Two experiments were conducted with broilers to determine the effect of Virginiamycin supplementation on performance and shank pigmentation. Virginiamycin supplementation at 10 ppm resulted in significantly increased body weights in both experiments. Feed efficiency was significantly improved in Experiment 1 by the supplementation of 5 and 10 ppm Virginiamycin. In Experiment 2, 20 ppm Virginiamycin was included and resulted in no greater response than that observed at 10 ppm. Pigmentation values as measured by a reflectance colorimeter and Roche color fan favored (P less than or equal to .05) Virginiamycin supplementation in both experiments. Data indicated that when the diet was supplemented with Virginiamycin an increase in the utilization of xanthophyll resulted. Mortality was not influenced by dietary treatment.
进行了两项试验，以确定添加维吉尼亚霉素对肉鸡生产性能和胫部色素沉着的影响。在两项试验中，添加10 ppm的维吉尼亚霉素均使体重显著增加。在试验1中，添加5 ppm和10 ppm的维吉尼亚霉素显著提高了饲料效率。在试验2中，添加了20 ppm的维吉尼亚霉素，但与10 ppm时相比，未产生更大的反应。在两项试验中，通过反射比色计和罗氏比色扇测量的色素沉着值均表明添加维吉尼亚霉素具有优势（P≤0.05）。数据表明，日粮中添加维吉尼亚霉素可提高叶黄素的利用率。死亡率不受日粮处理的影响。
