Resumo: The objective of this study was to evaluate the animal performance, carcass characteristics and meat quality of F1 Angus-Nellore steers and heifers, feedlot finished with high degree of subcutaneous fat deposition. The experimental design was completely randomized, with two treatments (steers and heifers) and 11 replicates (animals). Twenty-two bovines with initial age of 18 months of age, 11 steers and 11 heifers, with initial body weight of, respectively, 354.86±43,66 and 353.82±39,80 kg were used. The animals were finished in confinement (114 days) with a diet containing 200 g kg-1 of corn silage and 800 g kg-1 of concentrate composed mainly of corn grain and soybean meal. The dry matter intake (9.42 vs. 9.24 kg day-1), mean daily weight gain (1.44 vs. 1.38 kg day-1), feed conversion (6.49 vs. 7.05 kg of dry matter kg-1 of weight gain), hot carcass weight (284.62 vs. 268.16 kg) and the subcutaneous fat thickness (12.09 vs. 13.05 mm) were similar between steers and heifers (respectively). The hot carcass yield was higher (P < 0.05) for steers (58.14 vs. 55.53%). The steers presented a higher proportion of the forequarter (39.26 vs. 37.53%), while heifers had a higher proportion of pistol cut (49.87 vs. 48.85%). The meat of steers showed darker color (P < 0.05). The shear force of the meat and marbling score did not differ between sexual conditions, with mean values of 5.43 kgf cm-2 and 10.14 points (median), respectively. Except for the proportion of primary cuts, carcass yield and meat color, F1 Angus-Nellore heifers present similar animal performance, carcass and meat characteristics in relation to steers, feedlot finished with high degree of subcutaneous fat deposition.

O delineamento experimental foi o inteiramente casualizado, com dois tratamentos (novilhos e novilhas) e 11 repetições (animais). Foram utilizados 22 bovinos com 18 meses de idade inicial, 11 novilhos e 11 novilhas, com peso corporal inicial de 354,86±43,66 e 353,82±39,80 kg, respectivamente. Os animais foram terminados em confinamento (114 dias) com dieta contendo 200 g kg-1 de silagem de milho e 800 g kg-1 de concentrado composto principalmente por grão de milho moído e farelo de soja. O consumo de matéria seca (9,42 vs. 9,24 kg dia-1), o ganho de peso médio diário (1,44 vs. 1,38 kg dia-1), a conversão alimentar (6,49 vs. 7,05 kg de matéria seca kg-1 de ganho de peso), o peso de carcaça quente (284,62 vs. 268,16 kg) e a espessura de gordura subcutânea (12,09 vs. 13,05 mm) foram similares entre novilhos e novilhas (respectivamente). O rendimento de carcaça quente foi maior (P < 0,05) nos novilhos (58,14 vs. 55,53%). Os novilhos apresentaram maior proporção de dianteiro (39,26 vs. 37,53%), enquanto as novilhas apresentaram maior proporção do traseiro especial (49,87 vs. 48,85%). A carne dos novilhos apresentou coloração mais escura (P < 0,05). A força de cisalhamento da carne e o marmoreio não diferiram entre as condições sexuais, com valores médios de, 5,43 kgf cm-2 e 10,14 pontos (mediano), respectivamente. Exceto em relação à proporção dos cortes primários, rendimento de carcaça e cor da carne, novilhas jovens F1 Angus-Nelore apresentam similar desempenho animal, características de carcaça e de carne em relação aos novilhos abatidos com similar grau de acabamento.UEL2019-06-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3448410.5433/1679-0359.2019v40n4p1681Semina: Ciências Agrárias; Vol. 40 No. 4 (2019); 1681-1694Semina: Ciências Agrárias; v. 40 n. 4 (2019); 1681-16941679-03591676-546Xreponame:Semina.
