T; total mixed ration comprised of the same concentrate, maize
silage and wheat straw: TMR) and breed (Limousine: LI; Retinta: RE) on growth performance, carcass characteristics
and meat quality. The diets were administrated ad libitum for 193 days. The average dailyweight gainwas
similar (P N 0.05) for both diets, while the LI bulls grew significantly (P b 0.05) more than RE. T bulls showed
higher L*, a* and rib bone percentage. TMR bulls showed higher carcass yield, conformation and fatness, and
greater changes in ultrasound measurements, except Δ UGMDand rib fat percentage. Instrumental meat quality,
except shear force at 1 and 21 days of ageing, was not affected (P N 0.05) by the diets. Breed significantly affected
most of the analyzed characteristics.
