The effects of dietary protein source and monensin on growth performance of chicks fed diets containing 121 or 160 mg/kg monensin were investigated. Crossbred chicks (New Hampshire X Columbian) were fed a corn soybean meal diet (24% crude protein) containing 0, 5.0, or 13.0% animal-source protein supplied by various combinations of fish meal and meat and bone meal. Growth rate and gain/feed ratio were measured from 8 to 22 days posthatching. Growth performance was depressed by both 121 and 160 mg/kg monensin with the depression being greater at 160 mg/kg. The type or level of animal-source protein had no effect on the magnitude of growth depression caused by monensin. Growth performance was improved by addition of fish meal and meat and bone meal to the corn-soybean meal diet.
研究了日粮蛋白质来源和莫能菌素对采食含121或160mg/kg莫能菌素日粮雏鸡生长性能的影响。将杂交雏鸡（新汉普夏×哥伦比亚）饲喂含24%粗蛋白的玉米-豆粕日粮，该日粮含有由鱼粉和肉骨粉的不同组合提供的0%、5.0%或13.0%动物源蛋白质。在孵化后8至22天测量生长速率和增重/饲料比。121mg/kg和160mg/kg莫能菌素均使生长性能降低，且160mg/kg时降低幅度更大。动物源蛋白质的类型或水平对莫能菌素引起的生长抑制程度没有影响。在玉米-豆粕日粮中添加鱼粉和肉骨粉可改善生长性能。
