ABSTRACT
This study was performed in order to investigate the haematological and biochemical profiles in the growing dromedary camel calves during the first month of age. For this reason, twelve term camel calves were enrolled. Five blood samples were collected from each calf; within 12h of birth and at 1, 2, 3 and 4 wk of age. A complete blood count was carried out. Serum samples were used to determine the concentrations of total protein, albumin, globulin, calcium, phosphorus and magnesium. The serum activity of aspartate aminotransferase (AST), γ-glutamyl transferase (GGT) and alkaline phosphatase (ALP) were also measured. Leukocyte count was higher at birth, then decreased at wk 1-2 after birth then increased at wk 2-4. On the contrary, lymphocyte count was low at birth and then increased during the whole experimental period. Red blood cells showed high levels during the first 12h after birth, a significant decrease at wk 3 and wk 4 of life. Similar results were recorded for haemoglobin and haematocrit values. The total protein concentrations did not differ significantly among all the tested time-points. The albumin concentration was lowest at birth then increased significantly at all other points. Globulin concentration was highest at parturition then decreased significantly at all other tested points. The AST activity was lowest at parturition then increased significantly at all other points. On the contrary, the GGT and ALP serum activity was highest at parturition then decreased significantly at all other points. Calcium concentrations did not differ significantly among all the tested points. Phosphorus concentration was lowest at birth then increased significantly from this point onward. Magnesium concentration was lowest at birth and at 1 wk of age, and then increased significantly other points. Data in this study can be used as a reference for dromedary camel calves during the first month of age for a more precise interpretation of haematology and biochemical tests.
