Four feeding trials were conducted in which Large White turkeys were fed diets containing either amprolium or butynorate to 8 or 9 weeks of age to female and male turkeys, respectively. Diets fed during the study contained from 0 to 10% supplemental fat to provide a range of dietary energy levels. Poults were maintained on built-up wood shavings litter with no attempts to induce coccidiosis. Turkeys fed diets with amprolium did not grow as well or convert feed as efficiently as those fed butynorate at 8 or 9 weeks of age when the additives were withdrawn. However, at market weights or feed utilization between turkeys fed the two different anticoccidials.
进行了四项饲养试验，分别对雌性和雄性大白火鸡饲喂含氨丙啉或丁炔酯的日粮至8周龄或9周龄。研究期间饲喂的日粮含有0%至10%的补充脂肪，以提供一系列日粮能量水平。雏禽饲养在堆积的木屑垫料上，未试图诱发球虫病。当撤去添加剂时，8周龄或9周龄时，饲喂含氨丙啉日粮的火鸡生长不如饲喂丁炔酯日粮的火鸡，饲料转化率也不如后者。然而，在上市体重或饲料利用率方面，两种不同抗球虫药饲喂的火鸡之间存在差异。
