Resumo: In the present experiment the phosphorus availability from dicalcium phosphate and rock phosphate from Patos de Minas, Tapira and Finos de Tapira was determined, by the radiophosphorus dilution technique. Twenty-four male sheep received a semipurified diet and the phosphate sources were added to give 4 g P per day. After two weeks each sheep was injected intravenously with 7,4 MBq of 32P and blood and feces samples were collected at 24 hs intervals for 8 days. The specific activities of plasma and feces were determined. True absorption values were 58.92; 50.85; 47.99 and 42.72% for dicalcium phosphate, Finos de Tapira, Tapira and Patos. Rock phosphate availabilities were high in relation to dicalcium phosphate.

Foram utilizados 24 ovinos, mantidos em dietas semipurificadas, que receberam as fontes de fosfato em quantidades equivalentes a 4 g de P por dia. Após 14 dias, foram injetados 7,4 MBq de 32P em cada animal, e amostras de sangue e fezes foram coletadas a cada 24 horas durante oito dias, para a determinação das atividades específicas. Os valores da absorção real do fósforo foram 58,92; 50,85; 47,99 e 42,72% para o fosfato bicálcico, Finos de Tapira, Tapira e Patos, respectivamente. Em relação ao bicálcico, as rochas fosfáticas apresentaram altos valores de disponibilidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraVitti, Dorinha Miriam Silber SchmidtAbdalla, Adibe LuizSilva Filho, José Cleto da1991-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3446Pesquisa Agropecuaria Brasileira; v.26, n.8, ago. 1991; 1113-1118Pesquisa Agropecuária Brasileira; v.26, n.8, ago. 1991; 1113-11181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3446/779info:eu-repo/semantics/openAccess2012-02-13T17:07:11Zoai:ojs.seer.sct.embrapa.br:article/3446Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-02-13T17:07:11Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
