Resumo: This research aimed to compare carcasses of purebred and crossbred Nellore females reared uniquely on pasture (Brachiaria decumbens and Brachiaria brizantha cv. Marandu). Breeds assessed consisted of purebred Nellore (16) and Nellore x Santa Gertrudis crossbred (16), being 32 ± 1.5 months old. All animals were slaughtered as they reached 450 kg. Crossbred females showed higher slaughter, hot and cold carcass weights and longer lengths (P < 0.05). Conversely, purebred animals attained greater carcass yields (P < 0.05). Nonetheless, crossbred females had higher primal cut weights and plate/ flank percentage (P < 0.05). Also, non-carcass components as kidneys, liver, kidney-pelvic-heart fat showed higher weights for crossbred females (P < 0.05). Thus, regarding beef cattle reared and finished exclusively on grazing areas, crossbred females (Nellore x Santa Gertrudis) may be the most profitable ones for cattle raisers, since they produce heavier slaughtering carcasses. Notwithstanding, they might be interesting for meat industry, for yielding more in prime cuts than purebreds, even if raised at the same conditions and slaughtered at same age.

Marandu). Foram utilizadas 16 da raça Nelore e 16 Nelore x Santa Gertrudis, com idade média de 32 ± 1,5 meses. As fêmeas foram pesadas mensalmente sem jejum e quando o peso corporal médio das  Nelore atingiu 450 kg, todas foram submetidas a jejum de sólidos e água por 16 horas e pesadas. Os animais foram abatidos no mesmo dia quando as fêmeas Nelore atingiram o peso aproximado de 450 kg. As fêmeas cruzadas apresentaram maiores (P<0,05) peso de abate, de carcaça quente e resfriada e comprimento da carcaça, já as Nelore apresentaram o melhor rendimento de carcaça (P<0,05). Os pesos de todos os cortes primários, o rendimento da ponta de agulha e os pesos dos rins, fígado, gordura perirenal-pélvica-inguinal foram maiores (P<0,05) para as fêmeas cruzadas. Quando se produz animais exclusivamente em pastagem, o uso de fêmeas Nelore x Santa Gertrudis é a melhor opção para a obtenção de carcaças mais pesadas. Por outro lado, o melhor rendimento de cortes comercias é obtido com a exploração de fêmeas Nelore, criadas nas mesmas condições.UEL2016-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2377210.5433/1679-0359.2016v37n6p4213Semina: Ciências Agrárias; Vol. 37 No. 6 (2016); 4213-4220Semina: Ciências Agrárias; v. 37 n. 6 (2016); 4213-42201679-03591676-546Xreponame:Semina.
