Resumo: The study was designed to evaluate a physical model performance of a cow-calf operation system for the semi-arid region, in Brazil. Native pastures (caatinga) were grazed during the rainy season and buffel grass pastures over the rest of the year. Leucaena supplementation, under rotational grazing and as hay, was provided during the dry season. Performance parameters, monitored from November 1991 to October 1995, showed a 72.8% annual calving rate and a very low mortality rate. Weaning weights of calves averaged 153.4 kg at 205 days. Production of calf weaned was 109.5 kg/cow run/year and 25.5 kg/ha/year. Performance data can be concluded to be very promising if considered that above half the total area was covered by native pastures and that leucaena hay supplementation was strongly limited by occurrence of a severe drought period.

A caatinga foi pastejada no período verde, e o capim buffel no restante do ano. A suplementação com leucena ocorreu no período seco, sob pastejo direto e feno no cocho. Parâmetros de desempenho, monitorados de novembro de 1991 a outubro de 1995, mostraram uma taxa média de parição da ordem de 72,8% ao ano e taxas de mortalidade praticamente nulas. O peso vivo médio dos bezerros aos 205 dias de idade foi de 153,4 kg e a produção de bezerros desmamados foi de 109,5 kg/matriz exposta/ano e de 25,5 kg/hectare/ano. Os resultados são considerados bastante expressivos, considerando-se que mais da metade da área era ocupada com pastagens nativas de caatinga e que a oferta de leucena foi limitada pela ocorrência de uma forte estiagem.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGuimarães Filho, ClovisSoares, José Givaldo Góes1999-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5421Pesquisa Agropecuaria Brasileira; v.34, n.9, set. 1999; 1721-1727Pesquisa Agropecuária Brasileira; v.34, n.9, set. 1999; 1721-17271678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5421/2613info:eu-repo/semantics/openAccess2012-02-16T11:53:17Zoai:ojs.seer.sct.embrapa.br:article/5421Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-02-16T11:53:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
