Resumo: The objective of this work was to evaluate the performance and the bone mineralization of broilers, at 1 to 21 days of age, and the bioavailability of phosphorus in commercial phosphates utilized inthe broilers feeding. One thousand and eight male chickens of one day old were distributed in a completely randomized design, in fourteen treatments, with six replications of twelve birds each. Phosphates evaluated were: defl uorinated phosphate, monocalcium B, dicalcium A, dicalcium B and dicalcium C, with two levels of available phosphorus (0.30 and 0.40%). For the evaluation of the relative bioavailability, the abscissa technique was used, and the monocalcium A phosphate was taken as standard (value of 100%), with four levels of available phosphorus: 0.25, 0.35, 0.45 and 0.55%. All the phosphates with 0.40% of available phosphorus levels propitiated similar weight gain to broilers. The monocalcium B resulted in higher bone mineralizationof broilers than the defl uorinated phosphate. The different phosphorus sources presented few differences in the values of relative bioavailability of phosphorus, with better results for the monocalcium B and with highersensibility response for bone ashes than for body weight gain.

Mil e oito pintos machos de um dia de idade foram distribuídos em 14 tratamentos, com 6 repetições de 12 aves cada, em delineamento inteiramente ao acaso. Os fosfatos avaliados foram o defl uorizado, monocálcico B, bicálcico A, bicálcico B e bicálcico C, com dois níveis de fósforo disponível (0,30 e 0,40%). Foi adotada a técnica da abscissa e o fosfato monocálcico A como padrão (valor 100%), com quatro níveis de fósforo disponível: 0,25, 0,35, 0,45 e 0,55% para o cálculo da biodisponibilidade relativa. Todos osfosfatos com 0,40% do fósforo disponível proporcionaram às aves ganho de peso semelhante. Houve maior mineralização óssea das aves com o fosfato monocálcico B, comparado ao fosfato defl uorizado. As fontes defósforo apresentaram pequenas diferenças nos valores de biodisponibilidade relativa, com melhores resultados quanto ao monocálcico B e com maior sensibilidade de resposta da variável cinzas ósseas, em relação ao ganho de peso.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraQueiroz, Livya Stefane Borges deBertechini, Antonio GilbertoRodrigues, Paulo BorgesGuerreiro, Mário César2008-10-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/616Pesquisa Agropecuaria Brasileira; v.43, n.10, out. 2008; 1421-1427Pesquisa Agropecuária Brasileira; v.43, n.10, out. 2008; 1421-14271678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/616/5532https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/616/425info:eu-repo/semantics/openAccess2014-07-17T19:21:53Zoai:ojs.seer.sct.embrapa.br:article/616Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-17T19:21:53Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
