Aminoureidosulfone (AUS) was used as a feed additive to prevent mortality in Marek's disease (MD)-infected chickens in the laboratory. Chicks infected with MD virus (5000 plaque-forming units) at 1 day of age were given AUS in the feed from 1 day of age until the experiment was terminated. AUS, at all concentrations tested, reduced mortality due to Marek's disease. Chickens receiving AUS at the 0.002% level had a 4% mortality rate, those receiving 0.005% had 9% mortality, and those receiving 0.01% had 2% mortality; mortality rates in the respective controls were 44%, 49%, and 50%. However, lesion reduction in surviving chicks was minimal. When AUS was withdrawn from the feed, MD-induced mortality increased within two weeks; average body weight decreased also.
氨基脲砜（AUS）在实验室中被用作饲料添加剂，以预防感染马立克氏病（MD）的鸡的死亡。1日龄感染MD病毒（5000个蚀斑形成单位）的雏鸡，从1日龄开始在饲料中添加AUS，直至实验结束。在所有测试浓度下，AUS都降低了马立克氏病导致的死亡率。接受0.002%水平AUS的鸡死亡率为4%，接受0.005%的鸡死亡率为9%，接受0.01%的鸡死亡率为2%；相应对照组的死亡率分别为44%、49%和50%。然而，存活雏鸡的病变减少程度很小。当从饲料中撤掉AUS后，两周内MD诱导的死亡率增加；平均体重也下降了。
