The efficacy of zearalenone destroyer in feed fortified with different amounts of zearalenone (ZEA) and the impact of the destroyer itself on selected organs of the reproductive tract of gilts was examined. The gilts were divided into five groups: group I (n=8) - non-treated control; group II (n=8) - receiving 200 µ of ZEA/kg b.w.; group III (n=8) - fed feeding stuff with zearalenone destroyer and with 200 µ of ZEA/kg b.w.; group IV (n=8) - fed feeding stuff with zearalenone destroyer and with 150 µ of ZEA/kg b.w.; group V (n=8) - fed feeding stuff with the neutral residues of zearalenone destroyer. After slaughter (day 8), the animals were autopsied and the segments of the uterus, ovaries, uterine tube, vulva, and vagina were examined histopathologically. It was found that the addition of the zearalenone destroyer to feed fortified with zearalenone limits the oestrogenic mode of action of this mycotoxin, and residues of the destroyer have no impact on the structure and functioning of the organs of the reproductive tract.
