Morphologic studies were carried out on the liver, kidneys, and small intestine of broiler birds that had been given antibiotics with the feed (virginiamycin, 20.0 ppm, flavomycin, 4.8 ppm, and avotan, 10.0 ppm) in the course of 49 days, kept with a group of controls. The liver of the test birds showed protein and fatty dystrophy, and the kidneys--protein dystrophy. The small intestine showed thinning of the wall and increase in the villi intestinales length. The manifestation of the morphologic changes depended on the amount of the antibiotic taken in. Those of the birds that were offered flavomycin had well manifested lesions, while in birds that were given virginiamycin and avotan only the lesions were more slightly expressed.
对在49天内饲料中添加抗生素（维吉尼亚霉素，20.0 ppm；黄霉素，4.8 ppm；阿伏坦，10.0 ppm）的肉鸡的肝脏、肾脏和小肠进行了形态学研究，并与一组对照鸡饲养在一起。试验鸡的肝脏出现蛋白质和脂肪营养不良，肾脏出现蛋白质营养不良。小肠显示肠壁变薄，肠绒毛长度增加。形态学变化的表现取决于摄入抗生素的量。喂食黄霉素的鸡病变表现明显，而喂食维吉尼亚霉素和阿伏坦的鸡病变表现较轻。
