Se utilizaron 39 animales de un grupo genético (5/8 Holstein x 3/8 Cebú), sacrificados en tres grupos, de 13 animales cada uno, a diferentes edades (25, 29 y 33 meses, respectivamente), según las normas técnicas del Centro Cárnico del Instituto de Ciencia Animal de la República de Cuba. Se evaluó la calidad de la carne de machos enteros en finalización en un sistema silvopastoril con Leucaena leucocephala, complementados con harina de maíz. The youngest animals showed lower values of tenderness and greater luminosity with respect to the older groups. Tenderness values differed (p <0.01) among all groups slaughtered at 25, 29 and 33 months (7.47, 8.82 and 9.75 kg, respectively). A difference (p <0.01) was observed in the luminosity indicator (L*) between the youngest age group compared to the oldest. The pH was also determined in two carcass muscles ( Semimembranosus and Longissimus dorsi). The criterion of 60 randomly selected consumers was analyzed for the evaluation. Analysis of variance was performed to evaluate instrumental (color, temperature, pH, texture) and sensory indicators in meat samples taken from the Longissimus dorsi muscle between the tenth and thirteenth rib. Thirty-nine animals of the same genetic group (5/8 Holstein x 3/8 Zebu) were used, sacrificed in three groups, of 13 animals each, at different ages (25, 29 and 33 months, respectively), according to the technical standards of the Meat Center of the Institute of Animal Science of the Republic of Cuba. Meat quality of non-castrated males in finishing stage was evaluated in a silvopastoral system with Leucaena leucocephala, supplemented with corn meal.
