Abstract
Thirty Charolais bulls, divided into 3 groups, received in their finishing period (180d) either 0 (C) or 500 (T1) or 1000 (T2) mg/head/d of vitamin E (a-tocopherol acetate). At 72h after slaughter (680 kg l.w.) a sample of l.thoracis muscle from each carcass was collected and determinations of lipid content and fatty acid composition of lipid fractions were carried out. Intramuscular fats (1.75%) contained 50.4, 37.6 and 12.0% of saturated, mono-and poly-unsaturated fatty acids respectively. Dietary vitamin E level did not affect in a substantial way fatty acid composition of lipid fractions.
