Sixty-seven pig feed samples were examined for the presence of aflatoxins by the method after Velasco, with simultaneous qualitative determination by the thin-layer chromatographic method. All samples were collected at about the same time (June 1977) from central stores, feed preparing plants, storage containers and feeding lines on farms. On the whole, the feeds formed a representative sample of the conditions of pig feed storage and treatment. The presence of aflatoxins was proved in 18 samples (26.8%). One sample (1.4%) showed just traces of aflatoxin, six samples (8.4%) contained 0.014 to 0.45 mg aflatoxins, eight samples (11.2%) contained 0.10 to 0.30 mg aflatoxins, and three samples (4.2%) had 2.7 to 3.5 mg aflatoxins per 1 kg of feed. The samples with the highest aflatoxin concentrations came from metallic storage containers for complete feed mixtures in front of the pigsties.
采用韦拉斯科方法对67份猪饲料样本进行黄曲霉毒素检测，并同时用薄层色谱法进行定性测定。所有样本均于1977年6月前后从中央仓库、饲料加工厂、储存容器以及农场的喂料管线中采集。总体而言，这些饲料构成了猪饲料储存和处理状况的代表性样本。18份样本（26.8%）被证实含有黄曲霉毒素。1份样本（1.4%）仅显示有微量黄曲霉毒素，6份样本（8.4%）含有0.014至0.45毫克黄曲霉毒素，8份样本（11.2%）含有0.10至0.30毫克黄曲霉毒素，3份样本（4.2%）每千克饲料含有2.7至3.5毫克黄曲霉毒素。黄曲霉毒素浓度最高的样本来自猪舍前用于存放全价饲料混合物的金属储存容器。
