Abstract: China's dairy cow performance measurement technology （DHI） has been developed for 30 years since 1992. In the past 30 years,China's DHI has become more and more perfect,but from the current situation,there are still problems such as scarcity of personnel,insufficient reporting and application,and outdated measuring equipment. This paper analyzed the development of DHI technology,and pointed out that China DHI need to improve in terms of personnel team, measurement report application and equipment update. Based on this,it put forward suggestions to strengthen DHI,such as replenishing the number of teams,expanding the scope of report application and replacing hardware equipment,laying the foundation for the rational use of domestic DHI.
