Nutritive and mineral content of hay from three species-rich floodplain meadows, England, 2020-21

Dataset includes concentration of crude protein, fibre (ADF and NDF), metabolisable energy (ME) and a range of dietary minerals from three species-rich floodplain meadows in Central England. Samples were taken between May and September in 2020 and 2021. Graminoid:forb ratio, Accumulated Growing Degree-days (thermal time), Accumulated Actual Evapotranspiration and yield are recorded for each date. The data were originally collected to investigate the seasonal dynamics of yield, dietary minerals, protein and energy in floodplain meadow hay.

本数据集收录了英格兰中部三个物种丰富的河漫滩草地的粗蛋白浓度、纤维（ADF和NDF）、可代谢能量（ME）以及一系列膳食矿物质。样品采集于2020年5月至2021年9月之间。记录了每个日期的禾本科植物与杂类草的比例、累积生长度日（热时间）、累积实际蒸散量以及产量。数据最初收集的目的是为了研究河漫滩草地干草中产量、膳食矿物质、蛋白质和能量的季节性动态。详细的研究方法请参阅：https://doi.org/10.21954/ou.ro.00097871。关于此数据集的详细信息，请查阅：https://doi.org/10.5285/361f0587-4cc6-48df-9f7e-8ade331cf8d5。
