Resumo: | The objective of this work was to establish the influence of breeding ram and feeding on performance of lambs in confinement. The experimental design was completely randomized, in a 2x4 factorial arrangement. The treatments were two genetic groups (Santa Inês x not defined breed (NDB) and Somalis x NDB) and concentrate (corn, soybean meal plus mineral salt) at 15%, 30%, 45% and 60%. Thirty two animals were confined in individual stalls and each was one repetition. The diets were composed by concentrate and roughage, leucaena hay (Leucaena leucocephala), as a complete ration. The slaughter weight increased and the feed efficiency improved (P < 0.05) as concentrate in diet was increased. A quadratic effect on dry matter intake and organic matter intake with maximum values of 35.29% and 35.36%, respectively, was observed. All estimated gross margin were positive. There was no difference (P > 0.05) among concentrates; however, the genetic group Somalis x NDB was superior (P < 0.05) to Santa Inês x NDB. |

O delineamento experimental foi o inteiramente casualizado, com arranjo fatorial 2x4, costituído de dois grupos genéticos (Santa Inês x sem raça definida (SRD) e Somalis x SRD) e concentrado de milho em gão, farelo de soja e sal mineral a 15%, 30%, 45% e 60%. Trinta e dois animais foram confinados em baias individuais e cada um constituiu uma repetição. As dietas eram compostas de feno de leucena (Leucaena leucocephala) e concentrado, na forma de ração completa. O aumento de concentrado na dieta dos animais causou incrementos lineares (P < 0,05) no peso de abate e melhoria na conversão alimentar. Houve efeito quadrático no consumo de matéria seca e de matéria orgânica, com máximos estimados em 35,29% e 35,36% de concentrado, respectivamente. Todas as margens brutas de lucro estimadas foram positivas. Não houve diferença (P > 0,05) entre os concentrados, porém o grupo genético Somalis x SRD mostrou-se superior (P < 0,05) ao Santa Inês x SRD.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBarros, Nelson NogueiraVasconcelos, Vânia Rodrigues deAraújo, Marcelo Renato Alves deMartins, Espedito Cezário2003-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6679Pesquisa Agropecuaria Brasileira; v.38, n.9, set. 2003; 1111-1116Pesquisa Agropecuária Brasileira; v.38, n.9, set. 2003; 1111-11161678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6679/3736info:eu-repo/semantics/openAccess2014-08-11T19:31:32Zoai:ojs.seer.sct.embrapa.br:article/6679Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:31:32Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
