| 摘 要： | 依据反刍动物瘤胃可利用非蛋白氮合成菌体蛋白质的特性，应用尿素复合添加剂舔块（简称尿素舔块）饲喂肉用牛，品种为蒙古杂种黄牛。经过分组试验４２ ｄ，结果表明，两个试验组较对照组体重分别提高１４．６ 和１４．８ （ Ｐ ＜ ０．０５），增重成本下降９ 左右，显著提高了经济效益。

| Abstract: | Compound urea additive lumps were used to feed beef cattle on the basis of the characteristics which ruminant rumen can use nonprotein nitrogen to synthesize bacterial protein. The results showed that the body weight of treated group 1 and treated group 2 increased by 14.6% and 14.8% (P<0.05) respectively as compared with that of control group after experiment period of 42 days and the cost for body weight incease decreased by about 9 % and the economic benefit improved significantly. |
