Abstract

Ethiopia has a large and diverse population of small ruminants, which contribute substantially to the livelihood and income of the rural poor and the country at large. However, the sector faces a number of challenges. Productivity per animal and flock offtake are both very low. Reasons attributed for the apparent low productivity are as follows: absence of appropriate breeding programmes, lack of technical capacity, inadequate and poor-quality feeds, diseases leading to high lamb mortality, and underdeveloped markets in terms of infrastructure and information. Historically, sheep and goats have received little policy or investment attention. Genetic improvement of small ruminants could contribute to bridging the productivity gap. In the past, the government of Ethiopia has placed much emphasis on importing exotic genetics and cross-breeding with local stock as a strategy for genetic improvement. However, this has not led to a significant productivity improvement and the programmes have generally been unsustainable. Currently, there is a change in approach and a recognition of the need to focus genetic improvement efforts on the local genetic resources that are well adapted to the diverse agro-ecologies and production environments in the country. Community-based breeding programmes (CBBPs), which focus on indigenous stock and consider farmers' needs, views, decisions and active participation, from inception through to implementation, have been identified as programmes of choice. The Ethiopian government and the private sector need to invest in strategic areas around CBBPs to make the programme work for the poor and be sustainable in low-input systems.

摘要

埃塞俄比亚拥有大量多样化的小反刍动物种群,这些动物对农村贫困人口和整个国家的生计和收入做出了重大贡献。然而,该行业面临着许多挑战。单只动物和畜群的生产力都非常低。造成明显低生产力的原因如下:缺乏适当的繁殖计划、缺乏技术能力、饲料不足且质量差、导致羔羊死亡率高的疾病,以及基础设施和信息方面不发达的市场。从历史上看,羊和山羊很少受到政策或投资的关注。小反刍动物的遗传改良可以有助于缩小生产力差距。过去,埃塞俄比亚政府非常重视进口外来遗传物质并与当地品种进行杂交,以此作为遗传改良的策略。然而,这并没有带来生产力的显著提高,而且这些计划通常都无法持续。目前,埃塞俄比亚政府改变了方法,认识到需要将遗传改良工作重点放在适应该国多样化农业生态和生产环境的本地遗传资源上。以社区为基础的繁殖计划(CBBP)已经被确定为首选计划,这些计划专注于本地品种,并考虑到农民的需求、观点、决策和积极参与,从开始到实施。埃塞俄比亚政府和私营部门需要在 CBBP 周围的战略领域进行投资,以使该计划能够为贫困人口服务,并在低投入系统中具有可持续性。
