Our aim was to identify elements useful in designing policies and programmes for conservation of farm animal genetic resources, taking as case study a group of European local cattle breeds. We first investigated the implications of differences among countries in the policies and programmes to be developed. Secondly, we analysed key elements common to countries, which may affect local breed viability. We used the herd size trend expected by the farmer in the near future as an indicator of breed viability. Fifteen breeds, for a total of 355 farms, were surveyed. To take into account the multiple factors influencing breeds' demographic trends, the questionnaire included economical, technical and social aspects. Among the major differences across countries was the perception of the farmer on the value attributed to the local breed by society. Concerning the elements common to countries and their association to breed viability, the greater the collaboration among farmers and the stakeholders' appreciation as perceived by the farmer, the greater the viability of the farm. An opposite trend was observed for the age of the farmer. Older farmers generally planned to soon cease farming or decrease herd size, whereas young farmers planned to increase the size of their herds. Implications of including these elements in conservation policies are discussed.
我们的目的是确定在制定保护农场动物遗传资源的政策和计划时有用的要素,以欧洲地方牛品种群作为案例研究。我们首先研究了各国之间有待制定的政策和计划之间的差异所带来的影响。其次,我们分析了对各国可能影响地方品种生存能力的共同关键要素。我们使用农民在不久的将来预期的畜群规模趋势作为品种生存能力的指标。对 15 个品种的 355 个农场进行了调查。为了考虑影响品种人口趋势的多个因素,问卷包括经济、技术和社会方面。各国之间的主要差异之一是农民对社会赋予本地品种的价值的看法。关于各国共同的要素及其与品种生存能力的关联,农民之间的合作以及农民感知到的利益相关者的赞赏程度越高,农场的生存能力就越强。农民的年龄则呈现出相反的趋势。年龄较大的农民通常计划很快停止养殖或减少畜群规模,而年轻的农民则计划增加畜群规模。讨论了将这些要素纳入保护政策的影响。
