| 摘 要： | 在青藏高原高寒草甸区比较研究了多年生人工草地和天然草地暖季放牧对犊牦牛生长的影响,结果得出:不同放牧方式下,1岁牛的个体增重差异明显,人工草地轮牧>人工草地连续放牧>天然草地连续放牧,2岁牛的增重不受草地和放牧方式的影响,个体增重、日增重和单位草地面积的增重都高于1岁犊牦牛。

| Abstract: | Trials on effect of yak grazing artificial grassland and native rangeland in warm-season on gain were conducted in the Qinghai-Tibetan Plateau. The trial contained 3 grazing treatments: continuous grazing artificial grassland, rotational grazing artificial grassland and continuous grazing native rangeland. The results were as following: In different grazing treatments, gains of individual yearling calves were significantly different, rotational grazing in artificial grassland>continuous grazing in artificial grassland >continuous grazing in native rangeland. Gains of the 2-year-old calves were not significantly different in grazing treatments, individual gains, average daily gain and gains per hectare were all higher than those of the yearlings'. It is suggested that 2-year-old caves should be used when grazing artificial grassland in warm-season. |
