Asia with over half the population in the world has a thriving agriculture, a large part of which is devoted to pig production. The efficiency of production varies from country to country and is largely the legacy of whether the country relies on backyard farms using native breeds or intensive commercial farms using genetically improved breeds from Europe and North America. Reproductive efficiency is not as advanced as in Europe and this is the result of climatic conditions, which are hot and humid, the presence of most pig diseases, substandard management, the difficulty of obtaining quality feeds and appropriate delivery systems and the reliance on native breeds which are far less prolific than European ones. Improvements can only occur if investments are made in housing, cooling systems, disease control, management, quality feeds and better genetics.
亚洲拥有世界一半以上的人口,其农业蓬勃发展,其中很大一部分致力于生猪生产。各国的生产效率各不相同,这在很大程度上取决于该国是依赖使用本地品种的后院农场,还是依赖使用来自欧洲和北美的基因改良品种的集约化商业农场。繁殖效率不如欧洲先进,这是气候条件(炎热潮湿)、大多数猪病的存在、管理不达标、难以获得优质饲料和适当的供应系统以及依赖远不如欧洲品种多产的本地品种的结果。只有在住房、冷却系统、疾病控制、管理、优质饲料和更好的基因方面进行投资,才会有所改善。
