Abstract | Minerals are essential for the health and productivity of livestock. The present study was conducted to determine the serum concentrations of lead (Pb), cadmium (Cd), copper (Cu), zinc (Zn), iron (Fe), and selenium (Se) of Barki sheep reared in El-Hammam city, Egypt. Clinically healthy Barki sheep (n=40, 2-4 years) were randomly selected in equal numbers from two different farms. Another twenty healthy Barki sheep (2-4 years) were obtained from another farm as control. Animals from three different farms were classified according to water source: Borg El Arab as control (Tap water); El-Hammam I (Surface water); El Hammam II (groundwater). Water and serum samples were prepared for the detection and estimation of selected minerals using Flame Atomic Absorption Spectrometer. Serum BUN and creatinine concentration were also assessed as renal function parameters. The results revealed an alteration in metals concentration in water samples from one site to another. A higher Pb and Se levels were El Hammam II (GW, 1.21ppm) followed by El Hammam I (SW, 0.88ppm) and control (TW, 0.83 ppm).The levels of Cu, Zn, and Fe were below EWQS limits, while Cd was not detected in all samples. For serum metal analysis, variable concentrations were detected in examined sheep of different groups. Serum concentration for Fe and Se were significantly higher (P<0.001), while it was reduced considerably (P<0.001) for Cu and Zn. However, the serum levels of heavy metals, including Pb and Cd, were low to be detected. The results of BUN were significantly elevated (P<0.001) in examined sheep of El-Hammam city than the control, while no significant changes in creatinine levels (P>0.05) were observed between groups. It is concluded that groundwater quality needs improvement and continuous monitoring for water quality. The animal needs to be fed with oral supplementation of required minerals, and further studies in subject matter are necessary to ascertain study outcome and its practical applications further.
