In a series of experiments, leghorn-type chickens were fed diets containing from 0 to 880 mg of ascorbic acid/kg of feed beginning 1 day before air-sac challenge with Escherichia coli. Infection occurred in 46/60 (76%) of the controls and in 12/63 (19%) of those given feed containing 330 mg of ascorbic acid/kg. Levels of ascorbic acid above and below 330 mg/kg feed were less effective.
在一系列实验中，来亨鸡在受到大肠杆菌气囊攻击前1天开始被喂食每千克饲料含0至880毫克抗坏血酸的日粮。对照组60只中有46只（76%）发生感染，而喂食每千克含330毫克抗坏血酸饲料的鸡中63只里有12只（19%）发生感染。每千克饲料中抗坏血酸水平高于和低于330毫克时效果较差。
