| Popis: | The objective of this work was to evaluate cattle from different genetic groups finished in a feedlot and subject to the climatic conditions of the Upper Pantanal region of Mato Grosso do Sul, Brazil, according to the behavior, carcass performance and characteristics, and quality of fresh or aged meat. Eight animals from each genetic group were confined for 84 days, including: Nelore (NEL), Aberdeen Angus x Nelore (AAN) and Canchim x Nelore (CAN). The animals were slaughtered using the cerebral concussion technique and cutting of the jugular vein, followed by removal of the hide and evisceration. The data was analyzed in a completely randomized design using PROC GLM, with the means compared by the Tukey test at 5% significance. For the behavioral parameters there was no effect of breed (P > 0.05). There was a negative correlation (P 0.05). The tenderness parameters (shear force and myofibrillar fragmentation index) were lower and higher (P |
