| 摘 要： | 将30只（15只♂、15只♀）小尾寒羊（6）与细毛羊（♀）的杂交一代周岁羊，采用单因子设计，随机按性别配对，体重组间差异不显著（P〉0．05）原则分为三个组，每组10只。正试期，1组和2组，每日每羊供给精料200g，分别按供给精料量的4％和8％添加PAL缓释非蛋白氮饲喂，对照组（3组）每日每羊只喂精料200g，比较饲喂效果。结果表明，在61d正试期，饲喂PAL缓释非蛋白氮的1组和2组，日增重分别较对照组提高75．25％和97．37％，均差异极显著（P〈0．01）；分别较对照组净获增重收入37．15元和47．03元。同时，解决了舍饲绵羊啃食墙土与食其他异物的问题。饲喂效果显著。 |

| Abstract: | Thirty hoggs were randomly assigned three concentrate treatments of suPPlemented with 0%, 4%, 8% of the comPex additive of urea NPN slow - release with Palygorskite. 200g concentrate was given for each hogg everyday with feeding forage grass to aPPetite. The experiment was carried out for 61 days. The result was as follows ： the treatment of 4% and 8% significantly increased daily gain by 75.25% and 97.37%, and also significantly increased net income by ￥ 37.15 and ￥ 47.03 than the treatment of 0% （P 〈 0.01）. |
