中文摘要：本研究通过采集2013-2015年间我国不同省份的饲料原料和全价饲料，来分析黄曲霉毒素B1(AFB1)、玉米赤霉烯酮(ZEN)及脱氧雪腐镰刀菌烯醇(DON)的污染情况。其中，研究中共从全国不同省份随机采集了443个饲料原料及127个全价饲料样品。原料样品包括：220个玉米、24个小麦、24个国产DDGS、55个麸皮、20个小麦次粉和低级面粉、37个进口DDGS、34个玉米胚饼粉和29个大豆粉。全价饲料样品包括：25个猪全价饲料（粉）、90个猪价全饲料（颗粒）、6个鸭价全饲料和6个牛全价饲料。研究结果表明，过去3年中，全国各省饲料原料和全饲料严重受到AFB1, ZEN和DON污染，饲料受DON污染最严重，其次是ZEN和AFB1。可见，全饲料及饲料原料中的霉菌毒素污染检测应该常规化。
外文摘要：Background The current study was carried out to provide a reference for monitory of aflatoxin B1 (AFB1), zearalenone (ZEN) and deoxynivalenol (DON) contamination in feed ingredients and complete feeds were collected from different Province in China from 2013 to 2015. Methods A total of 443 feed ingredients, including 220 corn, 24 wheat, 24 domestic distillers dried grains with soluble (DDGS), 55 bran, 20 wheat shorts and red dog, 37 imported DDGS, 34 corn germ meal and 29 soybean meal as well as 127 complete feeds including 25 pig complete feed (powder), 90 pig complete feed (pellet), six duck complete feed and six cattle complete feed were randomly collected from different Province in China, respectively, by high-performance chromatography in combined with UV or fluorescence analysis. Results The incidence rates of AFB1, ZEN and DON contamination of feed ingredients and complete feeds were 80.8, 92.3 and 93.9 %, respectively. The percentage of positive samples for DON ranged from 66.7 to 100 %. Domestic DDGS and imported DDGS presented the most serious contamination AFB1, ZEN and DON contamination levels of feeds ranged from 61.5 to 100 %, indicated that serious contamination over the studied 3-year period. Conclusion The current data provide clear evidence that AFB1, ZEN and DON contamination of feed ingredients and complete feeds in different Province in China is serious and differs over past 3-year. The use of corn, domestic DDGS, imported DDGS and corn germ meal, which may be contaminated with these three mycotoxins, as animal feed may triggered a health risk for animal. Feeds are most contaminated with DON followed by ZEN and AFB1. Mycotoxins contamination in feed ingredients and complete feeds should be monitored routinely in China.
