At present,the domestic beef cattle industry is developing rapidly,and it is urgent to improve the breeding efficiency and beef cattle quality.Somatic cell nuclear transfer(SCNT),as an advanced reproductive biotechnology,plays a key role in promoting the development of beef cattle genetics and breeding.In this paper,the principle of SCNT and its application in beef cattle breeding at home and abroad were analyzed in detail,and its progress and significant advantages in improving genetic quality were dis-cussed.At the same time,the challenges of low operation efficiency,low embryo survival rate and abnormal development of recon-structed embryos faced by SCNT were analyzed,which limited the wide application of SCNT technology in beef cattle breeding.Looking forward to the future,it is necessary to continuously improve SCNT technology,improve cloning efficiency and survival rate,and explore the integration with emerging technologies such as gene editing to accelerate the progress of beef cattle genetic breeding.
