背景:战斗公鸡品种在泰国具有相当大的历史和文化地位。LuengHangKhao(LHK)和PraduHangDam(PDH)等品种以其令人印象深刻的羽毛和独特的肉质而闻名,建议选择战斗和其他目的。然而,有关用于斗鸡的本地和本地泰国鸡的遗传多样性和聚类的信息尚不清楚。
目的:研究泰国斗鸡品种的遗传多样性和分化,包括斗鸡人口,装饰性方面,和消费。
方法:泰国战斗厨师品种,使用28个微卫星基因座的基因分型分析了包括LHK和PDH的鸡。将数据与“暹罗鸡生物资源项目”的基因库库进行比较,以了解人类选择对遗传分化的影响。由于共同的育种目标,来自不同品种的战斗公鸡菌株可能会聚集。
结果:对几个鸡品种的分析显示,由人工选择和遗传漂移驱动的亚群分化,影响遗传景观并导致遗传搭便车。28个微卫星基因座中有11个显示搭便车选择,指示斗鸡的方向选择。此外,分析显示,与家养鸡品种混合在一起,并且在泰国战鸡的基因库中,红色junglefowl的影响很小。这些发现为品种改进提供了信息,选择策略,遗传资源管理,并在斗鸡中保持遗传多样性。
结论:对泰国斗鸡品种的分析揭示了利用与亚群分化之间的相关性。具体来说,斗鸡和观赏性状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.
RESULTS: 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.
CONCLUSIONS: 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.
