In order to accomplish the dairy cow tuberculosis eradication project in Tianjin,the technology standards for bovine tuberculosis eradication in dairy cow were developed in combination with traditional technical measures, such as detection,culling,disinfection,quarantine,epidemiological investigation and supervision. The implementa-tion schemes were worked out according to the actual bovine tuberculosis situation in Tianjin,and the scientiifc and feasible technical route was determined by eradication of the disease in county(district) as a unit. During the past four years,0.713 million dairy cows were detected and 170 of them was positive,and the number of positive cows was reduced year by year. In 2013,no positive dairy cow was detected and all the counties with agriculture met the bovine tuberculosis freedom standard issued by Ministry of Agriculture and get through the examination conducted by Tianjin Animal Husbandry and Veterinary Bureau. This article analyzes and discusses the implementation process and the suc-cessful experiences,hoping to provide advices on dairy cow tuberculosis eradication.%为完成奶牛结核病净化工程，天津市引进了γ-干扰素检测新技术，结合传统的检测、扑杀、消毒、检疫、流调、监管等技术措施，制定了奶牛结核病净化技术规范。根据本市奶牛结核病防治实际情况，制定了全市奶牛结核病净化项目实施方案，确定了科学的可行的以区县为单位分区实施的净化技术路线。通过4年的努力，全市共完成奶牛结核病检测71.3万头次，检出阳性牛170头，且阳性牛呈逐年下降趋势，2013年无阳性牛检出。至2013年底，全市所有农业区县均达到农业部颁布的奶牛结核病净化标准，并通过市畜牧兽医局组织的考核验收。本文对项目实施过程及成功经验进行了分析和探讨，以期为其它地区开展奶牛结核病净化工作提供参考。
