kgDM). The addition of SA reduced the milk AFM 1 concentrations (0.016 vs. 0.008 μg/kg) and transfer rates (2.19 vs. 0.77%). No differences were observed in health status, production and reproduction performance. The inclusion of SA in the diet of dairy cows reduce the risk in the most susceptible population.
