摘要
背景介绍斗鸡品种在泰国具有重要的历史和文化地位。Lueng Hang Khao（LHK）和 Pradu Hang Dam（PDH）等品种以其令人印象深刻的羽毛和独特的肉质而闻名，这表明它们是为斗鸡和其他目的而选育的。然而，有关泰国本土和当地斗鸡遗传多样性和聚类的信息尚不清楚：调查泰国斗鸡品种的遗传多样性和分化情况，包括用于斗鸡、观赏和食用的种群：方法：使用 28 个微卫星位点进行基因分型，对泰国斗鸡品种（包括 LHK 和 PDH 鸡）进行分析。将数据与 "暹罗鸡生物资源项目 "的基因库进行比较，以了解人类选择对基因分化的影响。不同品种的斗鸡品系可能因共同的育种目标而聚集在一起：结果：对多个鸡种的分析表明，人为选择和遗传漂变导致了亚群分化，影响了遗传景观，造成了遗传搭便车现象。28 个微卫星位点中有 11 个出现了搭便车选择，表明斗鸡存在定向选择。此外，分析表明，泰国斗鸡的基因库中存在与国内鸡种的混杂，而红色丛林鸡的影响微乎其微。这些发现为斗鸡的品种改良、选育策略、遗传资源管理和保持遗传多样性提供了参考：对泰国斗鸡品种的分析表明，利用率与亚群分化之间存在相关性。具体来说，对斗鸡和观赏性特征的选择似乎可以解释这些品种中观察到的遗传结构。
Background: Fighting cock breeds have considerable historical and cultural place in Thailand. Breeds such as Lueng Hang Khao (LHK) and Pradu Hang Dam (PDH) are known for their impressive plumage and unique meat quality, suggesting selection for fighting and other purposes. However, information regarding the genetic diversity and clustering in indigenous and local Thai chickens used for cockfighting is unclear.
Objective: To investigates the genetic diversity and differentiation in Thai fighting cock breeds, including populations for cockfighting, ornamental aspects, and consumption.
Methods: Thai fighting cook breeds, including LHK and PDH chickens were analyzed using genotyping with 28 microsatellite loci. Data were compared to a gene pool library from "The Siam Chicken Bioresource Project" to understand the impact of human selection on genetic differentiation. Fighting cock strains from different breeds may cluster owing to shared breeding goals.
Result: The analysis of several chicken breeds showed subpopulation differentiation driven by artificial selection and genetic drift, affecting the genetic landscape and causing genetic hitchhiking. Eleven of 28 microsatellite loci showed hitchhiking selection, indicating directional selection in fighting cocks. Additionally, analyses revealed admixture with domestic chicken breeds and minimal influence of red junglefowl in the gene pool of Thai fighting chickens. These findings inform breed improvement, selection strategies, genetic resource management, and maintaining genetic diversity in fighting cocks.
Conclusion: Analysis of Thai Fighting chicken breeds revealed a correlation between utilization and subpopulation differentiation. Specifically, selection for cockfighting and ornamental traits appears to explain the observed genetic structure within these breeds.
