| 摘 要： | 玉米品种白马牙经追施不同量的氮肥（0、150、300kg尿素／hm^2），收割后制成青贮玉米的CP含量就会不同，用该青贮玉米饲喂育成羊，观测增重情况．结果显示，施尿素300kg／hm^2组的增重显著（P〈0．05），平均日增重是136．9g，高于未施尿素的对照组，提高幅度达26．10％．

| Abstract: | White house tooth,a maige strain,feritilized with different quantity of the nitrogenous during growth,was silaged,with its crude protein content being various.The silage-maige was fed to experimental lambs to of see weight gain.The result showed the urea silage-maize group(300kg/hm~2 )had the best fodder conversion,with its 136.99 liveweight gain being much higher than other groups.The differences were significant(p<0.05)compored with control groups. |
