Dataset used in the research article "Methane emissions of dairy cows in two pasture-based systems with contrasting intensification strategies in Uruguay: operational simplicity vs maximised productivity".

Updated version of the dataset used in the article “Methane emissions in pasture-based dairy systems with contrasting intensification strategies in Uruguay in two periods: operational simplicity vs maximised productivity”, published in Animal – Open Space journal. The file contains two sheets: Metadata_paper ANOPES-D25-00065: Includes individual cow records for all measurements across two periods and the two pasture-based dairy systems (operational simplicity – OS – and high productivity – HP). Each row represents one cow on one sampling date and contains information on methane emissions, milk production traits, and animal characteristics. Variables description: Provides detailed definitions and units (or types) for all variables included in the dataset.本数据集为发表于《Animal – Open Space》期刊的论文《乌拉圭两阶段内不同集约化策略牧场乳业系统的甲烷排放：操作简易性 vs 产能最大化》中所使用数据集的更新版本。 该文件包含两个工作表： 1. 论文元数据 ANOPES-D25-00065：涵盖两个阶段与两种牧场型乳业系统（操作简易型（OS）与高产型（HP））下所有测量项的单头奶牛记录。每一行对应单次采样日期下的一头奶牛，包含甲烷排放、产奶性状以及动物个体特征相关信息。 2. 变量说明：对数据集内所有变量提供详细定义与单位（或数据类型）说明。
