ABSTRACT
This study was carried out to evaluate final weight, carcass characteristics, chemical composition and
fatty acid profile 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), finished in feedlot. Canchim×Aberdeen Angus and Nellore×Aberdeen Angus bulls had
similar final 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.
