目的 通过胚胎移植技术充分发挥中国西门塔尔牛（草原类型群）优秀母畜的繁殖潜力，为其在繁殖生产中的应用与推广提供技术参考。 方法 对68头青年中国西门塔尔牛（草原类型群）采用CIDR+PG+ADE法进行分批同期发情和胚胎移植，测定发情率、受胎率，根据肉用母牛体况评分技术规程对受体牛的体况进行评分。 结果 中国西门塔尔牛（草原类型）的同期发情率达79.4%，胚胎移植受胎率达40.7%；4月青年母牛发情率相对较高（84.2%），7月受胎率相对较高（45.5%）；20~24月龄膘情中等的青年母牛的移植受胎率（60%）显著高于16~19月龄或过于膘大母牛的受胎率；体况评分4~6分的青年母牛受胎率（46.2%）高于体况评分1~3分和7~9分的青年母牛。1头牛进行胚胎移植的成本为1.34万元。 结论 本地区引种胚胎移植的方法从经济上分析是可行的。

Objectives The reproductive potential of elite female Chinese Simmental cattle (grassland-type herd) was fully utilized with the application of embryo transplantation technology to provide technical references for its application and promotion in reproductive production. Methods 68 young Chinese Simmental cattle (grassland-type herd) were subjected to batch synchronous estrus and embryo transplantation using the CIDR+PG+ADE method. The estrus rate and conception rate were measured. The body condition of the recipient cows was scored according to the technical regulations for evaluating the body condition of beef cows. Results The synchronous estrus rate of Chinese Simmental cattle (grassland-type herd) was 79.4%, and the conception rate of embryo transplantation was 40.7%. The estrus rate of young cows in April was relatively high (84.2%), and the conception rate in July was relatively high (45.5%). The conception rate of embryo transplantation (60%) of young cows aged 20–24 months with moderate fatness was significantly higher than that of cows aged 16–19 months or big fatness. The conception rate (46.2%) of young cows with a body condition score of 4–6 was higher than that of young cows with a body condition score of 1–3 and 7–9. The cost of embryo transplantation for one cow is 13 400 yuan. Conclusions Introducing embryo transplantation in this area is economically feasible.
