Online published on 23 December, 2019. Abstract This study was aimed to compare between lead blood levels and its hazardous effects on hematological and biochemical parameters in Awassi sheep grazed on pastures located in Najaf center and sheep grazed in desert of Al-Najaf province-Iraq. The results showed that the lower blood lead levels in sheep grazed on desert with values enclosed in generally within the normal limits, while, higher blood lead levels were shown in sheep grazed on pasture located in the city center of Al-Najaf, with average values significantly higher than the maximum limits. On the other hand, there are a significant decrease (p<0.05) in hematological parameters (Red blood cells (RBCs), hemoglobin (Hb), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC), also, a significant increase (p<0.05) in biochemical parameters (alanine aminotransferase (ALT), aspartate aminotransferase (AST), sorbitol dehydrogenase (SDH), blood urea nitrogen (BUN) and creatinine) but decrease in total protein (TP) in sheep grazed on pasture located in the city center compared with sheep grazing in desert Al-Najaf. Thus, the current study showed that elevated mean blood lead level above the acceptable limit of (0.1 ppm) in all Sheep living in the city Centre, suggesting that iron deficiency anemia may amplify the effect of lead contamination in the environment.
