Resumo: | This study aimed to assess the carcass and meat characteristics of European crossbred young bulls or Zebu crossbred young bulls feedlot finished with diets with high percentage of concentrate (80%) containing different levels of grounded millet grain as replacement for grounded corn grain (0, 33, 66 and 100%). Forty-five young bulls with genotype predominance of Aberdeen Angus and forty-four young bulls with genotype predominance Nellore with average initial weight of 317.8 and 320.7 kg, respectively, and average age of 21 month, were allocated in 16 collective pens. At the end of the finishing period were slaughtered six animals of each genetic group, chosen according to the body weight and degree of finishing each treatment. The experimental design was the completely randomized design with treatments in a 4x2 factorial arrangement using six replicates. The replacement of corn grain by millet grain did not significantly influence slaughter weight (480.4 kg), hot carcass weight (259.5 kg), carcass yield (54.1%) and subcutaneous fat thickness (3.95 mm). Young bulls with genotype predominance of Aberdeen Angus showed significantly higher values for slaughter weight (507.6 vs. 453.3 kg), hot carcass weight (269.6 vs. 249.3 kg) and longissimus dorsi area (65.34 vs 56.83 cm2), however, were lower in carcass yield (53.2 vs. 55.00%). Millet grain can be used in substitution to corn grain for finishing steers since it does not change carcass traits of economic interest. |

Foram confinados, em 16 baias coletivas, 45 tourinhos com predominância genética Aberdeen Angus e 44 tourinhos com predominância genética Nelore, com peso médio inicial de 317,8 e 320,7 kg, respectivamente, e 21 meses de idade. Ao final do período de confinamento foram abatidos seis animais de cada grupo genético, escolhidos de acordo com o peso corporal e o grau de acabamento médio de cada tratamento. O delineamento experimental foi inteiramente casualizado, com os tratamentos em arranjo fatorial 4x2, com seis repetições. A substituição do grão de milho pelo grão de milheto não influenciou significativamente o peso ao abate (480,4 kg), peso de carcaça quente (259,5 kg), rendimento de carcaça quente (54,1 %) e espessura de gordura subcutânea (3,95 mm). Tourinhos com predominância genotípica Aberdeen Angus apresentaram valores significativamente superiores para peso ao abate (507,6 vs 453,3 kg), peso de carcaça quente (269,6 vs 249,3 kg) e área do músculo longissimus dorsi (65,34 vs 56,83 cm2), porém, foram inferiores quanto ao rendimento de carcaça quente (53,2 vs 55,0 %). O grão de milheto pode ser utilizado em substituição ao grão de milho, pois não altera as principais características de carcaça de interesse econômico de novilhos terminados em confinamento.UEL2015-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1538110.5433/1679-0359.2015v36n2p943Semina: Ciências Agrárias; Vol. 36 No. 2 (2015); 943-960Semina: Ciências Agrárias; v. 36 n. 2 (2015); 943-9601679-03591676-546Xreponame:Semina.
