Abstract: This work was carried-out to study the chemical composition and fatty acids profile among chuck, rump, striploin, topside and knuckle from crossbred (½ Nellore x ½ Charolais) heifers finished in feedlot. The knuckle, striploin and topside showed higher (P < 0.05) moisture (75.19, 73.87 e 74.36%) and ash contents (1.09; 1.08 and 1.13%) than the chuck (71.18 e 0.93%) and rump (71.58 e 1.07%), respectively. On the other hand, lipid contents of chuck (7.40%) and rump (5.19%) were higher (P < 0.05) than striploin (2.42%), topside (1.76%) and knuckle (1.69%). The chuck cholesterol content (57.63mg/100 g of muscle) was higher (P < 0.05) than striploin (49.71mg/100 g of muscle) and topside (46.55mg/100 g of muscle). The knuckle percentages of C 18:3 n-3 (0.98%), C20:4n-6 (1.88%), C 20:5 n-3 (0.74%), AGPI (9.34%), n-6 (7.61%) and n-3 (1.73%) were higher (P
