Deoxynivalenol (DON) and zearalenone (ZEN) are mainly contaminated mycotoxins in feeds. The study was carried out to analyze and survey the contamination of DON and ZEN in one hundred thirteen samples of feeds. After cleaning all samples with immunoaffinity column, the mycotoxins were analysed by using high performance liquid chromatography/fluorescence with diode array detector (HPLC /FLD with DAD). The average recoveries of DON were 88.76 and 95.40% at the levels of 200 and 1,000 μg/kg and 87.09 and 98.40% of ZEN were recovered at the levels of 100 and 500 μg/kg, respectively. The limit of detection (LOD) were 6.0 and 3.0 μg/kg for DON and ZEN, respectively. The average concentrations of DON were 372.1, 324.0 and 990.9 μg/kg in chicken, pig and cattle feed, respectively. Those of ZEN were 76.1, 43.7 and 196.2 μg/kg for them, individually.
