Thirteen female camels were used in this study to investigate the changes in some haematological parameters during the different stages of lactation including early lactation, mid-lactation and the last stage of lactation. A significant decrease (P<0.001) in mid and late lactation, compared to early lactation was recorded for the following parameters: number of white blood cells, number of lymphocytes, number of monocytes, number of granulocytes, per cent ratio of lymphocytes and mean corpuscular volume. While, the levels of per cent ratio of monocytes, per cent ratio of granulocytes, red blood cells and haematocrit were low in early lactation then showed a significant raise in mid and late lactation (P<0.001). Moreover, The levels of mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration were high during early lactation, then significantly decreased (P 0.05). The current study gives baseline data about the value change of the main haematological parameters during lactation in female camels in the Algerian desert and these results could be used as a database for the diagnosis of different disorders and also for upcoming research in camels.

This study aims to investigate the changes of biochemical blood parameters in female dromedary camels during lactogenesis and galactopoiesis in Algeria. Therefore, 56 serum samples were collected from females (monthly) for last four months antepartum (AP) and the first four months postpartum (PP) and biochemical profiles were investigated. The data were statistically analyzed using General Linear Model with repeated measures and Benferroni test as post-hoc test. Glucose increased significantly at the third month PP, with sudden decrease after that. Triglycerides peaked significantly in second month PP compared to fourth month PP and first month AP. Cholesterol elevated significantly at the third month PP comparatively to the first months AP and PP. Low-density lipoprotein increased significantly substantially from the second to the fourth month PP. High-density lipoprotein lowered significantly in the first month AP to rise substantially at third month PP. Calcium increased considerably from second to third months PP. A significant difference of iron was marked between the third month AP and the fourth month PP. Urea dropped abruptly at first month PP and elevated considerably in the second month PP. Creatinine marked a substantial rise from third to first month AP to decrease afterward. It increased significantly at third months PP compared to antepartum period. ALT indices of second month AP decreased notably in the second month PP. These findings indicate that lactogenesis and galactopoiesis period have substantial impacts on metabolites, proteins, hepatic enzymes, and minerals in the blood of female camels.

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.
