Ex situ and in situ data for endangered livestock breeds in Spain

Improvements in ex situ storage of genetic and reproductive materials offer an alternative for endangered livestock breed conservation. This is a dataset for current ex situ collections and in situ population for 179 Spanish livestock breeds of seven species, cattle, sheep, pig, chicken, goat, horse and donkey. Ex situ data was obtained via survey administered to 18 functioning gene banks in Spain and relates to the reproductive genetic materials (semen doses) of 211 livestock breeds distributed across the gene banks. In situ data combines CENSUS information with linear regression techniques and relates to the geographic distribution of 179 Spanish autochthonous livestock breeds (2009-2018), and in situ population projections and extinction probabilities (2019-2060). We use a decision variable defining an “acceptable level of risk” that allows decision makers to specify tolerable levels of in situ breed endangerment when taking ex situ collection and storage decisions.

对遗传和繁殖材料离体储存技术的改进，为濒危家畜品种的保存提供了替代方案。本数据集收录了179种西班牙家畜品种（包括牛、羊、猪、鸡、山羊、马和驴）的现时离体收藏和原位种群信息。离体数据通过在西班牙18个运营中的基因库进行的调查获得，并涉及分布在这些基因库中的211种家畜品种的繁殖遗传材料（精子剂量）。原位数据结合了人口普查信息与线性回归技术，并关联至179种西班牙本土家畜品种的地理分布（2009-2018年），以及原位种群预测和灭绝概率（2019-2060年）。我们采用一个定义“可接受风险水平”的决策变量，使决策者能够在做出离体收藏和储存决策时，指定可容忍的原位品种濒危程度。
