饲料植物很有价值，因为它们可以维持野生和驯化的食草动物，并维持肉类、牛奶和其他商品的运输。饲料植物含有不同数量的纤维、木质素、矿物质和蛋白质，并且可以被食草动物消化的组织比例也不同。这些营养成分是消费者增长率、繁殖成功率和行为的重要决定因素。编制数据集以量化植物物种内和植物物种间饲料植物营养价值的变化，并评估植物功能群和生物气候区之间的变化。从已发表的文章中获得了 1255 份地理定位记录，其中包含 30 个国家种植的 136 种饲料植物物种的 3774 项营养价值测量值。饲料营养价值的空间变异表明气候改变了植物的营养价值。生长在干旱和赤道地区的饲料植物通常比生长在温带和苔原地区的饲料植物含有更少的可消化物质；含有较多的纤维和木质素，而较少的蛋白质。这些模式可能揭示了为什么草食动物的体型、消化和迁徙策略在温暖和干燥地区有所不同。该数据集还揭示了饲料植物提供的营养的变化能力，这可能会推动消费物种共存。不同物种的可消化植物组织比例为 2% 至 91%。植物材料中纤维含量为 23-90%，蛋白质为 2-36%，木质素为 1-21%，矿物质为 2-22%。平均而言，草和树叶含有最多的纤维，而草本豆科植物含有最多的蛋白质，树叶含有最多的木质素。然而，每个功能组内都有个别物种营养丰富。该数据集可用于识别具有有用营养特征的饲料植物物种或来自不同功能组的物种混合物，这些植物可用于培养以提高牲畜生产力并为野生食草动物保护策略提供信息。本文的在线版本 (10.1007/s10265-018-1024-y) 包含补充材料，可供授权用户使用。
Forage plants are valuable because they maintain wild and domesticated herbivores, and sustain the delivery of meat, milk and other commodities. Forage plants contain different quantities of fibre, lignin, minerals and protein, and vary in the proportion of their tissue that can be digested by herbivores. These nutritive components are important determinants of consumer growth rates, reproductive success and behaviour. A dataset was compiled to quantify variation in forage plant nutritive values within- and between-plant species, and to assess variation between plant functional groups and bioclimatic zones. 1255 geo-located records containing 3774 measurements of nutritive values for 136 forage plant species grown in 30 countries were obtained from published articles. Spatial variability in forage nutritive values indicated that climate modified plant nutritive values. Forage plants grown in arid and equatorial regions generally contained less digestible material than those grown in temperate and tundra regions; containing more fibre and lignin, and less protein. These patterns may reveal why herbivore body sizes, digestion and migration strategies are different in warmer and drier regions. This dataset also revealed the capacity for variation in the nutrition provided by forage plants, which may drive consumer species coexistence. The proportion of the plant tissue that was digestible ranged between species from 2 to 91%. The amount of fibre contained within plant material ranged by 23–90%, protein by 2–36%, lignin by 1–21% and minerals by 2–22%. On average, grasses and tree foliage contained the most fibre, whilst herbaceous legumes contained the most protein and tree foliage contained the most lignin. However, there were individual species within each functional group that were highly nutritious. This dataset may be used to identify forage plant species or mixtures of species from different functional groups with useful nutritional traits which can be cultivated to enhance livestock productivity and inform wild herbivore conservation strategies.
