摘　　要：本研究旨在采用免疫亲和柱高效液相色谱法测定北京地区猪场饲料及饲料原料中赭曲霉毒素A(OTA)的含量,以了解北京地区饲料中OTA污染情况。试验抽样采集北京市昌平区、大兴区、延庆区、平谷区、顺义区5个区县15个猪场131份饲料样[玉米14份、豆粕11份、麸皮13份、干酒糟及其可溶物(DDGS)17份、猪全价配合饲料76份]进行OTA含量的测定。结果表明:玉米、豆粕、麸皮和DDGS中OTA的检出率分别为92.86%、63.64%、76.92%和100.00%,平均含量分别为22.12、10.81、7.78和22.46μg/kg,仅发现玉米中OTA含量超标,超标率为7.14%。乳猪料、仔猪料、中猪料、大猪料、怀孕母猪料和哺乳母猪料中OTA的检出率分别为100.00%、85.70%、85.70%、94.44%、90.00%和100.00%,平均含量分别为4.39、15.74、11.66、13.07、47.75和15.40μg/kg,仅发现怀孕母猪料中OTA含量超标,超标率为20.00%,其他配合饲料中OTA含量均较低。综上所述,不同饲料或饲料原料中OTA含量存在差异,本调研结果发现玉米和怀孕母猪料中OTA含量部分超标,其他猪全价配合饲料及饲料原料中OTA含量均未超标。The zearalenone contents in feeds and feedstuffs were determined using immunoaffinity-HPLC method in this study for knowing the zearalenone contamination situation in feeds and complete feeds of pig farms in Beijing area.Fifty-five feedstuffs which were corn,soybean meal,bran and distillers dried grains with solubles(DDGS) and seventy-six complete pig feeds were collected from 15 pig farms located in Changping district,Daxing district,Yanqing district,Pinggu district and Shunyi district in Beijing area,and the zearalenone contents were determined.The results showed that the detection rates of zearalenone in corn,soybean meal,bran,DDGS and complete feeds were 100.00%,54.45%,100.00%,100.00% and 58.88%,the over standard rates were 0.00%,0.00%,0.00%,41.18% and 0.00%,and the average contents were 109.08,9.19,14.92,882.68 and 58.88 μg/kg,respectively.The results indicate that there are differences in zearalenone contents among different kinds of feeds and feedstuffs.The average content of zearalenone in DDGS is exceeded,but average contents in complete pig feeds and other feedstuffs such as corn,soybean meal and so on are not exceeded.
