Supplementary α-tocopherol acetate in full-fat rapeseed-based diets for pigs: effect on performance, plasma enzymes and meat drip loss

Twenty‐four Large White × Landrace pigs were individually fed, from 50 to 90 kg live weight, either a control (CONT) diet containing palm oil or one of three diets based on full‐fat rapeseed (250 g kg−1) (diets RD). The RD diets were supplemented with 0, 200 or 500 mg DL‐α‐tocopherol acetate (ATA) kg−1 diet (diets RD0, RD200 and RD500 respectively). Diets were formulated to be isonitrogenous and isocaloric. Daily live weight gain was significantly increased (p
