Resumo: | The objective was to evaluate the development of external body components and the distribution of internal fat of Charolais (CH) and Nellore (NE) steers, fed with different concentrate level in the diet. The steers were distributed in six treatments constituted by three concentrate level: 35, 50 or 65% (dry matter basis) and two genetic group (Charolais or Nellore). NE steers fed with 65% concentrate in diet showed higher EBW yield, it was not different to CH and NE steers fed with 50% concentrate. Head weigth in relation to EBW was decrease with the increase of the proportions concentrate (4.67, 4.30 and 4.28 to 35; 50 and 65% concentrate, respectively). The head weigh also was lower from NE steers in relation to CH steers (4.30 versus 4.54, respectively). The absolute total weight of internal fat was higher (P<.05) for steers fed with high concentrate proportions (18.13; 22.58 and 21.74 kg to 35, 50 and 65% concentrate) and to CH steers in relation to NE (22.52 versus 19.11, respectively). CH steers showed highest internal fat. Similarly, steers fed high-concentrate ratio had also higher deposit of internal fat. |

Avaliaram-se os componentes externos e a distribuição da gordura interna de novilhos das raças Charolês (CH) ou Nelore (NE), alimentados com diferentes proporções de concentrado na dieta. Os novilhos foram distribuídos em seis tratamentos que corresponderam a três níveis de concentrado: 35, 50 e 65% (com base na matéria seca) e dois grupos genéticos (Charolês e Nelore). Os novilhos NE alimentados com 65% de concentrado na dieta apresentaram maior rendimento de corpo vazio (RCV), não diferindo dos novilhos CH e NE alimentados com 50% de concentrado. O peso da cabeça ajustado para peso de corpo vazio (PCV) foi menor para os animais que consumiram dieta com proporção mais alta de concentrado (4,67, 4,30 e 4,28 para 35, 50 e 65% de concentrado, respectivamente) e para os novilhos da raça NE em relação aos CH (4,30 contra 4,54, respectivamente). O peso absoluto total das gorduras internas foi superior (P<0,05) para os novilhos alimentados com proporções mais elevadas de concentrado (18,13; 22,58 e 21,74 kg para 35 50 e 65% de concentrado), e para os novilhos CH em relação aos NE (22,52 contra 19,11, respectivamente). Novilhos CH apresentam maior deposição de gordura interna do que novilhos NE. Novilhos alimentados com proporções mais altas de concentrado apresentam maiores deposições de gordura interna.UEL2013-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1084410.5433/1679-0359.2013v34n2p863Semina: Ciências Agrárias; Vol. 34 No. 2 (2013); 863-874Semina: Ciências Agrárias; v. 34 n. 2 (2013); 863-8741679-03591676-546Xreponame:Semina.
