When applied to male Trakiiska tunkorounna lambs of initial weight 18.6 kg in the course of 90 days at concentrations of 6 g, 12 g, and 24 g per ton of forage slinomycin brought about a rise of liveweight and average weight gain in the treated animals (for the weight gain 12.2, 16.7, and 19.4 per cent, respectively, as against the controls). The conversion rate (intake per kilogram of weight gain) was by 9.7, 16.6, and 22.2 per cent, respectively, higher. The intake of forage progressively dropped when offering higher concentration of the antibiotic, particularly during the second half of the experimental period. Highest was the effect of adding 24 g salinomycin to a ton of forage. Salinomycin induced no essential changes in the slaughter indices and in the content of cyanocobalamin in the meat. However, cyancobalamin was found to be at a higher level in the liver.
当以每吨饲料6克、12克和24克的浓度，在90天内应用于初始体重为18.6千克的雄性特拉基斯卡敦科伦纳羔羊时，盐霉素使受试动物的体重增加，平均增重提高（增重分别比对照组高12.2%、16.7%和19.4%）。转化率（每千克增重的摄入量）分别提高了9.7%、16.6%和22.2%。提供较高浓度的抗生素时，饲料摄入量逐渐下降，尤其是在实验期的后半段。在每吨饲料中添加24克盐霉素的效果最佳。盐霉素对屠宰指标和肉中钴胺素含量没有产生实质性变化。然而，发现肝脏中钴胺素的含量较高。
