| Abstract: | [Objective] To explore the effect of LRH-A3 and PGF2a on the synchronous estrus of cows. [Method] The LRH-A3 was performed to treat the healthy and delayed ovulation cows, with PGF2a for estrus synchronization treatment. The treatment effect, synchronous estrus and conception rates were observed and analyzed. [Results] The synchronous estrus and conception rates were improved, after treatment for healthy and delayed ovulation cows. The result showed that LRH-A3 treatment has a better effect. [Conclusion] Injection of LRH-A3 may increase the synchronous estrus and conception rates of cows. |
