摘　　要：国内可应用的繁殖母牛的数量呈现逐渐下降的态势,母牛的受胎率普遍降低,繁殖阶段易出现流产,犊牛成活率相对较为低下,如何提高繁殖母牛的生产能力,已成为畜牧养殖产业需要重点衡量的问题。排卵-定期输精技术作为调控母牛发情周期、促进母牛发情、提高母牛受胎率的重要技术,在当前繁殖母牛群体当中已经得到了广泛的应用。但从总体情况分析,由于集约化规模化肉牛养殖还没有在广大基层地区得以有效的推广,该项技术在应用过程中普遍得不到有效的重视,应用范围有待进一步扩大,需要认真探讨肉牛同期排卵-定期输精技术的特点,并将该项技术在广大基层地区得以有效的推广和应用,转变传统的生产模式,为提高繁殖母牛的生产能力奠定坚实基础。该文同期排卵定时输精的技术原理和主要流程,并提出进一步的发展趋势,希望通过研究对广大同行有所帮助。At present,the number of breeding cows that can be used in China is showing a gradual decline.The conception rate of cows is generally reduced,abortion is prone to occur in the breeding stage,and the survival rate of calves is relatively low.How to improve the production of breeding cows Ability has become a key issue that needs to be measured in the current animal husbandry industry.Simultaneous ovulation-regular insemination technology,as an important technology to regulate the estrus cycle of cows,promote estrus of cows,and increase the conception rate of cows,has been widely used in the current breeding cow population.But from the overall situation,because intensive and large-scale beef cattle breeding has not been effectively promoted in the vast grassroots areas,this technology has generally not received effective attention in the application process,and the scope of application needs to be further expanded,so we need to Seriously discuss the characteristics of simultaneous ovulationregular insemination technology in beef cattle,and effectively promote and apply this technology in the vast grassroots areas,transform the traditional production mode,and lay a solid foundation for improving the production capacity of breeding cows.This study explored the technical principles and main processes of ovulation timing insemination during the same period,and proposed further development trends,hoping to help the majority of colleagues through the research.
