Abstract

Some trace elements are essential for the health of vertebrates, but little is known about their function, the amounts required, and the factors influencing their metabolism in tortoises. The aim of this study was therefore to measure trace elements (chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn)) in heparinized blood plasma of Hermann’s tortoises (Testudo hermanni) (n = 520) from March to September 2022 using inductively coupled plasma mass spectrometry (ICP-MS) and to establish specific reference intervals. Additionally, the influence of sex, season, and region of sample collection on the measured values were evaluated. Significant (p ≤ 0.05) sex-specific differences were found for Cu, Mg, and Mn; seasonal differences were found for Cr, Cu, Mn, Mo, and Se; and the region in which the tortoises were kept significantly impacted Cr, Cu, Fe, Mg, Mo, and Se levels. The results show that all of these factors should be consider when establishing and interpreting blood trace element levels in tortoises.

中欧赫尔曼陆龟（Testudo hermanni）体内按性别、季节和采样区域划分的微量元素含量

一些微量元素对脊椎动物的健康至关重要，但人们对它们的功能、所需数量以及影响陆龟新陈代谢的因素知之甚少。因此，本研究的目的是测量陆龟血浆中的微量元素（铬（Cr）、钴（Co）、铜（Cu）、铁（Fe）、镁（Mg）、锰（Mn）、钼（Mo）、硒（Se）和锌（Zn））、利用电感耦合等离子体质谱法（ICP-MS）对 2022 年 3 月至 9 月期间赫尔曼陆龟（Testudo hermanni）（n = 520）肝素化血浆中的锌（Zn）含量进行分析，并确定具体的参考区间。此外，还评估了性别、季节和样本采集地区对测量值的影响。结果发现，铜、镁和锰的性别差异显著（p ≤ 0.05）；铬、铜、锰、钼和硒的季节差异显著；龟的饲养地区对铬、铜、铁、镁、钼和硒的含量有显著影响。结果表明，在确定和解释陆龟血液中的微量元素水平时，应考虑所有这些因素。

期刊介绍： Animals (ISSN 2076-2615) is an international and interdisciplinary scholarly open access journal. It publishes original research articles, reviews, communications, and short notes that are relevant to any field of study that involves animals, including zoology, ethnozoology, animal science, animal ethics and animal welfare. However, preference will be given to those articles that provide an understanding of animals within a larger context (i.e., the animals'' interactions with the outside world, including humans). There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental details and/or method of study, must be provided for research articles. Articles submitted that involve subjecting animals to unnecessary pain or suffering will not be accepted, and all articles must be submitted with the necessary ethical approval (please refer to the Ethical Guidelines for more information).
