我国奶牛生产性能测定技术（DHI）从1992年发展至今,已有30 年的历程。在这30 年里,国内DHI已趋于完善,不过从运行现状来看依然存在人员稀少、报告应用不足、测定设备落后等问题。本文剖析了DHI技术的发展情况,并指出我国DHI在人员队伍、测定报告应用以及设备更新上需要完善等问题,据此提出补充队伍人数、扩宽报告应用范围、更换硬件设备等建议,为国内DHI更加合理的发展奠定基础。

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the current situation,there are still problems such as scarcity of personnel,insufficient reporting and application,and outdated measuring equipment.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.
