Abstract

Bawri or Garri, a non-descript cattle population managed under an extensive system in Madhya Pradesh state of India, was identified and characterized both genetically and phenotypically to check whether or not it can be recognised as a breed. The cattle have white and gray colour and are medium sized with 122.5 ± 7.5 cm and 109.45 ± 0.39 cm height at withers in male and female, respectively. Double-digest restriction site associated DNA (ddRAD) sequencing was employed to identify ascertainment bias free SNPs representing the entire genome cost effectively; resulting in calling 1,156,650 high quality SNPs. Observed homozygosity was 0.76, indicating Bawri as a quite unique population. However, the inbreeding coefficient was 0.025, indicating lack of selection. SNPs found here can be used in GWAS and genetic evaluation programs. Considering the uniqueness of Bawri cattle, it can be registered as a breed for its better genetic management.

摘要

巴沃里或加勒里牛是印度中央邦一种未经描述的牛群,以粗放的方式管理,我们从遗传和表型两方面对其进行了鉴定和特征分析,以确定它是否可以被认定为一个品种。该牛群的颜色为白色和灰色,体型中等,公、母牛的体高分别为 122.5±7.5 厘米和 109.45±0.39 厘米。我们采用双酶切相关 DNA(ddRAD)测序技术,以经济高效的方式鉴定整个基因组的无选择偏差的 SNP,结果共鉴定到 115.665 万个高质量 SNP。观察到的杂合度为 0.76,表明巴沃里牛是一个非常独特的群体。然而,近交系数为 0.025,表明缺乏选择。在这里发现的 SNP 可用于 GWAS 和遗传评估计划。考虑到巴沃里牛的独特性,它可以作为一个品种进行登记,以更好地进行遗传管理。
