In order to determine feeding differences on natural antioxidant vitamin delivery, two contrasting diets: lucerne (ALF) and sorghum silage (SS) were analysed. Diets showed different profiles for fat-soluble vitamins. ALF was higher in a-tocopherol, b-carotene, and retinol than SS diet. On the contrary, SS diet was higher in ã- and ä- tocopherol due to the soy expeller contribution in these isomers. ALF diet favoured higher milk production and protein yield in comparison to SS, whereas fat content was the opposite (p
