摘　　要：采用相同月龄的波德代杂种与当地土种蒙古羊进行短期育肥,结果表明:育肥期平均日增重,杂种公羔为247g,杂种母羔为263g,土种羊为183g,杂种羔羊与土种羊相比,平均日增重差异显著(P〈0.05〉,说明波寒杂种羔羊的肥育性能好于土种羔羊,且在相同投入条件下以杂种羔羊肥育后经济效益明显。In grazing plus supplement feeding condition, 3 - month old crossbreds lambs of Borderdale sheep （ ♂） × Small Tailed Han sheep（ ♀） were selected to evaluate the fattening method. Finally,average daily gain （ADG） in 3 -month old crossbreds lambs group was 255 g/d,however the Mongolian sheep was 183 g/d. The result showed： the ADG of 3 - month old crossbreds lambs were significant higher than that of local ones and in the same conditions, the economic benefits of fattening from crossbreds lambs was higher than that from Mongolian sheep＇ lambs.
