Three trials were conducted with finishing steers to study the effect of feeding sorbitol alone or combined with monensin. For each trial 15 pens of eight steers were fed high-corn-silage diets. In the first two trials three pens of eight steers each were fed no additive, 35 g of sorbitol, 350 mg of monensin, or 30 g of sorbitol plus 350 mg of monensin per day. In Trial 1 three pens were fed 200 g of sorbitol per animal every 6 d, and in Trial 2 three pens were fed 60 g/d of sorbitol plus 350 mg/d of monensin. For the third trial, three pens were fed 0, 20, 40, or 80 g/d of sorbitol per animal and three pens were fed 40 g/d after 56 d; all the steers were fed 350 mg/d of monensin. In the first trial sorbitol had no effect on daily gain, and monensin increased (P < .05) daily gain. Intake of DM was lower (P < .05) for the steers fed sorbitol (35 g/d). Dry matter intake/gain was improved by feeding monensin (P < .05) or 35 g/d of sorbitol (P < .07). The improvement amounted to 18% when the additives were used in combination. In the second trial daily gains were similar for the cattle fed all diets. Dry matter intake was lower (P < .05) for steers fed monensin or 60 g/d of sorbitol and tended to be lower (P < .12) for the cattle fed 35 g/d of sorbitol. Dry matter intake/gain tended to be lower for cattle fed monensin and sorbitol, especially when fed in combination.(ABSTRACT TRUNCATED AT 250 WORDS)
进行了三项试验，用育肥牛来研究单独饲喂山梨醇或与莫能菌素联合饲喂的效果。每项试验中，15个圈舍，每个圈舍8头育肥牛，均饲喂高玉米青贮饲料。在前两项试验中，每个圈舍8头育肥牛的三个圈舍分别不添加任何添加剂、每天添加35克山梨醇、350毫克莫能菌素或30克山梨醇加350毫克莫能菌素。在试验1中，三个圈舍的每头牛每6天饲喂200克山梨醇，在试验2中，三个圈舍的牛每天饲喂60克山梨醇加350毫克莫能菌素。在第三次试验中，三个圈舍的每头牛每天分别饲喂0、20、40或80克山梨醇，三个圈舍的牛在56天后每天饲喂40克山梨醇；所有的牛每天均饲喂350毫克莫能菌素。在第一次试验中，山梨醇对日增重没有影响，而莫能菌素提高了（P < .05）日增重。饲喂山梨醇（35克/天）的育肥牛的干物质摄入量较低（P < .05）。通过饲喂莫能菌素（P < .05）或35克/天的山梨醇（P < .07），干物质摄入量/增重得到改善。添加剂联合使用时，改善幅度达18%。在第二次试验中，饲喂所有日粮的牛的日增重相似。饲喂莫能菌素或60克/天山梨醇的育肥牛的干物质摄入量较低（P < .05），饲喂35克/天山梨醇的牛的干物质摄入量趋于较低（P < .12）。饲喂莫能菌素和山梨醇的牛的干物质摄入量/增重趋于较低，尤其是联合饲喂时。（摘要截断于250字）
