Resumo: | It was evaluated the mineral content, density, weight, morphometry and breaking strength of tibiae in broilers fed diets containing phytase and reduced nonphytate phosphorus levels (NPP). The experimental design was completely randomized and factorial arrangement 2 x 3 with two phytase levels (0 and 25U/kg) and three NPP levels (100, 85 and 70% of the requirements) in a total of six treatments and five replicates. There was no effect of NNP levels and/or phytase on phosphorus and ashes levels, weight, length and diameter. Interaction NPP x phytase was significant to Ca content that was lower in tibiae of birds fed diets with 70% of NPP and with no phytase. Proximal epiphysis density decresead due the reduction of NPP and increased with phytase inclution in the diet. There was effect of the interaction NPP x phytase to diaphysis, distal epiphysis and mean densities. Breaking force decreasead in birds fed diets with 70% of NPP. Diets with 85% of NPP requirements, supplemented with 25U/kg of phytase, can be used with no negative effects on mineral content, density, weight, morphometry and breaking strength of broilers tibiae. Key words: bone density, bone mineralization, breaking strength |

Key words: bone density, bone mineralization, breaking strengthAvaliou-se teor de minerais, densidade, peso, morfometria e resistência à quebra de tíbias de frangos alimentados com dietas contendo fitase e níveis reduzidos de fósforo disponível (Pd). O delineamento foi inteiramente casualizado em esquema fatorial 2 x 3, com dois níveis de fitase (0 e 25 UFT kg-1) e três níveis de Pd (100, 85 e 70% das exigências), totalizando seis tratamentos e cinco repetições. Não houve efeito dos níveis de Pd e/ou fitase sobre os teores de fósforo e de matéria mineral, peso, comprimento e diâmetro. A interação Pd x fitase foi significativa para teor de Ca, que foi menor nas tíbias das aves que consumiram dietas com 70% de Pd sem fitase. A densidade da epífise proximal diminuiu pela redução de Pd e aumentou com a inclusão da fitase na dieta. Houve efeito da interação Pd x fitase para densidades da diáfise, epífise distal e média. A resistência óssea diminuiu em aves alimentadas com dietas com 70% das exigências de Pd. Podem-se adotar dietas com 85% das exigências de Pd, suplementadas com 25 UFT kg-1 de fitase, sem efeitos negativos sobre a qualidade óssea.Editora da Universidade Estadual de Maringá2008-11-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/49610.4025/actascianimsci.v30i3.496Acta Scientiarum.
