The aim of this study was to evaluate the influence of age and sex on the concentration of total serum protein measured by the biuret method and protein fractions determined using cellulose acetate electrophoresis in apparently healthy camels (Camelus dromedarius). Blood samples were collected from 21 camels (12 males and 9 females). The camels were further divided into two groups: 12 young camels at the age of 3 months to 2 years and 9 adult camels at the age of 3-15 years. Cellulose acetate electrophoresis of serum proteins identified five protein fractions in adult camels as young camels, these five protein fractions include albumin, α1 and α2, β and γ-globulins. In adult camels, serum levels (g/l) of total protein, albumin, α1-globulins, α2-globulins, β-globulins and γ-globulins were 80.9±3.10, 42.9±3.10, 1.3±0.22, 2.2±0.30, 11.8±0.30 and 22.6±0.20, respectively. However, in young camels, these levels (g/l) were 66.8±2.90, 40.2±2.40, 1.0±0.14, 2.6±0.30, 10.6±0.80 and 12.3±1.20, respectively. The albumin/globulin (A/G) ratio was 2.08±0.28 in adult camels and 3.77±0.53 in young ones. The mean serum concentrations of total protein and γ-globulins were significantly (P<0.05) higher and the A/G ratio was significantly lower in adult camels compared to young camels. The mean concentrations of γ-globulins were significantly higher and the A/G ratio was significantly (P<0.05) lower in females compared to male camels. The results of the present study indicate a significant effect of age and sex on the concentrations of some of the serum protein fractions in dromedary camels.
