Resumo: | The performance and characteristics of 18 carcasses of feedlot-finished Zebu cattle were evaluated over 93 days in confinement or semi-confinement systems. In the semi-confinement system, two strategies of pasture deferral were adopted, 40 days (40DD) and 80 days (80DD). The feed of animals in confinement was composed of 24% of grass silage Urochloa spp. and 76% concentrate, on dry matter, freely supplied twice daily. Grazing animals received 4 kg of animal concentrate per day. The final fasting weight of the animals in confinement (534.92 kg) was higher than that of animals semi-confined in 40DD (475.33 kg) and 80DD (460.67 kg) pastures, because of the higher daily weight gain (1.37 vs. 0.82 and 0.64 kg, respectively). Feedlot-finished animals had a greater carcass gain (0.91 kg animal-1 day-1), resulting in a higher carcass weight (296.47 kg), higher thickness of external fat (5.42 mm), weight and percentage of side cut (17.88 kg and 12.20%), and weight and percentage of fat in the carcass (74.50 kg and 25.22%). However, no difference was observed for the metric and developmental characteristics of the carcass, which allowed good quality carcasses to be obtained, independent of the strategies evaluated. Feedlot-finished Zebu cattle provide heavier and bulky carcasses, leading to higher revenue per marketed carcass. |

No semiconfinamento foram adotadas duas estratégias de diferimento da pastagem, com 40 dias (40DD) e 80 dias (80DD). A ração dos animais confinados foi composta de 24% de silagem de capim Urochloa spp. e 76% de concentrado, na matéria seca, fornecida à vontade duas vezes ao dia, enquanto que os animais em pastejo receberam 4 kg de concentrado animal-1 dia-1. O peso final em jejum dos animais confinados (534,92 kg) foi superior aos semiconfinados em pastagem 40DD (475,33 kg) e 80DD (460,67 kg), devido ao maior ganho de peso diário (1,37 vs. 0,82 e 0,64 kg, respectivamente). Animais terminados em confinamento tiveram maior ganho de carcaça (0,91 kg animal-1 dia-1), determinando maior peso de carcaça quente (296,47 kg), com melhor acabamento de gordura (5,42 mm), peso e porcentagem do costilhar (17,88 kg e 12,20%) e peso e porcentagem de gordura na carcaça (74,50 kg e 25,22%). Contudo, não se observou diferença para as características métricas e de desenvolvimento da carcaça, possibilitando obter carcaças com boa qualidade independente das estratégias avaliadas. A terminação de bovinos anelorados em confinamento proporciona carcaças mais pesadas e com melhor acabamento, permitindo maior receita por carcaça comercializada.UEL2018-08-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTerminação de bovinosTerminação de bovinosapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3040610.5433/1679-0359.2018v39n4p1725Semina: Ciências Agrárias; Vol. 39 No. 4 (2018); 1725-1736Semina: Ciências Agrárias; v. 39 n. 4 (2018); 1725-17361679-03591676-546Xreponame:Semina.

However, no difference was observed for the metric and developmental characteristics of the carcass, which allowed good quality carcasses to be obtained, independent of the strategies evaluated. Feedlot-finished Zebu cattle provide heavier and bulky carcasses, leading to higher revenue per marketed carcass. |
