摘要:
为探讨中度放牧条件下放牧方式对家畜生产力的影响,开展了牦牛单牧(YG)、藏羊单牧(SG)、牦牛藏羊1∶6混牧(MG1∶6)、牦牛藏羊1∶4混牧(MG1∶4)和牦牛藏羊1∶2混牧(MG1∶2)5个控制性放牧试验,研究了牧草生长季不同生长时期对家畜日增重的影响以及不同放牧方式对牦牛和藏羊暖季增重、牧草营养和家畜采食量的影响。结果表明:1)在牧草返青期和生长期,牦牛和藏羊的日增重显著大于牧草枯黄期(P<0.05);2)牦牛和藏羊日增重在不同的放牧方式下无显著差异(P>0.05),而牦牛暖季增重在YG下最高,在MG1∶2和MG1∶6相对较高,藏羊暖季增重在MG1∶2中最高,在SG和MG1∶4相对较高;3)不同放牧方式下牧草营养和单位面积家畜采食量无显著差异(P>0.05),单一家畜放牧单位面积增重SG最高,牦牛藏羊两种家畜混合放牧则MG1∶2单位面积增重最高。综上,牧草枯黄期牦牛和藏羊的补饲对于维持其生产性能具有重要的意义,且MG1∶2对于牦牛和藏羊生产是一种较优的组合生产方式。
