Efficacy of Mycotoxin Adsorbents on Aflatoxin B1 Decontamination and in vitro Rumen Fermentation

Abstract

This study was conducted by using an in vitro gas production technique to study the effect of aflatoxinB1 and mycotoxins adsorbents on aflatoxin B1 decontamination and efficiency of rumen fermentation. There were eight treatments, that assigned into completely Randomized Design: T1=the control group, T2= the diet plus 1 µg/mg of aflatoxin B1 (AFB1), T3, T4, T5 = the diets supplement 0.5% of each adsorbent (activated charcoal, montmorillonite, Saccharomyces cerevisiae) and T6, T7, T8 = the diets plus 1 µg/mg of AFB1
together with 0.5% of each mycotoxin adsorbent, respectively. The results were shown that the gas production from the insoluble fraction and the potential extent of gas production in the diet plus the AFB1 were lower than the control (P<0.05). Moreover, montmorillonite and S. cerevisiae were effectively reduced
the negative effect of AFB1 on gas production. In contrast, the diet plus AFB1 and diet plus mycotoxin adsorbents did not interfere the in vitro dry matter and organic matter digestibilities, volatile fatty acids and ammonia nitrogen (P>0.05). In conclusion, AFB1 had effected and had decreased cumulative gas production. However, montmorillonite and S. cerevisiae, as effective adsorbents, could be reduced the adverse effect of AFB1 in this study.
