Abstract

We examined the liver mineral concentrations of semi-wild cattle breeds (Highland, Galloway, Rode Geus) grazing in natural or near-natural flood-prone areas in the Netherlands. These breeds are employed as part of trophic rewilding initiatives aimed at maintaining biodiverse ecosystems through natural grazing patterns. Our primary goal was to derive RIs for liver mineral concentrations for these cattle populations. We collected and analyzed liver samples from 96 cattle from 14 sites in the Netherlands and used inductively coupled plasma mass spectrometry to measure concentrations of trace elements and heavy metals, including arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, vanadium, and zinc. The statistical analysis included Pearson product moment correlations and k-means clustering to evaluate patterns within the data. The highest significant correlations were between liver cadmium concentrations and animal age, and between liver copper and selenium concentrations. Breed-related differences were found for liver cadmium and molybdenum concentrations, but we could not isolate breed-differences in forage selection from environmental variables such as soil composition. Liver copper levels in many animals were below thresholds typically used to indicate copper deficiency in farmed cattle.

荷兰荒野地区牛肝脏中微量矿物质和重金属的参考区间。
我们检查了在荷兰自然或接近自然的洪水易发地区放牧的半野生牛品种(高地,加洛韦,罗德Geus)的肝脏矿物质浓度。这些品种被用作营养野化倡议的一部分,旨在通过自然放牧模式维持生物多样性生态系统。我们的主要目标是得出这些牛群的肝脏矿物质浓度的RIs。我们从荷兰的14个地点收集并分析了96头牛的肝脏样本,并使用电感耦合等离子体质谱法测量微量元素和重金属的浓度,包括砷、镉、铬、钴、铜、铁、铅、锰、钼、镍、硒、钒和锌。统计分析包括Pearson积差相关性和k-means聚类来评估数据中的模式。肝镉浓度与动物年龄、肝铜浓度与硒浓度呈极显著相关。肝脏镉和钼含量存在品种相关差异,但不能将饲料选择的品种差异与土壤组成等环境变量分离。许多动物的肝铜水平低于通常用于指示养殖牛缺铜的阈值。
