Resumo: The aim of this study was to estimate genetic parameters, including genetic and phenotypic correlations as well as heritabilities, for production and reproduction traits of buffaloes in the Brazilian Amazon. Heritability estimates varied from 0.04 to 0.05 for FCI (first calving interval), 0.0 to 0.26 for CI (calving interval) and 0.0 to 0.25 for SP (service period), reflecting high environmental variation for these traits. For AFC (age at first calving) the heritabilities varied from 0.12 to 0.38. The Murrah breed showed the highest heritabilitiy for BW (birth weight) (0.62). Genetic correlations varied between 1.00 and -1.00 depending on the traits. There were negative genetic correlations between AFC and MFW (mature female weight) (-0.12 to -1.00 depending on breed) as well as between SP, BW and MFW (0.01 to -1.00). Permanent environment effects of the traits were low (0.000 to 0.155) and only that for CI in the Jafarabadi breed could be considered significant (0.458). Maternal effects for birth weight were low to medium (0.11, 0.17, 0.37 and 0.04 for Carabao, Jaffarabadi, Mediterranean and Murrah, respectively).

As estimativas de herdabilidade (h2) das características variaram de 0,04 a 0,05 no primeiro intervalo entre partos, de 0,0 a 0,26 no intervalo entre partos, e de 0,0 a 0,25 no período de serviço, refletindo grande influência ambiental. Na idade ao primeiro parto, a herdabilidade variou de 0,12 a 0,38. Em relação ao peso ao nascer, a raça Murrah foi a que apresentou a mais alta h2 (0,62). As correlações genéticas variaram de 1,00 a -1,00. Foram negativas as correlações genéticas entre idade ao primeiro parto e peso da fêmea adulta (-0,12 a -1,00 dependendo da raça), assim como as correlações entre período de serviço, peso ao nascer e peso da fêmea adulta (0,01 a -1,00). O efeito de ambiente permanente (c2) variou de 0,000 a 0,155. Somente no intervalo entre partos para a raça Jafarabadi pode-se considerar que houve c2 significativo (0,458). O efeito materno (m2) no peso ao nascer variou de baixo a médio, nas raças Carabao, Jafarabadi, Mediterrâneo e Murrah (0,11, 0,17, 0,37, 0,04, respectivamente).Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCassiano, Lisângela Aparecida PinheiroMariante, Arthur da SilvaMcManus, ConceptaMarques, José Ribamar Felipeda Costa, Norton Amador2004-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6793Pesquisa Agropecuaria Brasileira; v.39, n.5, maio 2004; 451-457Pesquisa Agropecuária Brasileira; v.39, n.5, maio 2004; 451-4571678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6793/3849info:eu-repo/semantics/openAccess2014-07-18T16:35:04Zoai:ojs.seer.sct.embrapa.br:article/6793Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-18T16:35:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
