摘　　要：对青海乐都县在相同饲养条件下的杜藏及藏羊90日龄、180日龄杂交育肥羔羊进行了随机取样称重,统计对比育肥羔羊平均增重和日增重,在相同饲养条件下的育肥效果进行讨论。结果发现,杜藏杂交育肥羔羊180日龄的平均体重达到35.18kg(公羔)和31.08kg(母羔),公羔和母羔日增重分别达到182.44g和160.55g,农区藏系羔羊平均体重达到27.66kg(公羔)和23.83kg(母羔),公羔和母羔日增重分别达到139.24g和108.33g,杜藏杂交育肥羔羊日增重显著高于藏系育肥羔羊(P<0.05)。In this expefiment, -the fattening lambs of Du-Tibetan sheep and Tibetan Sheep-were randomly selected and weighted under the same breeding condition at aged with90d and 180d in Ledu County, the average body weight and daily gain of fattening lambs was measured , and the fattening effect of Du-Tibetan crossbreed sheep and Tibetan Sheep also be discussed. The results showed that the average body weight of Du-Tibetan crossbreed fattening lambs at aged with 180d achieved 35.18kg （Male） and 31.08kg （Famale） respectively, the average daily gain of lambs achieved 182.44g （Male） and 160.55g （Famale.） respectively.The average body weight of Tibetan fattening lambs at aged with 180d achieved 27.66kg （Male） and 23.83kg （Famale） respectively, The average daily gain of lambs achieved 139.24g （Male） and 108.33g （Famale）. The results showed that the average body weight and the average dally gain of Du-Tibetan lambs were significantly higher than that of Tibetan Sheep（P〈0.05 ） .
