[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.
