Chemical Composition and Proteomics of Camel Milk at Different Lactation Stages

In this study, the basic nutritional components and physicochemical indicators of camel milk were measured during the early, middle, late, and dry lactation stages to explore their variation patterns throughout the entire lactation process. Meanwhile, quantitative proteomics was employed to analyze the differential proteins between camel colostrum and mature milk and their potential functional information was uncovered. The results showed that the contents of basic nutrients (protein, fat, lactose, and total solids) in camel milk was the highest at the early lactation stage, and subsequently decreased as lactation proceeded. The physicochemical properties of camel milk varied with lactation period. Milk density and refractive index were the highest at the early lactation stage, and then significantly decreased (P © 2024 Chinese Chamber of Commerce. All rights reserved.
