Mature White Leghorn hens that had been fed a commercial laying diet were changed to a wheat-based diet over a period of 42 days. Two groups were formed based on equivalent egg production and body weights and randomly assigned to either a control (noncontaminated) wheat diet or a naturally contaminated deoxynivalenol (DON, vomitoxin) wheat diet (18 mg DON/kg). Hens were provided their respective diets and water ad libitum for 112 days along with 16 hr of light. The DON-contaminated diet did not significantly influence hen body weights, hen day egg production, egg weights, or efficiency of feed utilization. Internal egg quality, as measured by albumin height, was slightly, although significantly, improved by feeding the DON-contaminated wheat diet. Egg shell weight and percent egg shell were slightly, although significantly, decreased by feeding the DON-contaminated diet, whereas shell thickness was not altered. No deleterious effects were observed in fertility, hatchability, or chick weights at hatch. The results indicate that laying hens are affected only slightly when fed naturally contaminated wheat diets containing approximately 18 mg DON/kg for 112 days.
将一直喂食商业产蛋日粮的成年白来航鸡在42天的时间内更换为以小麦为基础的日粮。根据产蛋量和体重相当的原则将鸡分为两组，并随机分配到对照组（未受污染）小麦日粮组或天然受脱氧雪腐镰刀菌烯醇（DON，呕吐毒素）污染的小麦日粮组（18毫克DON/千克）。母鸡自由采食各自的日粮和饮水，持续112天，并给予16小时光照。受DON污染的日粮对母鸡体重、日产蛋量、蛋重或饲料利用率没有显著影响。通过蛋白高度衡量的蛋内部品质，在喂食受DON污染的小麦日粮后虽有显著改善，但改善程度较小。喂食受DON污染的日粮后，蛋壳重量和蛋壳百分比虽有显著下降，但下降幅度较小，而蛋壳厚度未发生改变。在受精率、孵化率或出雏时雏鸡体重方面未观察到有害影响。结果表明，产蛋鸡在112天内喂食天然受污染且含有约18毫克DON/千克的小麦日粮时，受到的影响较小。
