摘　　要：[目的]为研究繁殖母牦牛配种期营养对连产率的影响,并为实现天祝白牦牛"一年一胎"高效繁殖提供技术初探,在祁连山生态保护政策大环境下,传统畜牧业生产方式如何实现减畜增效提供参考。[方法]以天祝白牦牛繁殖母牛连产率为研究对象,通过相同草原环境下2个村组同一年产犊母牦牛中连胎母牛数所占比例进行对比,分析不同的饲养放牧方式对天祝白牦牛连产率的影响。[结果]结果表明:同等放牧环境下,以草定畜自然放牧方式,牛群数量相对减少,但比起传统扩群饲养环境下母牛连胎率提高了30%～40%,效果明显。[Objective] The aim of this study was to explore the effect of nutrition during the mating period on the continuous yield of Tianzhu white yak, so as to achieve a high "one-child-a-year" of Tianzhu white yak. Preliminary study on effective reproduction technology provided reference for promoting efficiency of breeding in traditional animal husbandry production mode under the environment of ecological protection policy in Qilian Mountains.[Method] Taking Tianzhu white yak as the research object, this study compared the proportion of continuous cows in the same year in two village groups under the same grassland environment, and analyzed the influence of different feeding and grazing methods on the continuous yield of Tianzhu white yak.[Result] The results showed that under the same grazing environment, the number of cattle in the natural grazing mode of grass-fixed cattle was relatively reduced, but the continuous pregnancy rate of cows was increased by 30%~40% compared with that in the traditional extended-herd feeding environment.
