Resumo: | The purpose of this trial was to evaluate the liveweight gain of steers receiving or not zeranol and grazing three guinea grass pasture: grass alone, grass with nitrogen fertilization, and grass/legume (Panicum maximum/Neonotonia wightii). Guzerá steers with 220 kg of mean liveweight were used. Stocking rates were adjusted according to the put-and-take system. Animals were weighed and the pastures were sampled at 35-day intervals. Daily weight gains were similar in all pastures, whereas gain/hectare increased for guinea grass with nitrogen. Daily weight gain and gain/hectare were 557 g and 394 kg for implanted animals and 466 g and 324 kg for not implanted animals, therefore, animals implanted gained more 1953% for daily weight gain and 21.60% for gain/hectare in all pastures. |

Foram usados novilhos da raça Guzerã com peso vivo médio de 220 kg. O sistema de pastejo foi rotativo, sendo o ajuste pasto-animal realizado pelo método de carga variável. As pesagens dos animais foram realizadas a cada 35 dias. Os resultados revelaram ganhos diários de peso vivo semelhantes nos três tipos de pastagens, apesar de o ganho por hectare ter sido superior na pastagem adubada com N. Os animais que receberam implante de zeranol revelaram ganhos de 557 g/dia, e 394 kg/ha e os não implantados, 466 g/dia e 324 kg/ha, acarretando, portanto, superioridade nos respectivos ganhos a favor dos primeiros de 19,53% e 21,60%, respectivamentePesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFavoretto, VanildoVieira, Paulo de FigueiredoSampaio, Alexandre Amstalden MoraesOliveira, Mauro Dal Secco deMalheiros, Euclides Braga2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13427Pesquisa Agropecuaria Brasileira; v.25, n.3, mar. 1990; 427-434Pesquisa Agropecuária Brasileira; v.25, n.3, mar. 1990; 427-4341678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13427/7561info:eu-repo/semantics/openAccess2014-04-17T14:30:41Zoai:ojs.seer.sct.embrapa.br:article/13427Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:30:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
