Research data_Water Efficiency in Dairy Farming

This table presents the raw data, already anonymized to protect the identity of the source farms. The information pertains to dairy farms and includes the number of lactating cows, milk production, and water consumption. The table also displays efficiency indices such as L water cow⁻¹ day⁻¹ and L water kg milk⁻¹ day⁻¹. Data are categorized by three production systems (confined, semi-confined, and pasture-based) and different water uses, including drinking water and water used for cleaning. Additionally, the table includes the efficiency score derived from the DEA method, specifically the BCC model.本表格展示了已完成匿名化处理的原始数据，以保护来源奶牛场的身份隐私。本次数据涉及奶牛场，涵盖泌乳母牛存栏量、牛奶产量及耗水量三类核心信息。表格同时列示了两项用水效率指标：单位泌乳母牛每日耗水量（L water cow⁻¹ day⁻¹）与单位牛奶产量每日耗水量（L water kg milk⁻¹ day⁻¹）。数据按照三种生产模式（圈养、半圈养及放牧型）以及不同用水场景进行分类，用水场景包括饮用水与清洁用水。此外，本表格还包含通过数据包络分析（Data Envelopment Analysis, DEA）的BCC模型计算得到的效率得分。
