摘要

[目的]通辽市是中国西门塔尔牛（草原类群）主产区,黄牛质量、技术集成和产业化经营水平等都实现了率先跨越。但是,母牛繁殖成活率低一直是制约黄牛业快速、健康发展的瓶颈。[方法]通过全市整体调查和典型镇对比分析,总结规律。[结果]提高繁殖成活率,必须从母牛吃饱吃好做起,抓好膘情、发情、冷配、受胎,接产、保育等每个生产环节,才能取得好的养牛效益。[结论]找出了通辽市母牛繁殖成活率低的成因及对策,期望对牛群＂多生少死＂有借鉴作用。%【Objective】Tongliao city is the major producing area of Chinese Simmental cattle（Grassland groups）.Many aspects have been realized a leading breakthrough development,such as the quality of the cattle,the integration of the technology,the level of the industrial management and so on.But the low reproductive survival rate of cows has been the bottle neck restricting the fast and healthy development of the cattle industry for a long time.【Method】The objective law was summarized according the comparative analysis on integral survey result of the whole city and typical town.【Result】 In order to increase the reproductive survival rate,each production links should be considered,especially the body conditions,estrus,frozen semen insemination,fertilization,delivery and nursing.【Conclusion】 We found out the cause and countermeasures of the low reproductive survival rate of cows in Tongliao city,expecting it would be helpful to the more birth and less death of cows.
