To assess this study, weaned piglets (at 28 days) received three dietary treatments until 39 days of age: (1) 12,5 mg alpha tocopheryl acetate/kg feed (2) 6,75 mg/l d-alpha tocopherol in drinking water (ratio 1:2) (3) 4,5 mg/l d-alpha tocopherol in drinking water (ratio 1:3). Alpha- Tocoferol accumulation was not significantly affected in any of the tissues analysed which would indicate a more efficient absorption of natural vitamin E in drinking water than the synthetic source in feed. Moreover, the lowest supplementation in drinking water (group 1:3) led to similar concentrations of vitamin E in tissues than the group supplemented with higher concentration (group 1:2). Consequently, when weaned piglets are fed under the minimum established requirements the minimum natural vitamin E supplementation to produce an equivalent tissues vitamin E concentration would be establish at 1:3 (water:feed).
