Efficacy of virginiamycin (22 mg/kg) in combination with no drug, amprolium, carbarsone, halofuginone, or monensin, was studied. Male and female turkeys were raised to market age in five experiments conducted from 1983 to 1987. Body weights and feed:gain responses to virginiamycin for males and females were positive and significant (P less than .05). Virginiamycin resulted in mean 5.2 and 6.3% body weight responses and 3.3 and 2.2% feed:gain responses for males at 19 or 20 wk of age and for females at 16 or 17 wk of age, respectively. Mortality rates were low in all studies, and were not influenced by virginiamycin. In a processing study, virginiamycin in combination with halofuginone did not affect shrinkage, yield, or market grade. Feed was utilized by males and females 3.9 and 3.0%, respectively, more efficiently than expected with dietary virginiamycin, compared with results predicted by a simulation modeling technique. Profitability was considerably greater with dietary virginiamycin using actual data than with simulated feed consumption data.
研究了维吉尼亚霉素（22毫克/千克）与无药物、氨丙啉、卡巴胂、常山酮或莫能菌素联合使用的效果。在1983年至1987年进行的五项实验中，将雄性和雌性火鸡饲养至上市年龄。雄性和雌性对维吉尼亚霉素的体重和料重比反应呈阳性且显著（P小于0.05）。维吉尼亚霉素分别使19或20周龄的雄性和16或17周龄的雌性体重平均增加5.2%和6.3%，料重比分别降低3.3%和2.2%。在所有研究中死亡率都很低，且不受维吉尼亚霉素影响。在一项加工研究中，维吉尼亚霉素与常山酮联合使用不影响胴体收缩率、产肉率或市场等级。与模拟建模技术预测的结果相比，雄性和雌性使用饲料的效率分别比预期的含维吉尼亚霉素日粮高3.9%和3.0%。使用实际数据时，含维吉尼亚霉素日粮的盈利能力比使用模拟饲料消耗数据时显著更高。
