近年来,海原县肉牛产业得到快速发展。为支撑未来肉牛产业发展需求,迫切需要从品种改良技术层面破解当前育种工作中遇到的问题,为今后高端肉牛产业发展指明方向。本文分析了海原县当前繁育母牛资源现状,从肉牛产业发展目标以及制约产业发展的瓶颈问题出发,探索高端肉牛产业的内在含义,提出以西门达尔牛为母本,安格斯公牛为父本的“海原黑牛”育种方向及其在实践基础上的现实可能性。同时通过现有安格斯纯种繁育扩大母牛和选育良种安格斯公牛,为大量杂交提供优秀的公牛基因资源。希望对当前海原肉牛产业发展具有一定指导意义。

Practice and Exploration on Breed Improvement of Haiyuan Beef Cattle in Ningxia

In recent years, the beef cattle industry in Haiyuan county has developed rapidly. In order to support the future development of the beef cattle industry, it is urgent to solve the problems encountered in the current breeding work from the level of product improvement technology, and to point out the direction for the development of the high-end beef cattle industry in the future. This paper analyzes the current status of breeding cow resources in Haiyuan county, starting from the development goal of beef cattle industry and the bottleneck problem restricting industrial development, exploring the inner meaning of high-end beef cattle industry, and proposing Simental cattle as the female parent and Angus Bull as the male parent. The breeding direction of "Haiyuan Black Cattle" and its realistic possibilities based on practice. At the same time, the existing Angus purebred breeding is used to expand the cows and breed the improved Angus bulls, providing excellent bull genetic resources for large numbers of crosses. I hope that it has certain guiding significance for the current development of Haiyuan beef cattle industry.
