Holstein-Friesian (HF) gene bank collections were established in France, the Netherlands, and the United States to conserve genetic diversity for this breed. Genetic diversity of HF collections within and between countries was assessed and compared with active male HF populations in each country by using pedigree data. Measures of genetic diversity such as probability of gene origin inbreeding and kinship were calculated. The cryobanks have captured substantial amounts of genetic diversity for the HF compared with the current populations. A substantial part of the US, French, and Dutch collections seems to be genetically similar. On the other hand, the US collection in particular represents an interesting reservoir of HF genes of the past. Gene banks can play an important role in conserving genetic diversity within livestock breeds over time, and may support industry in the future when needed.
荷斯坦-弗里生（HF）基因库的建立分别在法国、荷兰和美国，旨在保护该品种的遗传多样性。通过系谱数据，评估了国家内部和国家之间 HF 基因库的遗传多样性，并与各国的活跃雄性 HF 群体进行了比较。计算了遗传多样性的度量，如基因起源的概率、近交和亲缘关系。与当前的种群相比，低温库已经为 HF 捕获了大量的遗传多样性。美国、法国和荷兰的基因库的大部分似乎在遗传上是相似的。另一方面，美国的基因库尤其代表了过去 HF 基因的一个有趣的宝库。随着时间的推移，基因库可以在牲畜品种的遗传多样性保护方面发挥重要作用，并在未来需要时为行业提供支持。
