Effect of the dietary supplement on the chemical composition of milk

Under the arid climatic conditions of Kazakhstan, the improvement of camel milk productivity is closely linked to the quality and balance of feeds. In a previously published study (Processes, 2025, 13(10), 3362), a technology for extruded compound feed supplemented with wormwood (Artemisia) as a biologically active additive was developed. In the present study, the effect of different doses of wormwood (0, 10, and 15%) in the compound feed on the milk productivity and chemical composition of camel milk was evaluated. Feeding was carried out for 10 days at the “Shyngys” farm (Saryagash city). Monitoring included measurements of daily milk yield, fat content, protein content, and total solids. It was found that increasing the wormwood content to 15% in the extruded compound feed contributed to a 1.0 L increase in milk yield (from 1.9 to 2.9 L), an increase in fat by 0.62%, protein by 0.56%, and total solids by 1.8%. Feed analysis revealed the highest levels of flavonoids and vitamins A, B1, and B3 in the 15% wormwood sample. Regression analysis confirmed the statistical significance of the effects of the additive and feeding duration (R² = 0.92–0.97; p < 0.001). Response surface analysis showed a positive interaction of factors. The optimal formulation was identified as extruded compound feed containing 15% wormwood, which ensures improved milk productivity and milk quality of camels.
