Supplementary material of: Impact of genomic selection on genetic diversity in 5 local European cattle breeds.

This paper investigates the impact of genomic selection on genetic diveristy of five local cattle breeds from three European countries. The five breeds evaluated are Meuse Rhine Yssel (MRY; from the Netherlands), Norwegian Red (from Norway), Abondance, Tarentaise, and Vosgienne (from France). We investigated changes in population demographic structure, as well as trends and rates of kinship and inbreeding, using both pedigree- and genomic-based measures. The population size varied depending on the breed, with Vosgienne being the smallest and Norwegian Red being the largest. Single nucleotide polymorphisms (SNPs) genotypes were available for 4,645 MRY, 193,489 Norwegian Red, 16,387 Abondance, 8,578 Tarentaise, and 4,472 Vosgienne animals. Animals were genotyped with more than 40,000 SNPs. For a detail description please refer to the full paper.

本研究探讨了基因组选择对来自三个欧洲国家的五个地方牛品种遗传多样性的影响。本次评估的五个品种分别为：默兹-莱茵-艾瑟尔牛（Meuse Rhine Yssel，缩写MRY，源自荷兰）、挪威红牛（源自挪威）、阿邦当斯牛、塔朗泰斯牛以及沃吉耶牛（源自法国）。本研究基于系谱和基因组两种分析方法，探究了种群统计结构的变化，以及亲缘关系与近交的趋势和速率。各品种的种群规模各不相同，其中沃吉耶牛种群规模最小，挪威红牛种群规模最大。本研究共获得4645头默兹-莱茵-艾瑟尔牛、193489头挪威红牛、16387头阿邦当斯牛、8578头塔朗泰斯牛以及4472头沃吉耶牛的单核苷酸多态性（Single Nucleotide Polymorphisms，SNPs）基因型数据。所有受试个体均通过搭载超过4万个SNPs的基因分型芯片完成基因分型。如需获取详细描述，请参阅完整论文。
