Agri-Environmental Indicators - Livestock

The Livestock Patterns domain of the FAOSTAT Agri-Environmental Indicators contains data on livestock numbers, shares of major livestock species and livestock densities in the agricultural area. Values are calculated using Livestock Units (LSU), which facilitate aggregating information for different livestock types. Data are available by country, with global coverage, for the period 1961–2014. This methodology applies the LSU coefficients reported in the "Guidelines for the preparation of livestock sector reviews" (FAO, 2011). From this publication, LSU coefficients are computed by livestock type and by country. The reference unit used for the calculation of livestock units (=1 LSU) is the grazing equivalent of one adult dairy cow producing 3000 kg of milk annually, fed without additional concentrated foodstuffs. FAOSTAT agri-environmental indicators on livestock patterns closely follow the structure of the indicators in EUROSTAT.

FAOSTAT农业环境指标（Agri-Environmental Indicators）中的畜禽格局（Livestock Patterns）领域，收录了农业区域内的畜禽存栏量、主要畜禽品种占比以及畜禽养殖密度相关数据。所有数据均采用畜禽当量单位（Livestock Units, LSU）进行核算，该单位可实现不同畜禽类型的信息标准化汇总。该数据集按国家维度发布，覆盖全球范围，时间跨度为1961年至2014年。本数据集的核算方法采用了《畜禽产业评估报告编制指南》（Guidelines for the preparation of livestock sector reviews，FAO, 2011）中公布的畜禽当量系数。该指南明确，畜禽当量系数需按畜禽类型与国家维度分别计算。畜禽当量单位（即1 LSU）的参考基准为：年产出3000千克牛奶且无需额外饲喂浓缩饲料的成年奶牛的放牧当量。FAOSTAT畜禽格局类农业环境指标的指标框架，严格参照欧盟统计局（EUROSTAT）的同类指标体系设置。
