在甘肃省肃南县康乐草原，以5月龄放牧型甘肃高山细毛羊为研究对象，开展60 d的短期育肥试验。试验期间试验组从夏草场转入冬草场放牧，并辅以少量补饲；对照组按照传统饲养模式从夏草场转入春秋草场，自由放牧。结果表明，短期育肥的放牧羔羊育肥后体重和日增重均显著高于对照组羔羊(P ＜ 0.01)，短期育肥经济效益显著。

The 5 months Gansu fine wool sheep in Gansu province Kangle pasture， we study short-term fattening 60 days tests in the test time， the experiment group from summer pasture to winter pasture， grazing with small amount of supplementary feeding， control group according to the traditional breeding mode from summer pasture， transferred to the spring pasture， just grazing. The result shows that the experimental group weight and daily gain are significantly higher than the control group(P < 0.01)， short-term fattening economic benefit is remarkable.
