生产性能测定（DHI）在现代奶牛养殖中发挥着重要的作用，而参测群体的群体结构以及DHI原始数据的准确性又对测定结果有很大的影响，并进而通过DHI最终影响奶牛养殖管理方面的分析与改进。本文通过分析近几年北京地区中小型牛场参测DHI的基本情况，旨在得出北京地区除三元集团外其他中小型牛场的DHI现状，为北京地区奶牛DHI管理提供依据。

Dairy Herd Improvement (DHI) plays an important role in modern dairy farming, the structure of testing group and the accuracy of DHI raw data have a great inlfuence on the measurement results, and whatsmore, inlfuence the analysis and improvement in dairy management. In this article, through analysing the basic situation of DHI data of cows in recent years in Beijing, we designed to draw the status of DHI except the Sanyuan group in Beijing. In this case, we can provide the basis management for measurement of DHI in Beijing area.
