Resumo: | The objective of this work was to evaluate the performance of crossbred steers post-weaned in an integrated crop-livestock system (ICL) and finished in a feedlot, fed either a high-level concentrate diet or whole corn with no roughage. Weaned calves of two breed groups – ½ Angus × ½ Nellore, and ½ Charolais × ¼ Angus × ¼ Nellore – were allotted in a completely randomized experimental design (CRD). During the rainy season, the ½ Angus × ½ Nellore animals showed a higher performance than the ½ Charolais × ¼ Angus ×¼ Nellore ones, with 0.748 and 0.490 kg average daily gain, respectively. The productivity in the post-weaning period was 926 kg ha-1 body weight in a 11-month period, in the ICL system. Subsequently, the animals were confined and fed high-concentrate diet or whole corn with no roughage, in a CRD with a 2×2 factorial arrangement. In the feedlot, the ½ Charolais × ¼ Angus × ¼ Nellore animals showed lower values for carcass average daily gain, carcass yield, and slaughter weight than the ½ Angus × ½ Nellore animals. The high productivity in the ICL shows that this strategy, associated with the use of crossbreeding during the post-weaning and finishing stages, can be indicated for the new demand for a sustainable livestock activity. |

Bezerros desmamados de dois tipos de cruzamento – ½ Angus × ½ Nelore e ½ Charolês × ¼ Angus × ¼ Nelore – foram distribuídos em delineamento experimental inteiramente casualizado (DIC). No período das águas, os animais ½ Angus × ½ Nelore apresentaram desempenho superior ao dos animais ½ Charolês × ¼ Angus × ¼ Nelore, com ganho médio diário de 0,748 e 0,490 kg, respectivamente. A produtividade na recria foi de 926 kg ha-1de peso corporal no período de 11 meses, no sistema de ILP. Posteriormente, os animais foram confinados e alimentados com dietas com alto nível de concentrado ou exclusivamente de concentrado, em DIC, com arranjo fatorial 2×2. No confinamento, os animais ½ Charolês × ¼ Angus × ¼ Nelore apresentaram valores menores de ganho médio diário de carcaça, rendimento de carcaça e peso ao abate do que os animais ½ Angus × ½ Nelore. A elevada produtividade no sistema ILP mostra que essa estratégia, associada ao uso de cruzamentos durante a recria e a terminação, pode ser indicada para a nova demanda por uma pecuária sustentável.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Matsuda Indústria e Comércio Ltda.Vaccinar Nutrição e Saúde animalCosta, Patrícia MonteiroBarbosa, Fabiano AlvimAlvarenga, Ramon CostaGuimarães, Sérgio TeixeiraLampeão, Ângelo AndréWinkelströter, Larissa KretliMaciel, Isabella Cristina de Faria2017-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/23401Pesquisa Agropecuaria Brasileira; v.52, n.5, maio 2017; 355-365Pesquisa Agropecuária Brasileira; v.52, n.5, maio 2017; 355-3651678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/23401/13765https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23401/15359https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23401/17667Direitos autorais 2017 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2017-06-22T19:48:26Zoai:ojs.seer.sct.embrapa.br:article/23401Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2017-06-22T19:48:26Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
