Descripción
The objective of this work was to evaluate the fatty acid (FA) profile of Longissimus thoracis (LT) muscle from cattle finished in feedlot, fed with grains and silage produced in an integrated crop-livestock system (ICL). Nellore (IBW = 344.4 ± 30 kg, n = 25) and Angus x Nellore (IBW = 426.5 ± 27 kg, n = 25) crossbred young bulls were used, and the diet had a concentrate: roughage ratio of 65:35. The crossbred animals had higher levels of saturated FA (SFA) (P = 0.05) and lower levels of unsaturated FA (UFA) (P = 0.02) and monounsaturated FA (MUFA) (P = 0.04). There was no significant difference for the concentrations of PUFA, ?-6, ?-3, and PUFA/SFA and ?-6/?-3 ratio between the breed compositions (P > 0.05). Nellore produced meat with a better fatty acid profile due to the physiological maturity stage at which this group was slaughtered. The production of quality meat through ICL resources is an interesting strategy for adding value to the system.
