Resumo: The objective of the experiment was to study the body factors related to the variation of dressing percentage in castrated males or non-pregnant females, slaughtered at fourteen months of age. The animals were finished with energetic supplementation on cultivated pasture. Twelve contemporary animals of each sex were used, all crossbred Nellore (3/8) x Hereford (5/8) from the same herd. Farm live weight, slaughterhouse live weight and hot carcass weight were superior in males, being 365.8; 350.4 and 203.4 kg, respectively, while the females showed 310.3; 294.5; and 168.6 kg, in the same order. Males also showed higher hot carcass dressing percentage in relation to farm live weight (55.6 vs 54.4%) and in relation to slaughterhouse weight (58.1 vs 57.2%) than females. The lower female dressing percentage was a result of the higher hide (9.03 vs 7.96%), inguinal fat in the udder of heifers or cod fat of steers (1.02 vs .67%), full digestive tract (19.35 vs 16.84%), empty rumen plus reticulum (2.34 vs 1.91%) and empty intestine (2.54 vs 2.11%) percentages. There was no significant difference between sexes in heart, liver, lungs, kidneys and spleen percentages, being, respectively, 0.40, 0.93, 1.01, 0.22 and 0.35% in males and 0.41, 0.98, 1.02, 0.22 and 0.30% in females, cited in the same order.KEY WORDS: braford, hide, organs, rumen, sex.

Os animais foram terminados com suplementação energética sobre pastagem cultivada. Utilizaram-se doze animais de cada sexo, mestiços Nelore (3/8) x Hereford (5/8), contemporâneos do mesmo rebanho. Os pesos de fazenda, de frigorífico e de carcaça quente foram superiores nos machos, sendo de 365,8; 350,4 e 203,4 kg, respectivamente, enquanto as fêmeas apresentaram 310,3; 294,5; e 168,6 kg, citados na mesma ordem. Bovinos machos também apresentaram maiores rendimentos de carcaça quente em relação ao peso de fazenda (55,6 vs 54,4%) e em relação ao peso de frigorífico (58,1 vs 57,2%) do que as fêmeas. O menor rendimento de carcaça das fêmeas deveu-se ao maior percentual de couro (9,03 vs 7,96%), gordura inguinal, junto ao úbere das fêmeas ou à capadura dos machos (1,02 vs 0,67%), trato digestivo cheio (19,35% vs 16,84%), rúmen mais retículo vazios (2,34 vs 1,91%) e intestino vazio (2,54% vs 2,11%). Não houve diferença significativa entre sexos nos percentuais de coração, fígado, pulmões, rins e baço, sendo, respectivamente, 0,40%, 0,93%, 1,01%, 0,22% e 0,35% nos machos e 0,41%, 0,98%, 1,02%, 0,22% e 0,30% nas fêmeas, citados na mesma ordem.PALAVRAS-CHAVES: Braford, couro, órgãos, rúmen, sexo.Universidade Federal de Goiás2010-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/674710.5216/cab.v11i1.6747Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 11 No. 1 (2010); 53 - 61Ciência Animal Brasileira / Brazilian Animal Science; v. 11 n. 1 (2010); 53 - 611809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/6747/6508https://revistas.ufg.br/vet/article/view/6747/7610Vaz, Fabiano NunesRestle, JoãoArboitte, Miguelangelo ZieglerPascoal, Leonir LuizFaturi, CristianJoner, Guilhermeinfo:eu-repo/semantics/openAccess2010-04-06T13:47:46Zoai:ojs.revistas.ufg.br:article/6747Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:25.564346Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
