Hens fed a diet containing 3310 micrograms of AFB1 and 1680 micrograms of AFB2 per kg feed for 28 days showed a significant decrease in egg production and egg weights by wk 3 and 4 of feeding, respectively. Transfer of aflatoxins to the eggs occurred rapidly, reaching maximum levels after 4-5 days, and remained relatively constant throughout aflatoxin feeding. The mean values for combined residue levels in eggs were less than 0.5 microgram/kg. Levels of AFB2, AFM1 and AFM2 were similar in yolk and albumen while levels of B1 and B2a were higher in the yolk. Upon removal of the aflatoxin-containing diet, residues in eggs decreased rapidly. Clearance of aflatoxin residues from the albumen occurred faster than from the yolk. Thus, no residues were detected in the albumen and in the yolk after 5 and 7 days of withdrawal, respectively. No aflatoxin residues could be recovered from whole eggs after feeding the aflatoxin-free diet for 4 days.
给母鸡喂食每千克饲料中含有3310微克黄曲霉毒素B1和1680微克黄曲霉毒素B2的日粮，持续28天，结果显示，在喂食的第3周和第4周，产蛋量和蛋重分别显著下降。黄曲霉毒素迅速转移到鸡蛋中，在4 - 5天后达到最高水平，并且在整个黄曲霉毒素喂食期间保持相对稳定。鸡蛋中黄曲霉毒素残留总量的平均值低于0.5微克/千克。黄曲霉毒素B2、M1和M2在蛋黄和蛋清中的含量相似，而B1和B2a在蛋黄中的含量更高。去除含黄曲霉毒素的日粮后，鸡蛋中的残留量迅速下降。黄曲霉毒素残留从蛋清中的清除速度比从蛋黄中更快。因此，分别在停止喂食5天和7天后，蛋清和蛋黄中均未检测到残留。在喂食无黄曲霉毒素日粮4天后，全蛋中无法检测到黄曲霉毒素残留。
