| 摘 要： | 草羔育肥是发展草原季节畜牧业的重要措施。本文探讨了以红豆草茬地放牧为主,结合补饲青干草对甘肃高山细毛羊(GF)和边甘杂种(BG)羔羊育肥的初步效果。试验按放牧、放牧+补饲及圈饲三个阶段进行。补饲又分燕麦、红豆草及燕麦+红豆草三种处理。分别从体增重、牧草利用率和肉用性能等方面作了比较。结果表明,经80天育肥试验,两种羔羊的期末活重和羔羊胴体重均分别达到35公斤和17公斤以上(符合国际市场出售商品羔羊的标准)。三种补饲处理之间差异显著(P<0.05),其中以补饲混合干草(燕麦草+红豆草)的效果为最佳(P0.05)。

| Abstract: | A study on grass lamb fattening with lambs of Gansu Fine Wool(GF)and crossbred of Border Leceister+GF(BG)by grazing on sainfoin stubble fields and adding with oat and sainfoin green hay on the College Herbage Station of Gansu Agric.Univ.during 1986—1987 Was conducted. Comparisons were made among the three treatments, i.e.pure oat hay,pure sainfoin hay and mixed hay of oat and sainfoin on the two types of lamb. Results showed that live weight of 7 month BG lamb or 9 month GF lamb averaged over 35kg,carcass weignt over 17kg and dressing percentage for 47—49％.The group of adding oat+sainfoin performanced much better than the other two treatments(PO.05).Through the analysis of cost—profit,the profit rate was 17.13％. |
