北方非传统肉牛养殖区品种改良方案

在目前全国各地肉牛产业飞速发展的形势下,北方非传统肉牛养殖区也开始将产业重点向肉牛养殖业调整。对北方非传统肉牛养殖区的生态环境、肉牛品种、饲养管理、产业发展和肉牛交易等特点进行了分析。在该基础上,因地制宜地提出北方非传统肉牛养殖区肉牛品种改良方案。该方案分为2个阶段实施,第1阶段为基础母牛安格斯化：利用红安格斯牛作为父本,对当地黄牛进行杂交改良,实现基础母牛群体安格斯化;第2阶段为两品种轮回杂交：选用另一专门化肉牛品种与红安格斯牛为主要父本品种,开展两品种轮回杂交,建立优质肉牛高效繁育技术体系。通过制定该技术方案,以期为北方非传统肉牛养殖区开展黄牛改良和发展特色经济提供技术指导。

Variety Improvement Program for Non-traditional Beef Cattle Farming Area in Northern Inner Mongolia

Under the background of rapid development of beef cattle industry in China, the non-traditional beef cattle farming areas in northern Inner Mongolia have also begun to adjust their industrial focus to the beef cattle farming industry. The characteristics of ecological environment, beef cattle varieties, feeding management, industrial development and beef cattle trading in non-traditional beef cattle farming areas in northern Inner Mongolia were analyzed. On this basis, the variety improvement plan of beef cattle in non-traditional beef cattle farming areas was proposed according to the local conditions. The implementation of this program was composed of two phases. The first stage was to improve the offspring （breedable cows） of the local yellow cattle by crossbreeding using red Angus cattle as the male parent. The second stage was the rotational crossing using red Angus cattle and another specialized beef cattle variety as the main male parent to establish a breeding technology system for production of high-quality beef cattle. The program established in this study may help to provide technical guidance for the variety improvement of the yellow cattle and the development of the characteristic economy for non-traditional beef cattle farming areas in northern Inner Mongolia.
