Six trials were conducted at various locations to determine the response of broiler chickens to combinations of zinc bacitracin and roxarsone when fed in the presence of narasin. The addition of zinc bacitracin at 55 mg per kg significantly improved growth rate and feed utilization when data from all locations were combined. There was no effect of roxarsone fed at 50 mg per kg on BW or feed utilization, nor was there an interaction of roxarsone and zinc bacitracin on BW. There was a significant interaction of roxarsone and zinc bacitracin for feed utilization; addition of zinc bacitracin significantly improved feed utilization both in the presence and absence of roxarsone, but the improvement was greater in the absence of roxarsone.
在不同地点进行了六项试验，以确定在有甲基盐霉素存在的情况下，当肉仔鸡饲喂杆菌肽锌和洛克沙胂的组合时的反应。当合并所有地点的数据时，每千克添加55毫克杆菌肽锌显著提高了生长速度和饲料利用率。每千克饲喂50毫克洛克沙胂对体重或饲料利用率没有影响，洛克沙胂和杆菌肽锌对体重也没有交互作用。洛克沙胂和杆菌肽锌在饲料利用率方面存在显著交互作用；添加杆菌肽锌在有和没有洛克沙胂的情况下均显著提高了饲料利用率，但在没有洛克沙胂的情况下提高幅度更大。
