Protective effects of dietary supplementation of Bacillus Subtilis MZ18 against the reproductive toxicity of zearalenone in pregnant rats.

The microbial detoxification method demonstrates significant potential for detoxifying feed contaminated with mycotoxins, but the application of degrading bacteria in mammals was rarely investigated. In this study, the effects of dietary zearalenone on the growth performance, reproductive performance, reproductive organs, hormone levels of rats and the toxicity alleviation of Bacillus subtilis MZ18 were studied. From gestation day 0-20, pregnant SD rats received either a normal diet or a diet supplemented with zearalenone at a dose of 20 mg/kg⋅BW, and with or without supplementation of Bacillus subtilis MZ18 culture.
