[目的]为了增加高原生态环境下犊牦牛的初生重，提高犊牦牛成活率。[方法]本研究采取了在母牦牛怀孕后期补饲的方法，在怀孕后期，母牦牛自然放牧回圈后，每晚每头母牦牛补饲250g母牦牛浓缩精料补充料，连续补饲3个月。[结果]表明，试验组犊牦牛的初生重显著大于对照组（P〈0．01）；而且母牦牛产后掉膘少，产后发情率高。[结论]对地处高海拔地区的自然放牧母牦牛围产期补饲母牦牛浓缩精料补充料后，能有效提高犊牦牛的初生重。
[目的]為瞭增加高原生態環境下犢牦牛的初生重，提高犢牦牛成活率。[方法]本研究採取瞭在母牦牛懷孕後期補飼的方法，在懷孕後期，母牦牛自然放牧迴圈後，每晚每頭母牦牛補飼250g母牦牛濃縮精料補充料，連續補飼3箇月。[結果]錶明，試驗組犢牦牛的初生重顯著大于對照組（P〈0．01）；而且母牦牛產後掉膘少，產後髮情率高。[結論]對地處高海拔地區的自然放牧母牦牛圍產期補飼母牦牛濃縮精料補充料後，能有效提高犢牦牛的初生重。

[objective]This study was to increase eau ecological enviroment. [method] Supplementa 250g supplementary concentrat was feed every day birth weight and survival rate of yak calves under plat ry af concentrate was fed during late pregnancy of yak. ter natural grazing for 3 consecutive months in yak. [Result]The result showed that the birth weight in experimental group was observably higher than that of control group （ P 〈0.01）. The oestrus rate of mother yaks was higher, and the postpartum body condition was good. [conclusion]The yaks during late pregnancy feeding supplementary concentrate could efficiently improve birth weight in Qinghai plateau.
