Resumo: The objective of this study was to obtain genetic marker information in the Gyr breed by analyzing bGH and Pit-1 gene polymorphisms and to verify their association with milk production traits. One sample including 40 Gyr bulls were genotyped at two bGH gene restriction sites (bGH- AluI and bGH-MspI) and at one restriction site in the Pit-1 gene (Pit-1 HinfI). The bGH-MspI(-) allele was favorable for fat milk percentage. The heterozigous Pit-1 HinfI (+/-) bulls were superior for fat milk production, in relation to homozigous Pit-1 HinfI (+/+). The Pit-1 and bGH genes are strong candidates in the dairy cattle QTL search, and zebuine populations are promising samples for this purpose.

Uma amostra de 40 touros da raça Gir foi genotipada, nos dois sítios de restrição no gene bGH (bGH-AluI e bGH-MspI) e em um sítio de restrição no gene Pit-1 (Pit-1 HinfI). O alelo bGH-MspI(-) favoreceu a porcentagem de gordura no leite. Os touros heterozigotos Pit-1 HinfI (+/-) foram superiores quanto à produção de gordura no leite, em relação aos homozigotos Pit-1 HinfI (+/+). Os genes Pit-1 e bGH são fortes candidatos à pesquisa de QTLs em raças leiteiras e populações zebuínas representam uma amostra promissora para esse propósito.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Mattos, Keiko KusamuraDel Lama, Silvia NassifMartinez, Mario LuizFreitas, Ary Ferreira2004-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6749Pesquisa Agropecuaria Brasileira; v.39, n.2, fev. 2004; 147-150Pesquisa Agropecuária Brasileira; v.39, n.2, fev. 2004; 147-1501678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/6749/3805info:eu-repo/semantics/openAccess2014-07-03T17:07:48Zoai:ojs.seer.sct.embrapa.br:article/6749Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-03T17:07:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
