Understanding the physicochemical characteristics of cisternal, alveolar, and residual milk is essential for optimizing milking management, improving milk quality evaluation, and monitoring udder health in agricultural animals. This knowledge contributes to more efficient milk production and better utilization of dairy resources. In Kazakhstan, the use of machine milking for camels is still insufficiently developed. Therefore, studying the physicochemical characteristics of these types of milk of dromedary Camels has great importance for improving milking practices, evaluating milk quality, and ensuring better utilization of camel dairy resources. The present study investigated the composition of cisternal (C), alveolar (A) and residual (R) milk of one humped n -14 camels (Camelus dromedarius) in 150±15 days after calving from South Kazakhstan. The camels were injected with Atosiban (CAS 90779-69-4) at a dose of 10 μg/kg of body weight and 4 ml of oxytocin (RK-LS-5№022381) per animal, after which the camels were milked by hand. The data on individual milk yield were recorded immediately after milking, then which milk samples were then collected and analyzed for composition in containers with cooling agents. Cisternal, alveolar and residual milk volumes and compositions as protein, dry matter, solid non-fat, fat, density and pH, somatic cells were evaluated within 1-3 hours after milking. On average, the proportion of cisternal milk was 2.77%, alveolar was 91.18% and residual milk 6.05% of total milk yield in dromedary Camels. The fat contents (%) of C, A and R for dromedary camels were 1,94; 4,15 and 5,96 respectively while the pH was between 6.1 and 6.2 for all types of milk. The protein (%) of C, A, R in dromedary camels was 3,15; 3,11 and 3,05 respectively.
