One hundred eighty female Arabian camels aged 3−16 years were used to determine the reference intervals for selected blood parameters during different physiological states. Venous blood was collected for determining erythrocyte and leukocyte parameters, blood glucose, protein fractions, Ca++, Mg++ and Pi. The reference ranges for TEC, PCV, Hb, MCV, MCH, MCHC, TLC, neutrophils, eosinophils, basophils, lymphocytes and monocytes were 4.06−5.03×106/μL, 4.8−11.2 g/dL, 24.8−30.6%, 29.7−39.4 fl, 25.2−44.4 pg, 19.6−39.8 g/dL, 11−13×103/μL, 41−49%, 5−6%, 1−3%, 45−50% and 1−2%, respectively and for blood glucose, TP, albumin, α1, α2, β1, β2 and γ-globulins, A/G ratio, Ca++, Mg++ and Pi were 67−100 mg/dL, 29−72 g/L, 46−78%, 1−7%, 2−10%, 5−14%, 3−14%, 10−27%, 1−15 and 5−9, 1−2, 4−6 mmol/L, respectively. The values of Hb were lower in the growing and early lactating camels than in dry ones, whereas TEC, monocytes percentage and serum Ca++, Mg++, Pi were higher (P<0.05). The TEC, TP and albumin were higher in late pregnant camels than in dry and early lactating ones (P<0.05). The α1, α2 and β1 were lower in late pregnant camels than in dry females, whereas they showed higher values in early lactating ones (P<0.05). Neutrophil and lymphocyte percentages showed higher and lower values (P<0.05) in late pregnant and early lactating camels than in dry females, respectively. The blood parameters of female camels varied significantly depending on their physiological state. The findings are most likely applied to evaluate physiological and metabolic adaptations to growth, pregnancy and lactation.
