Bangladeshi indigenous chicken varieties - Common Deshi, Hilly and Naked Neck are notable for their egg production, meat quality, extraordinary survivability and disease resistance. However, the potential to harness their unique genetic merits are being eroded by various factors, including crossbreeding. In-depth genomic studies have not been carried out on these breeds so far. To this end, blood samples and associated phenotypic metadata have been collected from local, unimproved birds sampled from 8 different locations across the country, and from Bangladesh Livestock Research Institute (BLRI)-improved chickens of the same mentioned breeds. Whole Genome Sequencing (WGS) of 96 selected samples, representing local and improved populations of each breed, has been carried out. Around 22 M high-quality SNPs have been identified, with 25% of these being novel variants previously undescribed in public databases. This data set will allow for genetic comparison between breeds, and between selected and unimproved birds, providing a resource for genomic selection in Bangladeshi breeding schemes to create more productive and resilient poultry stock.
孟加拉国本土鸡品种——普通德希鸡、山地鸡和裸颈鸡,以其产蛋量、肉质、超强的生存能力和抗病能力而闻名。然而,包括杂交在内的各种因素正在侵蚀利用它们独特遗传优势的潜力。到目前为止,尚未对这些品种进行深入的基因组研究。为此,已从该国8个不同地点采集的当地未经改良的鸡以及孟加拉国畜牧研究所(BLRI)改良的上述品种鸡中收集了血液样本和相关的表型元数据。已对96个选定样本进行了全基因组测序(WGS),这些样本代表了每个品种的当地和改良群体。已鉴定出约2200万个高质量单核苷酸多态性(SNP),其中25%是公共数据库中以前未描述的新变体。该数据集将允许对品种之间以及选定鸡和未改良鸡之间进行遗传比较,为孟加拉国育种计划中的基因组选择提供资源,以培育出更具生产力和适应力的家禽种群。
