High‐resolution genomic analysis of four local Vietnamese chicken breeds

Abstract

Vietnam is an agricultural country, with 70% of the human population living in rural areas (Desvaux, Vu Dinh, Phan Dang, & Pham Thi, 2008). In these areas, nearly 50%-90% of households own livestock (Burgos, Hong Hanh, Roland-Holst, & Burgos, 2007). Moreover, according to Ngoc (2020), approximately 7,864,700 households raised poultry in 2019. Local chickens in Vietnam account for over 70% of the national poultry population (Lan Phuong, Dong Xuan, & Szalay, 2015). There are 21 local chicken breeds, of which Ri, Tau Vang, Mia, Dong Tao and Ho are the most popular and historical breeds in specific regions (Pham Cong, 2016). Although these breeds are abundant, their productivity is low. Moreover, to meet consumer demand, livestock

High-density single nucleotide polymorphism markers reveal the population structure of 2 local chicken genetic resources

“…The diversity indices in the 2 local populations were quite similar to the range reported for Italian ( Strillacci et al, 2017 ; Cendron et al, 2020 ), European ( Malomane et al, 2019 ), and other native chicken populations ( Evelyne et al, 2022 ; Yuan et al, 2022 ; Wang et al, 2023 ). However, the values differed from the results of a previous study ( Cendron et al, 2020 ), in which the authors reported lower values of heterozygosity and higher values of inbreeding for Cornuta di Sicilia and Val Platani populations.…”

“…The evaluation of local genetic resources involves records of phenotypes, the investigation of their breeding history, as well as the study of genetic variability both within and between populations ( Wimmers et al, 2000 ). Population genetic analyses can help explain the evolutionary history of these animals, clarify the origin and differentiation of populations, and assist in genetic breeding ( Elbeltagy et al, 2016 ; Fleming et al, 2016 ; Cendron et al, 2020 ; Evelyne et al, 2022 ).…”

Genetic diversity and breed identification of Chinese and Vietnamese local chicken breeds based on microsatellite analysis

“…Previous studies have drawn similar conclusions ( Cuc et al, 2010 ), while Vietnamese chicken breeds could be better separated at higher K values. The divergence of Vietnamese chicken breeds is closely related to their geographical distribution ( Evelyne et al, 2022 ). Northern chicken breeds comprise an unstructured gene pool, and differentiation of Vietnamese chicken breeds can be observed between the northern and south-central coasts, as well as the Mekong Delta ( Cuc et al, 2010 ).…”
