“…Chee Fah chickens weigh 891-1714 g at 16 weeks and produce between 43 and 124 eggs annually, whereas Fah Luang chickens weigh 917-1311 g at 16 weeks and produce up to 141 eggs per year. The market prices of the eggs and meat of these chicken breeds are relatively higher than those of commercial breeds [18], while the costs of Chee Fah and Fah Luang chickens and their products are lower than those of commercial varieties in remote highlands, such as in Chiang Rai, and fills a specific niche for the local people [20]. The Chee Fah and Fah Luang chickens have adapted to the low-temperature highland environment in Northern Thailand, whereas broiler and layer chickens struggle to grow under the same conditions [21].…”

Knowledge of the genetic characteristics, origin, and local adaptation of chickens is essential to identify the traits required for chicken breeding programs. Chee Fah and Fah Luang are black-boned chicken breeds reared in Chiang Rai, Thailand. Chickens are an important part of the local economy and socio-culture; however, the genetic diversity, characteristics, and origins of these two breeds have been poorly studied. Here, we investigated the genetic diversity, gene pool, and origin of the Chee Fah and Fah Luang chickens using mitochondrial DNA D-loop (mtDNA D-loop) sequencing and microsatellite genotyping, as well as habitat suitability analysis using maximum entropy modeling. The MtDNA D-loop sequencing and microsatellite genotype analyses indicated that the Chee Fah and Fah Luang chickens shared haplogroups A, B, and CD with Chinese black-boned chickens. Gene pool analysis revealed that the Chee Fah and Fah Luang chickens have distinct genetic patterns compared to Thai domestic chickens and red junglefowl. Some gene pools of red junglefowl and other Thai domestic chickens were observed within the Chee Fah and Fah Luang chicken gene pool structures, suggesting genetic exchange. The data indicate that the Chee Fah and Fah Luang chickens originated from Chinese indigenous black-boned chicken breeds and experienced crossbreeding/hybridization and introgression with red junglefowl and other domestic breeds during domestication. Interestingly, the Chee Fah and Fah Luang chickens from Chiang Rai shared the same allelic gene pool, which was not shared with the Chee Fah and Fah Luang chickens from Mae Hong Son, suggesting at least two gene pool origins in the Chee Fah and Fah Luang chicken populations. Alternatively, different gene pools in the Chee Fah and Fah Luang chickens from different localities might be caused by differences in environmental factors, especially elevation.
