The effect of dietary bacitracin on the growth and feed conversion of guineas has been investigated using graded levels of the antibiotic. The treatments were 0, 11, 22, and 45 mg bacitracin/kg diet. Poorest live weights were recorded by unmedicated guineas. Keets given bacitracin at 11 mg/kg recorded significantly higher live weights (P less than .05) than unmedicated chicks. Best live weights were obtained at a supplementation level of 22 mg/kg; supplementation to 45 mg/kg gave no further growth improvement.
已使用不同梯度水平的杆菌肽研究了日粮中杆菌肽对珍珠鸡生长和饲料转化率的影响。处理组分别为每千克日粮添加0、11、22和45毫克杆菌肽。未用药的珍珠鸡体重增长最差。日粮中添加11毫克/千克杆菌肽的雏鸡体重显著高于未用药的雏鸡（P小于0.05）。每千克日粮添加22毫克杆菌肽时体重增长最佳；添加至45毫克/千克时体重未进一步增加。
