摘　　要：通过调研西北5省农区的奶牛养殖现状,收集有关遗传改良和生产性能数据资料,并加以统计分析,讨论了西北农区奶牛遗传改良工作中现存问题,认为奶牛DHI测定体系对奶牛养殖的生产与管理具有重要意义,提出了今后发展与完善奶牛遗传改良工作和DHI测定体系的建议和措施,为进一步加快西北5省农区奶牛遗传改良工作和提高奶牛生产性能水平,提供了一定的参考价值。The author researched the present agricultural areas in the five northwest provinces on the present situation of Chinese dairy industry development, and collected related data of genetic improvement and production performance measurement, which were statisticed and analyzed. Discussing the existing problems of genetic improvement in the five northwest provinces, so people could conclude that DHI measurement system were significant to the cattle breeding production and management, and propose several advices to improve and perfect the genetic improvement and DHI measurement system, and also provide some value information for further speeding up of the dairy improvement in the farming areas of five northwest provinces.
