摘要

在发展中国家资源贫乏的小农生产者的环境中,动物遗传改良战略的转让并不成功。因此,农民很难或根本不可能获得具有高遗传潜力的动物来源。随着生产者改进或加强其系统以抓住市场机会,这种获取机会的需求就更加突出。本文综述了已确定的育种计划转移的制约因素、对新方法的需求以及在应用更有针对性的方法方面获得的经验教训。这些问题和想法来自一个涉及干旱地区国际农业研究中心的工作组的经验;奥地利自然资源与生命科学大学;阿根廷国家农业技术研究所;巴西农业研究公司(Embrapa山羊和绵羊);以及墨西哥国家林业、农业和动物生产研究所。在小农系统中转移育种策略并不是一项简单的任务。与在商业畜牧生产环境中的成功应用相比,在小农系统中实现主要目标需要一种超越纯技术问题的整体方法。在已查明的与育种计划的执行有直接关系的所有方面中,缺乏具体的国家政策,加上支助改进小农生产系统的长期资金,以及社区缺乏参与和参与,这些问题更倾向于实现可持续性和实现某一育种计划的目标。

Small Ruminant Breeding Plans for Smallholder Systems
The transfer of animal genetic improvement strategies in the environments of resource-poor smallholder producers in developing countries has not been successful. Therefore, the access by farmers to sources of animals with high genetic potential is difficult or just not possible. As producers improve or intensify their systems to capture market opportunities, this access need is accentuated. This paper reviews identified constraints to the transfer of breeding plans, the need for a new approach, and the lessons learned in applying a better-targeted approach. The issues and thoughts were derived from the experience of a working group involving the International Center for Agricultural Research in the Dry Areas; Austrian University of Natural Resources and Life Sciences; Argentinean National Institute of Agriculture Technology; Brazilian Agricultural Research Corporation (Embrapa Goats and Sheep); and National Research Institute for Forestry, Agriculture and Animal Production-Mexico. The transfer of breeding strategies in smallholder systems is not a straightforward task. Contrasting a successful application in commercial livestock production environments, the achievement of the primary objectives in smallholder systems requires a holistic approach beyond pure technical matters. Of all identified aspects with direct incidence in the implementation of breeding plans, the lack of specific national policies coupled with long-term funding to support the improvement of smallholder production systems, and the lack of involvement and participation of the communities emerge as issues that gravitate more to achieve sustainability and meet the objectives of a given breeding plan.
