Abstract: [Objective] In order to explore the application of simultaneous estrus technology in large-scale dairy farms.[Method] In this experiment,three different treatments were used for simultaneous estrus treatment of cows 80 days after delivery,and the effects of different treatments on estrus rate and conception rate of cows were compared after the experiment.[Result] The results showed that the estrus rates of test groups A,B and C were 72.50%,80.00% and 87.50%,respectively. The conception rates were 62.07%,65.63% and 68.57%,and the estrus rate of test group C was significantly higher than that of other groups（P<0.05）.[Conclusion] The comprehensive analysis results showed that the promotion of sympathetic estrus technology can greatly improve the economic benefits of dairy cattle breeding,and under the experimental conditions,the estrus effect of the experimental group C was the best in the same period.
