摘　　要：【目的】为了探索定时输精技术在舍饲肉牛繁殖上的应用效果,探索建立一套符合云南楚雄地区舍饲肉牛养殖场使用的定时输精程序。【方法】本试验采用ovsynch程序对于2个肉牛养殖场的21头经产健康母牛进行定时输精试验,并设对照组。经统计分析:试验组母牛第一情期受胎率71.4%,对照组母牛第一情期受胎率64.5%。【结论】试验组母牛的第一情期受胎率较对照组母牛的第一情期受胎率数据经卡方(x2)分析,差异显著。该技术可以在楚雄地区舍饲肉牛养殖场推广运用。[Objective]The experiment was conducted to probe into the application of timed artificial in-semination to the reproduction of stall-feed cattle, in an effort to establish a set of timed artificial insemina-tion procedures in line with actual situations of the stall-feed beef farms in Chuxiong of Yunnan. [Methods]With the adoption of ovsynch program, timed artificial insemination was experimented among the 21 multiparous healthy cows and compared with the Control Group. According to the experiments, concep-tion rate of the experimented cows during the first-cycle estrus came to 71.4% while that of the Control Group was 64.5%. [Conclusions]Chi-square （x2） ana conception rate during the first-cycle estrus between ly th sis showed that there was significant difference in e experimented cows and those from the Control Group. Therefore, this technology can be popularized among stall-feed beef farms in Chuxiong.
