摘　　要：牦牛是青藏高原特殊气候环境条件下形成的特有畜种,饲养方式多为放牧饲养。但是,牦牛的养殖受到地理、气候等各种因素的影响,终年放牧很少进行补饲使牦牛的畜群结构和牧草资源受到严重的影响,牦牛母畜繁殖性能和生产性能降低。冬春季节,草场上牧草资源严重缺乏,导致犊牦牛的生长发育迟缓、发病率、死亡率增加。文章就犊牦牛的不同生长阶段的育肥管理进行综述,为后续犊牦牛的高效育肥提供参考。Yak is a special breed of animal formed under the special climatic environment of Qinghai-Tibet Plateau,and feeding mode is mostly grazing feeding.However,yak breeding is affected by various factors such as geography and climate.The structure of the herd and forage resources of yaks are seriously affected,and the reproductive performance and production performance of yaks are reduced.In winter and spring,the lack of forage resources leads to growth retardation,morbidity and mortality of calves and yaks.The paper reviews the fattening management of yak calves at different growth stages,which can provide reference for efficient fattening of yak calves.
