奶牛同期发情（Ovsynch）处理技术是现代牧场提升繁殖效率与经济效益的核心手段。该技术通过激素调控与精准管理,将奶牛发情周期集中在产后50~80 天的“黄金受孕期”,有效缩短空怀天数、提高受胎率,并降低漏配风险。本文系统阐述了Ovsynch处理技术在牧场中的分层实施方案,包括产后未配种牛、空怀牛、青年牛及成母牛等不同群体的处理策略,并分析了牛只混群、牛颈夹利用率、药物注射有效性及发情揭发等关键影响因素。同时,提出以“定时配种（TAI）占比”为核心的数据监督体系,推动牧场实现从经验管理向数据驱动的转型,为提升牧场繁殖管理水平提供实践依据。
Estrus synchronization technology in dairy cows is a core method for modern dairy farms to enhance reproductive efficiency and economic benefits. By employing hormonal regulation and precise management, this technology concentrates the estrous cycle of dairy cows within the "golden breeding period" of 50~80 days postpartum, effectively reducing days open, improving conception rates, and minimizing the risk of missed breeding. This paper systematically elaborated on the stratified implementation of estrus synchronization technology on dairy farms, including treatment strategies for different groups such as postpartum unbred cows, open cows, heifers, and adult cows. It also analyzed key influencing factors such as animal mixing, headlock utilization, effectiveness of drug administration, and estrus detection. Furthermore, a data supervision system centered on the "TAI proportion" is proposed to promote the transition from experience-based management to data-driven decision-making, providing practical guidance for improving reproductive management on dairy farms.
