| 摘 要： | 在南方高海拔山区，研究不同放牧强度（7．5、15、30和45羊／hm2）和放牧季节对人工改良草地和家畜生产性能的影响，对不同季节人工改良草地适宜载畜量进行探讨。结果表明：不同放牧强度对地上现存量和家畜生产性能有显著影响（P〈0．05）。地上现存量（Yh，g／m2）与放牧率（S，羊／hm2）之间呈线性负相关；日增重（Ya... |

| Abstract: | The improved pasture productivity(by Lolium perenne,Dactylsi glomerata and Trifolium repens)and goat performance were studied under 4 different stocking rates(7.5,15,30 and 45 goat/ha),in order to explore a suitable stocking rate.The results showed that the stocking rate had significant effects on herbage present and goat performance(P<0.05).There were linearly negative correlations between herbage present(Yh,g/m2) and stocking rate(S);Average daily gain(Ya)and stocking rate(S)showed linearly negative corre... |
| Keywords: | improved pasture stocking rate herbage present goat weight gain |
