[Objective] To investigate the effects of estrus synchronization and artificial insemination（AI）technology on the conception rate of dairy goats,providing technical support for improving breeding efficiency and standardized development of the industry. [Method] A total of 3 805 breeding does from 37 dairy goat farms in Longxian County,Shaanxi Province,were studied.Two breeding methods were compared：①natural estrus+AI;and②estrus synchronization（using intravaginal sponges impregnated with fluorogestone acetate combined with PMSG and PG hormone treatments）+AI.The conception rate was determined via ultrasound pregnancy testing,and the effects of farming methods,insemination sites,breeding timing,and other factors were analyzed. [Result] The average conception rate in the estrus synchronization+AI group was 71.56%,significantly higher than that in the natural estrus group （68.56%）.The optimal combination was semi-grazing and semi-penned farming（73.10%）,cervical insemination（74.39%）,and breeding in August（75.49%）. [Conclusion] Estrus synchronization technology can significantly improve the conception rate of dairy goats,with its effectiveness influenced by farming models,operational protocols,and seasonal factors.Tailored implementation plans are recommended to promote high-quality industry development.
