摘要
肉牛发展继奶牛产业发展热之后,再次进入陕西省产业发展规划之列,为肉牛业的发展提供了良好机遇。但是,作为陕西省肉牛产业的发展的先决条件和改良基础的种质资源存在品种少、数量少、遗传改良无序和人工授精覆盖率低等问题,成为制约陕西省肉牛产业发展之瓶颈。本文在分析陕西省肉牛种质资源现状的基础上,指出肉牛改良种质资源在利用方面存在的问题,并提出陕西省肉牛改良种质资源利用的对策,以期为陕西省肉牛产业的健康、持续和稳定发展提供参考。
Following the hot development of dairy cattle industry, the development of beef cattle is put on the agenda,providing a good opportunity to the development of beef cattle industry. However, as the prerequisite and base of improvement for the development of beef cattle industry in Shaanxi province, there are many problems in gerplasm resources. Lack of species and number, disordered genetic improvement, low coverage in artificial insemination and so on, have hit a bottleneck which restricts the development of beef cattle industry. Based on the analysis of present situation of beef cattle gerplasm resources, the prob- lems of utilization in the improvement of beef cattle germplasm resource were indicated in thrs paper. The countermeasures for the utilization in the improvement of beef cattle germplasm resources were proposed. The aim of this paper is to provide a reference for developing beef cattle industry healthily, sustainablely and stably.
