Resumo: An experiment was carried out with broilers in the initial (7 - 28 days), final (28 - 49 days) and total phase (7 - 49 days), testing three rock phosphate (patos, goiás and tapira), with bicalcium as a standart. In each source the diets were calculated to have 0%; 0.15%; 0.30% and 0.45% of supplemented P, with fixed Ca; P ratio, in isonitrogenous and isoenergetic diets. The pullets were mantained in electric batteries with ten broilers by parcel, in a completely randomized design. The variables were: total weight gain (TWG), feed: gain ratio (FGR), tibial ash (TA), tibial phosphorus (TP) and plasma phosphorus (PP). Goiás phosphate was poorer (P<0.05) than other, and there were no differences (P>0.05) between those phosphates. Goiás phosphate reduced the performance as it was included in the ration. Based on TA the available phosphorus in patos and tapira phosphate range between 54 and 76%. It was concluded that broilers receiving bicalcium, patos and tapira phosphates showed a similar performance, and goiás phosphate reduced the performance as it was included in the ration.

Para cada fonte, as dietas foram calculadas para ter 0%; 0,15%; 0,30% ou 0,45% de fósforo (P) suplementar, mantendo-se constante a relação Ca: P, sendo elas isoprotéicas e isoenergéticas. Os pintos foram alojados em baterias com aquecimento elétrico, tendo dez aves por parcela. O delineamento utilizado foi o inteiramente casualizado. As variáveis estudadas foram: ganho de peso total (GPT), conversão alimentar (CA), percentagem de cinza na tíbia (CT), percentagem de fósforo na tíbia (PT), e fósforo no plasma sanguíneo (PP). Constatou-se inferioridade (P<0,05) do fosfato goiás em relação aos demais, não havendo diferenças significativas (P>0,05) entre estes. O fosfato goiás piorou o desempenho à medida que foi incluído na ração. A estimativa de P disponível, baseada na CT, situou-se entre 54% e 76% para os fosfatos patos e tapira. Concluiu-se que houve similaridade no desempenho entre as aves que receberam os fosfatos bicálcico, patos e tapira, e que o goiás piorou o desempenho à medida que foi incluído na ração.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBellaver, ClaudioGuidoni, Antônio L.Albino, Luiz F.
