​​Factors Affecting Serum Trace Elements of Breeding Ewes in Central Saudi Arabia

D.R. Derar, A. Ali, T.I. Almundarij, E.M. Abdel-Elmoniem, T.M. Alhassun
Background: Trace elements are indispensible for animal production and reproduction. Their requirements rely on many factors. Some of these factors have been studied in earlier reports but still other factors under investigation. The aim of the present study was to investigate factors affecting the level of manganese (Mn), selenium (Se), iron (Fe) and zinc (Zn) of sheep in Qassim Region, Central Saudi Arabia. 
Methods: Total of 131 clinically healthy and non-pregnant ewes were assigned for this study. Ewes were classified according to breed, parity, body condition score, housing system and feeding type. The animals were bled immediately after examination and sera were analyzed for trace elements using spectrometry. 
Result: Results showed that Awassi breed had higher Se, Fe and Zn levels than other breeds. Parity affected Se and Fe levels. Age, body condition score and parity affected Zn concentration. It can be concluded that breed, parity, age, body condition score, housing and feeding type could affect the level of serum trace elements in breeding ewes in central Saudi Arabia.
