Little is known about the serum levels of trace elements in donkeys and horses in Saudi Arabia. This study aimed to investigate the levels of some trace elements in these two species in the eastern region of Saudi Arabia and to compare the obtained results with the reference values.
Seventeen Arabian horses and twenty eight Hassawi donkeys were randomly selected for this study. All of the studied healthy animals were kept under a uniform feeding protocol without any minerals supplementations. Atomic absorption spectrometer is used to estimate the serum concentrations of selenium (Se), manganese (Mn), chromium (Cr), copper (Cu), iron (Fe), and zinc (Zn) in the analyzed samples.
Significant differences between horses and donkeys were observed in three of the studied elements (Se, Mn, and Cr). Statistically significant differences were found in serum Se and Cr between male and female horses. The male donkey showed higher Mn, Cu, and Zn levels than female animals.
The obtained results of trace element levels in serum of Hassawi donkeys and Arabian horses in Saudi Arabia are considered as the first values to be published for these breeds. When compared to other animals, the measured amounts of Se, Mn, Cr, Cu, Fe, and Zn in the serum of horses and donkey are often differed, possibly because of the varying living or feeding conditions. Moreover, there were some differences in some of the trace elements concentrations related to animal's gender and species (horses and donkeys), which will be considered in the interpretation of the laboratory data.
沙特阿拉伯驴和马的血清微量元素水平鲜为人知。本研究旨在调查沙特阿拉伯东部地区这两个物种的某些微量元素水平，并将所得结果与参考值进行比较。
本研究随机选取了17匹阿拉伯马和28头哈萨维驴。所有研究的健康动物均按照统一的饲养方案饲养，不添加任何矿物质。使用原子吸收光谱仪估算分析样本中硒（Se）、锰（Mn）、铬（Cr）、铜（Cu）、铁（Fe）和锌（Zn）的血清浓度。
在所研究的三种元素（Se、Mn和Cr）中，马和驴之间存在显著差异。雄性和雌性马的血清Se和Cr存在统计学显著差异。雄性驴的Mn、Cu和Zn水平高于雌性动物。
沙特阿拉伯哈萨维驴和阿拉伯马血清中微量元素水平的所得结果被视为这些品种首次公布的值。与其他动物相比，马和驴血清中Se、Mn、Cr、Cu、Fe和Zn的测量量通常不同，这可能是由于生活或饲养条件不同所致。此外，某些微量元素浓度在动物性别和物种（马和驴）方面存在一些差异，这在实验室数据解释中将会予以考虑。
