Resumo: | The study aimed at evaluating an alternative supplementation system, designed to significantly anticipate the 48-60-month average slaughter age observed in steers, in the Northeast semi-arid region. The liveweight gain of 45 weaned male calves was monitored under three treatment groups: (C) exclusive and yearlong grazing on caatinga; (CB) rainy season grazing on caatinga and dry season grazing on buffelgrass (Cenchrus ciliaris, L.) pasture; (CBL) the same as CB plus leucaena (Leucaena leucocephala (Lam.) de Wit.) hay supplementation, during the dry season. Observations were made over two dry and two rainy periods, a 711-day total period. At the end of the experimental period, the leucaena-supplemented animals were, on average, 33.4 kg and 107.5 kg heavier (P < 0.05) than those of the CB and C groups, respectively. Results showed that it was possible, for steers, even with an inadequate leucaena hay supply, to achieve the regional average slaughter weight with, at least, 14 months of anticipation. |

Para isto, avaliou-se o ganho de peso de 45 bezerros anelorados, desmamados, distribuídos em três grupos: (C) pastejo exclusivo em caatinga durante todo o ano; (CB) pastejo em caatinga, no período verde, e em capim-buffel (Cenchrus ciliaris, L.) no período seco; (CBL) o mesmo que CB mais suplementação com feno de leucena (Leucaena leucocephala (Lam.) de Wit.), no período seco. As observações foram feitas durante dois períodos secos e dois chuvosos, num total de 711 dias. Ao final do período experimental, os animais do grupo suplementado com leucena estavam, em média, 33,4 kg e 107,5 kg mais pesados (P < 0.05) que os dos grupos CB e C, respectivamente. Os resultados indicam que mesmo com uma oferta quantitativamente inadequada de leucena foi possível a obtenção de animais com o mesmo peso médio ao abate observado na região, com, pelo menos, 14 meses de antecipação.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGuimarães Filho, ClovisSoares, José Givaldo Góes1997-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4723Pesquisa Agropecuaria Brasileira; v.32, n.8, ago. 1997; 861-864Pesquisa Agropecuária Brasileira; v.32, n.8, ago. 1997; 861-8641678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4723/7322info:eu-repo/semantics/openAccess2015-03-12T18:27:50Zoai:ojs.seer.sct.embrapa.br:article/4723Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-12T18:27:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
