Influence of season and pasture feeding on the content of α-tocopherol and β-carotene in milk from Holstein, Brown Swiss and Modicana cows in Sicily

The objective of this study was, therefore, to evaluate α-tocopherol and β-carotene concentrations in cows’ milk by monitoring two grazing seasons in Sicily (spring and fall) as well as the summer no-pasture season. Besides diet, other factors such as animal breed, stage of lactation and health status may influence fat-soluble antioxidant vitamin concentration in milk
