Summary: The objective of this work was to evaluate carcass characteristics and testicular biometry of non-castrated Hereford (H), 3/4H 1/4 Nellore (N), 5/8H 3/8N and 3/4 Charolais (C) 1/4 N males, slaughtered at fourteen months of age. No statistical difference occurred among genetic groups for final and carcasses weights and dressing percentages. The sawcut yield was higher in 3/4CN than other genotypes. Ribcut yield was higher for 5/8HN in relation to 3/4HN and 3/4CN. Longissimus dorsi area was higher for 3/4CN (71.5 cm2) animals in relation to Hereford (63.5 cm2). Hereford animals also showed lower leg length than all other groups. The 3/4CN males showed lower (2.6 mm) subcutaneous fat thickness than Hereford (5.0 mm), 5/8HN (4.1 mm) and 3/4HN (4.1 mm) ones. In conclusion, all genetic groups get compatible carcass characteristics for young cattle market. Besides,  muscular development related characteristics, such as conformation and sawcut yield, were better in Charolais crossbred genotype, while characteristics related to fat deposition, such as fat thickness and ribcut yield, were better in Hereford and crossbred Hereford genotypes.KEYWORDS: crossbred; feedlot; Hereford; Nellore; yield.

Não houve diferenças estatísticas entre os grupos genéticos para pesos de fazenda, de carcaça e rendimentos de carcaça. A percentagem de serrote foi maior nos animais 3/4CN em relação aos outros genótipos. A percentagem de ponta de agulha foi maior nos 5/8HN em relação aos 3/4HN e 3/4CN. A área de Longissimus dorsi foi maior nos animais 3/4CN (71,5 cm2) em relação aos Hereford (63,5 cm2). Animais Hereford também apresentaram menor comprimento de membro posterior do que todos os demais grupos. Os machos 3/4CN apresentaram menor (2,6 mm) espessura de gordura subcutânea do que os Hereford (5,0 mm), 5/8HN (4,1 mm) e 3/4HN (4,1 mm). Concluiu-se que as características relacionadas à musculosidade, como a conformação e o rendimento de serrote foram melhores no genótipo mestiço Charolês, enquanto as características relacionadas à deposição de gordura, como espessura de gordura e rendimento de ponta de agulha, foram melhores nos animais Hereford e mestiços.PALAVRAS-CHAVE: confinamento; cruzamento; Hereford; Nelore; rendimentos.Universidade Federal de Goiás2012-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/1751110.5216/cab.v13i3.17511Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 13 No. 3 (2012); 306-314Ciência Animal Brasileira / Brazilian Animal Science; v. 13 n. 3 (2012); 306-3141809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/17511/11955https://revistas.ufg.br/vet/article/view/17511/11956https://revistas.ufg.br/vet/article/view/17511/15427Vaz, Fabiano NunesFlores, Jorge Luis C.Vaz, Ricardo ZambardaPascoal, Leonir Luizde Ávila, Mozer M.info:eu-repo/semantics/openAccess2012-09-29T02:15:59Zoai:ojs.revistas.ufg.br:article/17511Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2012-09-29T02:15:59Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)false
