In two digestion experiments with wethers and seven feeding experiments with 198 fattening bulls with rations rich in (greater than 55% of the dry matter intake from roughage), the influence of the antibiotic monensin on the digestibility of the ration, on rumen-physiologic characteristic values and on fattening and slaughtering results was investigated. The digestibility of the organic matter and the crude nutrients was not significantly influenced by the use of monensin (20 mg/kg dry matter). The administration of 200 mg monensin per fattening bull and day resulted in an increase of the molar concentration of propionate in the rumen fluid by 9.7 mol%, the concentration of acetate and butyrate decreased by 7.3 resp. 2.8 mol %. On an average of the seven experiments the intake of dry matter was diminished by 5.1% through the use of monensin, the live weight increase remained almost unaffected (3.0% additional increase), feed and energy requirement per kg live weight were improved by 7.9%. The fattening results do not always correspond in the various experiments. The results of the dressing of the carcass, the composition of the carcass and the quality of the meat remained unaffected by the administration of monensin.
在两项针对阉羊的消化实验以及七项针对198头育肥牛的饲养实验中（日粮富含粗饲料，干物质摄入量的55%以上来自粗饲料），研究了抗生素莫能菌素对日粮消化率、瘤胃生理特征值以及育肥和屠宰结果的影响。使用莫能菌素（20毫克/千克干物质）对有机物和粗养分的消化率没有显著影响。每头育肥牛每天服用200毫克莫能菌素，导致瘤胃液中丙酸的摩尔浓度增加9.7摩尔%，乙酸和丁酸的浓度分别下降7.3和2.8摩尔%。在七项实验的平均值中，使用莫能菌素使干物质摄入量减少了5.1%，体重增加几乎未受影响（额外增加3.0%），每千克体重的饲料和能量需求提高了7.9%。育肥结果在不同实验中并不总是一致的。莫能菌素的施用对胴体的屠宰结果、胴体组成和肉质均无影响。
