Extract

Dairy products composition and quality are strongly influenced by the nature of the diet fed to cows, including their composition in micronutrients, among them carotenoids. These compounds are pigments that develop provitamin A and antioxidant functions, take part in the maintenance of cell communication, enhance the immune function, and UV skin and macula protection (Van den Berg et al., 2000). In dairy products, besides to having nutritional and sensorial properties, they have been recognized as tracer compounds indicating animal feeding management (review of Nozière et al., 2006). Factors controlling their concentration in cow’s milk must therefore be highlighted. The aim of this study was to determine the variation in plasma and milk carotenoids concentrations when cows shifted from a low-carotenoid diet to diets containing various levels of carotenoids.
