This study was carried out to evaluate fi nal weight, carcass characteristics, chemical composition and fatty acid profi le in Longissimus muscle (LM) of young bulls of the crossbred type: Canchim×Aberdeen Angus (n=7), Nellore×Aberdeen Angus (n=12) and Nellore×Continental breeds (Simmental, Limousin) (n=8), fi nished in feedlot. Canchim×Aberdeen Angus and Nellore×Aberdeen Angus bulls had similar fi nal body and hot carcass weights, while these were lower for the Nellore×Continental breed crosses. Fat thickness and LM area were inferior in the Nellore×Continental breed group. In contrast, lipid contents were larger in the LM of the Canchim×Aberdeen Angus bulls. Nellore×Aberdeen Angus and Nellore×Continental breed crosses featured a similar percentage of polyunsaturated, n-6 and n-3 fatty acids, and a larger ratio of polyunsaturated and saturated and n-6 and n-3 fatty acids in comparison to Canchim×Aberdeen Angus bulls.
