Resumo: First calving interval and, age and weight at second calving of 57 Canchim and 57 Nellore cows, raised on pasture in the state of São Paulo, Brazil, were studied. The analyses of variance indicated no effects of calf sex on calving intervals and age at second calving. Season of the previous calving had no effect on calving interval, but significantly affected (P < 0.01) age at second calving, as a consequence of age at first calving. Cows that calved during the rainy-season (November to April) showed lower age at second calving. The breed x season of calving interaction affected significantly (P < 0.05) weight at second calving, and the Canchim cows were heavier than the Nellore ones. There was no difference between the calving intervals of me Canchini (441 days) and Nellore (418 days) cows. The age at second calving was lower (P < 0.10) for Canchim (1,620 days) than for Nellore (1,668 days) cows, as a consequence of the lower age at first calving of the Canchim females.

As vacas foram criadas em regime exclusivo de pasto no estado de São Paulo. As análises de variância indicaram que não houve efeito significativo de sexo do bezerro sobre o intervalo entre partos, nem sobre a idade ao segundo parto. A época do parto anterior não influenciou o intervalo entre partos, mas apresentou efeito significativo (P < 0,01) sobre a idade ao segundo parto, como uma consequência da idade no primeiro parto. As vacas que pariram na época das águas (novembro a abril) apresentaram menor idade ao segundo parto. A interação raça x época do parto influenciou significativamente (P < 0.05) o peso ao segundo parto, sendo que as vacas Canchim foram mais pesadas do que as vacas Nelore. Não houve diferença estatística entre os intervalos entre partos das raças Canchim (441 dias) e Nelore (418 dias). A idade ao segundo pano foi menor (P < 0,10) na raça Canchim (1.620 dias) do que na raça Nelore (1.668 dias), como consequência da menor idade ao primeiro parto dos animais da raça Canchim.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlencar, Maurício Mello deBugner, Manfred2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16452Pesquisa Agropecuaria Brasileira; v.24, n.10, out. 1989; 1217-1220Pesquisa Agropecuária Brasileira; v.24, n.10, out. 1989; 1217-12201678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16452/10718info:eu-repo/semantics/openAccess2014-08-29T16:53:38Zoai:ojs.seer.sct.embrapa.br:article/16452Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-29T16:53:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
