Combined QTL Map of Dairy Cattle Traits

2021-09-01: repository is offline Background: Many studies have been conducted to detect quantitative trait loci (QTL) in dairy cattle. However, these studies are diverse in terms of their differing resource populations, marker maps, phenotypes, etc, and one of the challenges is to be able to synthesise this diverse information. This web page has been constructed to provide an accessible database of studies, providing a summary of each study, facilitating an easier comparison across studies. However, it also highlights the need for uniform reporting of results of studies, to facilitate more direct comparisons being made. Description: Studies recorded in this database include complete and partial genome scans, single chromosome scans, as well as fine mapping studies, and contain all known reports that were published in peer-reviewed journals and readily available conference proceedings, initially up to April 2005. However, this data base is being added to, as indicated by the last web update. Note that some duplication of results will occur, in that there may be a number of reports on the same resource population, but utilising different marker densities or different statistical methodologies. The traits recorded in this map are milk yield, milk composition (protein yield, protein %, fat yield, fat %), and somatic cell score (SCS).

2021年9月1日：数据仓库已离线。背景：众多研究致力于检测乳牛的定量性状位点（QTL）。然而，这些研究在资源群体、标记图谱、表型等方面存在多样性，其中一个挑战在于如何综合这些多样化的信息。本网页旨在构建一个易于访问的研究数据库，提供每项研究的摘要，便于跨研究进行比较。然而，它也强调了统一报告研究结果的必要性，以促进更直接的比较。描述：数据库中记录的研究包括完整的基因组扫描、单染色体扫描以及精细定位研究，并包含所有已发表在同行评审期刊和易于获取的会议论文集中的已知报告，最初截止至2005年4月。然而，正如最后网页更新所示，数据库仍在不断补充。请注意，可能会出现结果重复的情况，即在相同的资源群体上可能会有多个报告，但使用不同的标记密度或不同的统计方法。该图谱记录的性状包括产奶量、奶成分（蛋白质产量、蛋白质百分比、脂肪产量、脂肪百分比）以及体细胞评分（SCS）。
