Abstract: This paper delved into the application of Buserelin in timed artificial insemination （TAI） protocols for dairy cattle,while also elaborating on strategies for improving conception rates and its use in treating ovarian disorders. Additionally,a comparative analysis is conducted between Buserelin and Gonadorelin,highlighting their functional differences,mechanisms of action,and respective advantages in applicable scenarios thereby revealing the unique role and value of Buserelin in dairy cattle reproduction. Through extensive and rigorous field trial data,this study evaluated the practical efficacy of Buserelin. Furthermore it explored the potential impact of this product on early pregnancy embryo loss in dairy cows,integrating other reproductive technologies to mitigate the risk of early embryonic loss and enhance reproductive efficiency and economic benefits. By providing an in-depth analysis of Buserelin’s pharmacological mechanisms and empirical research on its practical application in dairy reproduction,this paper aimed to offer scientifically sound methods and strategies for efficient breeding in the dairy industry,promoting more scientific,efficient,and sustainable development in dairy farming.

Key words: Buserelin, timed artificial insemination, early embryonic death, reproductive efficiency improvement
