摘  要：
[目的]为了确保美系短角牛选育及推广利用工作顺利进行。[方法]对云南省种羊场扩繁选育的全日制放牧条件下短角牛进行体重、体尺测定。采用牛体重、体尺测定的常规方法,分别测定初生、6月龄、12月龄、18月龄、24月龄、36月龄和成年等不同发育阶段公母牛的体重和体尺。[结果]短角牛种公牛有两个增重高峰,分别是从初生到6月龄和从36月龄到成年;而短角牛母牛的增重从初生到12月龄增重为最快,以后的增重速度变慢。成年公牛体重821.56±62.67kg,体高143.44±5.00cm,体斜长172.89±7.85cm,胸围207.50±7.98cm;母牛分别为543.14±45.20kg,135.34±4.56cm,160.59±7.90cm和187.96±7.20cm。[结论]美系短角牛在云南省种羊场生长发育良好,具备了一定的供种能力。
