| 摘 要： | 近几年来，我国肉牛生产发展很快，但生产水平较低，平均产肉率不高，其中一个重要原因是迄今我国还没有一个自己培育的专门化肉牛品种。要大力发展我国的肉牛生产，除了利用国外优秀的肉牛品种杂交改良我国地方黄牛外，还必须培育自己的肉牛品种。本文从社会经济发展，人民生活水平和市场变化入手，对秦川牛作了评价，回顾了它的选育历史，指出了现时期秦川牛肉用选育方向的紧迫性。在分析了秦川牛的优点及其与国外著名肉牛品种相比存在的缺点和不足的基础上，提出秦川牛选育的主要目标和采取的技术措施，包括选择和建立核心群、建立健全秦川牛的选育体系、建立选育协作组、开展联合育种、导入适当外血和利用分子生物学技术，加快秦川肉牛的分子育种等，以早日培育出秦川肉牛新品系，使所形成的秦川肉牛新品系，在秦川牛现有经济类型的基础上得到提升与改造，适应经济发展需要，促进肉牛产业化发展。这对农村产业结构优化、社会经济发展和农民致富将产生广泛而深远的影响。

| Abstract: | In last few years, beef production in China has been developing quickly, but beef production level and beef percentage per cattle are still very low, one of the main reasons is that no special beef breed has been bred in China beef industry by now. In order to develop beef industry rapidly, besides we can utilize foreign beef breeds to improve our indigenous yellow cattle, we must breed our own beef breeds. In this contribution, based on the development of China economy and society, the changing of living conditions of Chinese people and the market needs, Qinchuan cattle is evaluated again and its breeding and selection history are introduced, the direction of selection and breeding put forward. According to the comparison of the advantage and disadvantage of Qinchuan cattle with foreign beef breeds, main aims of selection and breeding of Qinchuan cattle and the technical measures, including establishment of core population and breeding and selection system, the foundation of the breeding cooperation groups and united breeding measures and application of modern molecular breeding technology in Chinese beef breeding are also presented, which will help to breed a new Qinchuan beef line as soon as possible and finally meet the need of our beef industrialization and economy development, all of them will bring some far reaching effects on optimization of rural industry structure, economy and society development and farmer affluence. |
