Description: This study was designed to find out the relationship between the blood concentrations of some macro-minerals particularly magnesium, calcium and inorganic phosphate in camels with fractured jaw compared to their concentrations in healthy camels. Twenty camels with jaw fractures were included in this study; another twenty nine apparently healthy camels served as control group. The affected camels were subjected to a detailed physical examination. They showed obvious clinical signs of mandibular fracture. In some cases bilateral fracture was observed, the fractured part of the mandible being dropped ventrally from a site just cranial to the first premolar. Also, there was a wound in the buccal cavity exposing the fractured bone ends, dribbling of saliva from mouth commissure associated with partial or complete loss of appetite. Blood samples were obtained from the affected and healthy camels. The obtained results revealed that the mean values of these macro-minerals concentrations in the blood were significantly lower in camels with jaw fracture (2.85+-0.29 mmol/l, 0.92+-0.17 mmol/l and 0.13+-.07 mmol/l for calcium, magnesium and inorganic phosphate respectively) compared to respective values in healthy camels
