Resumo: The objective of this work was to determine crude protein levels on diet of males and females broilers from 22 to 42 days of age. Males (440) and females (440) broilers chickens Hubbard were distributed in a completely randomized design, in order to study five crude protein levels (15%, 17%, 19%, 21% and 23%) in a factorial arrangement. For male broilers, the protein levels had a quadratic effect on weight gain and feed:gain ratio. For females, the effect of protein levels was quadratic on weight gain and linear on feed:gain ratio. The dietary protein levels affected linearly the yield carcass for both sex. The females had higher abdominal fat and breast percentage than the males. The protein level recommended for male broilers is 21.70% and for females is 19.00%.

Oitocentos e oitenta pintos machos e fêmeas de 22 a 42 dias de idade foram distribuídos ao acaso em esquema fatorial 5x2 (níveis de proteína bruta x sexos), com quatro repetições de 22 aves. Os níveis de proteína testados foram 15%, 17%, 19%, 21% e 23%. Houve efeito quadrático dos níveis de proteína no ganho de peso e na conversão alimentar dos machos. Em relação às fêmeas, o efeito foi quadrático no ganho de peso e linear na conversão. A relação entre o rendimento de carcaça e o nível de proteína bruta da ração foi linear e independente do sexo. O consumo de ração, a gordura abdominal e o rendimento de peito foram influenciados apenas pelo sexo. Recomenda-se 21,70% de proteína bruta para os machos e 19,00% para as fêmeas, na fase de crescimento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSabino, Hellen Fernanda NocciolliSakomura, Nilva KazueNeme, RafaelFreitas, Ednardo Rodrigues2004-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6788Pesquisa Agropecuaria Brasileira; v.39, n.5, maio 2004; 407-412Pesquisa Agropecuária Brasileira; v.39, n.5, maio 2004; 407-4121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6788/3844info:eu-repo/semantics/openAccess2014-07-17T17:40:24Zoai:ojs.seer.sct.embrapa.br:article/6788Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-17T17:40:24Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
