【摘要】 针对1 655个检测样品,通过酶联试剂盒初筛和液相色谱法验证两种形式进行饲料产品中黄曲霉毒素B1污染状况调查。黄曲霉毒素B1在雏禽配合饲料和蛋禽配合饲料中超标最严重,超标率分别为11.0%和14.0%。饲料产品中黄曲霉毒素B1污染在不同地区中存在较大差异,华中地区蛋禽配合饲料超标率达到34.1%,而华北和东北地区的蛋禽配合料超标率为0。不同规模的企业饲料产品受黄曲霉毒素B1污染程度同样存在差异,中小企业的超标率明显高于大企业。更多还原

【Abstract】 The aflatoxin B1 pollution status survey was studied in feedstuffs,a total of 1 655 samples were detected by ELISA initial detection and HPLC method to validation.The aflatoxin B1 in chicken feed and laying hens compound feed exceeded the target value most serious,exceeding standard rate of 11.0% and 14.0%,respectively.There was a big difference between the AFB1 pollution in different regions,in central China the exceeding standard rate was 34.1%in laying hens compound feed,but in north and northeast regions the exceeding standard rate was 0.There were also differences in the scale of different enterprises,the exceeding standard rate of small and medium-sized enterprises was significantly higher than that of large enterprises.更多还原
