An experiment was carried out with 36 pigs, weighing 8 to 70 kg, divided into 4 groups to test the growth-promoting effect of kormogrisin-40 given with the feed. The animals were fed on one and the same standard combined feed--a basic ration to which antibiotics were added in the form of a premix as follows: group I (controls); group II--zinc-bacitracin in conc. of 40 ppm; group III--grisin in conc. of 5 ppm; and group IV--grisin in conc. of 12 ppm. It was ascertained that growth stimulation was best manifested with group IV--the average daily gain increased by 17 per cent, and the consumption of feed per kilogram of gain decreased by 13.2 per cent. Second in effect ranked group III--13.0 and 9.6 per cent respectively. When concentrations of 5 and 12 ppm of grisin were used with pigs, and these were slaughtered without observing any withdrawal times there were residual amounts of the antibiotic in the meat and the parenchymal organs.
用36头体重8至70千克的猪进行了一项实验，将其分为4组，以测试饲料中添加40型科尔莫格菌素的促生长效果。给这些动物喂食相同的标准混合饲料——一种基础日粮，以预混剂形式添加如下抗生素：第一组（对照组）；第二组——浓度为40 ppm的杆菌肽锌；第三组——浓度为5 ppm的格菌素；第四组——浓度为12 ppm的格菌素。结果表明，第四组的生长刺激效果最佳——平均日增重提高了17%，每千克增重的饲料消耗量减少了13.2%。效果排第二的是第三组——分别提高了13.0%和9.6%。当猪使用浓度为5 ppm和12 ppm的格菌素，且未观察停药期就进行屠宰时，肉和实质器官中存在抗生素残留量。
