[Objective] In order to establish a technical scheme suitable for estrus synchronization of dairy goats. [Method] This experiment explored the effect of estrus synchronization of dairy goats through different progesterone suppositories and hormone types,different treatment schemes,different seasons and different parities. [Results] That the PRID was placed on the 0th day,14 : 00;on the 9th day,PMSG 330 IU was injected intramuscularly at 14 : 00. On the 11th day,the thrombus was removed at 14 : 00,and PG 0.2 mg was injected intramuscularly. On the 12th day,the estrus synchronization procedure of 20 : 00 was performed on the first and second parity ewes in the natural estrus season of dairy goats (October-February of the next year). The estrus rate can reach more than 81 %,and the cost is relatively low,which is suitable for large-scale dairy goat farms in Inner Mongolia. [Conclusion] Therefore,we can carry out the estrussynchronous in large-scale dairy goats farms in Inner Mongolia by this scheme, which is easy to operate, cost-effective, and can achieve a high estrus rate.
