中文摘要：镰刀菌产生有毒物质称为真菌毒素，可导致疾病，对谷物、家畜和人类产生有害影响。脱氧雪腐镰刀菌烯醇（DON），也称为呕吐毒素，是已知会导致家畜呕吐的镰刀菌毒素之一。本研究显示了2009年至2016年间韩国饲料（复合饲料和饲料原料）中的脱氧雪腐镰刀菌烯醇的分布情况。在五个时间点共收集了653个国内样本，包括494个复合饲料样本和159个饲料成分样本。使用高效液相色谱（HPLC）分析DON污染水平，使用免疫亲和柱（IAC）进行预处理。检测限（LOD）和定量限（LOQ）分别估计为1-10μg/ kg和3-35μg/ kg。 160个猪饲料样品中的两份复合饲料（两种妊娠母猪饲料样品）超过欧盟委员会（EC）指导值，而没有饲料成分样品超过EC或韩国指导值。复合饲料和饲料成分的平均污染水平在统计学上存在显著差异，表明随着时间的推移污染水平呈下降趋势。
外文摘要：The Fusarium fungi produce toxic substances called mycotoxins, which can cause disease and harmful effects in grains, livestock, and humans. Deoxynivalenol (DON), also known as vomitoxin, is one of the Fusarium mycotoxins that is known to cause vomiting in livestock. This study shows the occurrence of deoxynivalenol in feedstuffs (compound feed and feed ingredients) between 2009 and 2016 in South Korea. A total of 653 domestic samples were collected at five time points, including 494 compound feed samples and 159 feed ingredient samples. DON contamination levels were analyzed using high-performance liquid chromatography (HPLC) with pretreatment using an immunoaffinity column (IAC). The limit of detection (LOD) and the limit of quantification (LOQ) were estimated at 1-10 mu g/kg and 3-35 mu g/kg, respectively. Two compound feeds (two gestating sow feed samples) out of 160 pig feed samples exceeded the European Commission (EC) guidance value, while no feed ingredient samples exceeded the EC or South Korean guidance values. There were statistically significant differences in the mean contamination levels of compound feed and feed ingredients that indicated a decreasing trend over time.
