摘　　要：为探讨Ovsynch技术在集约化奶牛场的推广应用效果,于2009年1月—2012年11月选取北京三元绿荷奶牛中心西郊一场2 059头次健康经产中国荷斯坦奶牛按相同胎次、相似体况随机分为对照组(自然发情)和试验组(Ovsynch),比较自然发情和Ovsynch技术处理对奶牛繁殖指标的影响。结果表明:自然发情奶牛与Ovsynch处理奶牛的产后第1次输精间隔天数分别是66.19 d和55.93 d,差异显著(P<0.05);第1情期受胎率分别是35.71%和33.18%(P>0.05);产后55 d配种率分别是12.37%和80.91%,差异显著(P<0.05);产犊间隔分别是395.98 d和386.81 d,差异显著(P<0.05)。结果显示,Ovsynch技术在集约化奶牛场的推广应用能显著地提前奶牛产后第1次输精间隔天数,提高产后55 d配种率,缩短产犊间隔,有效降低奶牛饲养和繁殖管理成本。To investigate the effects of Ovsynch protocol on intensive managing dairy farms in China, a total of 2 059 healthy lactating Chinese dairy cows were selected to compare under spontaneous estrus and Ovsynch protocol at Xijiao First Dairy Farm of Sanyuan Lvhe Dairy Cattle Centre in Beijing between January 2009 and November 2012. The dates of the first insemination after delivery of cows under spontaneous estrus and Ovsynch protocol were 66.19 days and 55.93 days （P〈0.05）, conception rates of the first heat period were 35.71% and 33.18%（P〉0.05）, insemination rates of 55th day after delivery were 12.37% and 80.91%（P〈0.05）, calving intervals were 395.98days and 386.81days（P〈0.05）, respectively. Our results demonstrated that application of Ovsynch protocol in Chinese intensive managing dairy farms brought forward the date of the first insemination after delivery, increased the insemination rate of 55a day after delivery, and shortened the calving interval dramatically; reduced the feeding and breeding management cost of dairy cows effectively.
