Camel milk is highly valued for its nutritional and therapeutic properties. However, extensive management systems often lead to inconsistent milk quality. This study aimed to evaluate the effects of sodium diacetate (SDA) and Aspergillus oryzae (AO) as dietary additives on the milk composition and fecal microbiota of lactating Bactrian camels. Thirty camels of similar parity were randomly assigned to three groups: a control group (TMR), an SDA group (1000 mg/kg DM), and an AO group (40 g/d). The trial lasted 45 days, including a 15-day acclimation period. Routine milk components were analyzed every 10 days, while fatty acids and fecal microbiota were assessed on day 30. Results showed that SDA supplementation significantly increased the concentrations of Vitamin E, Vitamin C, and unsaturated fatty acids (UFA) in milk without affecting milk yield or routine components. Microbiota analysis indicated that SDA treatment significantly increased the abundance of the fungal genus Melanocarpus, although no broad shifts in microbial community structure were observed across groups. In conclusion, dietary SDA (1000 mg/kg) effectively enhances bioactive substances in camel milk while maintaining stable milk quality. These findings suggest that SDA is a viable “green” additive for improving the functional value of camel milk in intensive production systems.
