Originating in Thailand, the Thai Ridgeback dog is known for its unique fur ridge that grows in the opposite direction along its back. Selective breeding and a limited populations in Thailand have led to significant close inbreeding among related individuals. The current Thai Ridgeback population is assumed to have experienced a loss of genetic diversity and bottleneck events. Furthermore, studies on the genetic diversity and structure of Thai Ridgeback dogs are limited. Therefore, the aim of this study was to assess the genetic diversity in Thai Ridgeback dogs. Microsatellite genotyping and mitochondrial DNA D-loop sequences were used to assess genetic diversity in 105 Thai Ridgeback dogs from various farms throughout Thailand. Significant genetic diversity and minimal inbreeding were observed in the current Thai Ridgeback population. Signs of bottlenecks were not observed because the exchange of genetic material among Thai Ridgeback owners effectively preserved the genetic diversity. Moreover, the genetic parameters in this study supported owner-to-owner exchanges animals for mating programs. To sustain the genetic diversity of Thai Ridgeback dogs, the use of genetic parameters to manage genetic closeness while preserving breed characteristics is essential. These data are crucial for ensuring demographic stability, which is pivotal for long-term conservation and effective population management.
泰国脊背犬起源于泰国，以其沿着背部向相反方向生长的独特毛脊而闻名。泰国的选择性育种和有限的种群数量导致相关个体之间出现了严重的近亲繁殖。目前的泰国脊背犬种群被认为经历了遗传多样性的丧失和瓶颈事件。此外，对泰国脊背犬遗传多样性和结构的研究有限。因此，本研究的目的是评估泰国脊背犬的遗传多样性。利用微卫星基因分型和线粒体DNA D-loop序列对来自泰国各地不同犬舍的105只泰国脊背犬的遗传多样性进行了评估。在当前的泰国脊背犬种群中观察到了显著的遗传多样性和最小程度的近亲繁殖。未观察到瓶颈迹象，因为泰国脊背犬主人之间的遗传物质交换有效地保留了遗传多样性。此外，本研究中的遗传参数支持主人之间交换动物用于繁殖计划。为了维持泰国脊背犬的遗传多样性，利用遗传参数来管理遗传亲缘关系同时保留品种特征至关重要。这些数据对于确保种群稳定性至关重要，而种群稳定性对于长期保护和有效的种群管理至关重要。
