ABSTRACT Twelve yearling bulls were assigned to one of three groups: (1) control with no treatment; (2) implanted with hormones; or (3) fed with the β‐agonist clenbuterol. Groups b and c were also fed with dexamethasone during the finishing period. After slaughter, six muscles aged for 1, 3, 7, 14 and 21 days at 4C were used for the analyses of the meat quality. Clenbuterol‐fed animals presented the highest muscle percentage (74.72%) and diameter B of the loin (8.05 cm), whereas hormone‐implanted animals had the highest bone percentage (16.12%) and lower percentage of muscle (68.15%). Meat from animals fed with clenbuterol tended to have higher water‐holding capacity than from the other groups. Clenbuterol‐fed animals also presented the lowest CIE a * (redness) values. Instrumental texture was affected by the growth promoters used, although it varied with muscle or aging time. The use of clenbuterol brought about tougher meat, but the combination with dexamethasone might decrease toughness.
