The objective of this study was to review the current status of genetic evaluation systems for production and functional traits as practiced in different Interbull member countries and to discuss that status in relation to research results and potential improvements. Thirty-one countries provided information. Substantial variation was evident for number of traits considered per country, trait definition, genetic evaluation procedure within trait, effects included, and how these were treated in genetic evaluation models. All countries lacked genetic evaluations for one or more economically important traits. Improvement in the genetic evaluation models, especially for many functional traits, could be achieved by closing the gaps between research and practice. More detailed and up to date information about national genetic evaluation systems for traits in different countries is available at www.interbull.org. Female fertility and workability traits were considered in many countries and could be next in line for international genetic evaluations.
本研究的目的是回顾不同国际公牛组织成员国目前用于生产性状和功能性状的遗传评估系统的现状，并结合研究结果和潜在改进措施来讨论这一现状。31个国家提供了信息。各国在考虑的性状数量、性状定义、性状内的遗传评估程序、纳入的效应以及这些效应在遗传评估模型中的处理方式等方面存在显著差异。所有国家都缺乏对一种或多种经济上重要性状的遗传评估。通过弥合研究与实践之间的差距，可以改进遗传评估模型，特别是对于许多功能性状。有关不同国家性状的国家遗传评估系统的更详细和最新信息可在www.interbull.org上获取。许多国家都考虑了雌性生育力和可操作性性状，这些性状可能是下一批进行国际遗传评估的对象。
