The present study investigated the effects of different reproductive stages on haematological parameters of mature local dairy female dromedary camels (n=52) in El Oued region in southeastern Algeria under a semi-intensive breeding system. The haematological parameters analysed included white blood cell count (WBC), lymphocyte count (LYM), lymphocyte percentage (LYM%), monocyte count (MON), monocyte percentage (MON%), granulocyte count (GRAN), granulocyte percentage (GRAN%), red blood cell count (RBC), haemoglobin (HGB), haematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), and platelet count (PLT). The study focused on four distinct stages: dry period, early pregnancy, lactogenesis, and galactopoiesis. Significant increases (P<0.001) were observed in MON% and GRAN% during the dry period and early pregnancy. MCV values were significantly higher (P<0.05) during the dry period than early pregnancy. However, GRAN during these stages was significantly lower (P<0.001) than during galactopoiesis. Lactogenesis and galactopoiesis stages were characterised by significant elevations (P<0.001) in WBC, LYM, and LYM%. Additionally, HGB, MCHC, and MCH values were significantly higher (P<0.001) during these stages. Conversely, RBC, HCT, and PLT were significantly lower (P<0.001) during lactogenesis and galactopoiesis. Interestingly, the MON during galactopoiesis was significantly lower (P<0.001) than during the dry period. These findings demonstrate that haematological parameters in female dromedary camels undergo significant alterations across different reproductive stages. This knowledge can contribute to improved reproductive management strategies and provide insights into the physiological adaptations of camels during various reproductive phases in semi-intensive breeding systems.
