ABSTRACT
Aim: 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.
Materials and Methods: 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.
Results: 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.
Conclusion: 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.
Keywords: donkey, horse, serum, trace elements.
