Resumo: | Effect of nonphytate phosphorus and phytase levels on broiler femur. This experiment was carried out to evaluate the effect of nonphytate phosphorus (NPP) and phytase levels on the weight, morphometry and weight/length index (WLI) of broiler femurs at 21 and 42 days of age. One thousand, two hundred chicks were allocated in a completely randomized design and 4 x 3 factorial arrangement (NPP x phytase levels), with four replicates. The NPP levels, at each phase were of 0.45, 0.37, 0.29 and 0.21% in the initial phase, 0.41, 0.33, 0.25 and 0.17% in the growth phase, and of 0.37, 0.29, 0.21 and 0.13% in the final phase. The phytase levels used were 0, 500 and 1000U/kg of diet. At 21 and 42 days of age, 48 birds were sacrificed for femur collection. At 21 days, there was no effect (P > 0.05) of NPP x phytase interaction on bone parameters, but the NPP reduction decreased (P < 0.05) the weight, length and WLI of the femurs, and the inclusion of 500U/kg of phytase improved (P < 0.05) the weight and WLI of the bones. At 42 days of age, NPP x phytase interaction was significant (P < 0.05) for the weight and length, and birds fed diets with no phytase had femurs that were lighter and shorter when the lowest NPP levels were evaluated. However, the inclusion of 500 or 1000U/kg of phytase produced weights and lengths similar to those produced by treatment with recommended NPP levels, and the lower NPP levels evaluated caused a reduction (P < 0.05) in the diameter and WLI of femurs. It was concluded that diets with 0.29, 0.25 or 0.21% of NPP, with 500 U/kg of phytase, could be used with no negative effect on the femur quality in broilers from one to 42 days of age. |

Foram utilizados 1200 pintos de corte alojados em delineamento inteiramente casualizado e arranjo fatorial 4 x 3 (níveis de FNF x níveis de fitase), com quatro repetições. Os níveis de FNF, em cada fase, foram de 0,45; 0,37; 0,29 e 0,21% na fase inicial; 0,41; 0,33; 0,25 e 0,17% na fase de crescimento e de 0,37; 0,29; 0,21 e 0,13% na fase final. Os níveis de fitase utilizados foram 0,500 e 1000U/kg de dieta. Aos 21 e 42 dias de idade, 48 aves foram sacrificadas para a retirada dos fêmures. Aos 21 dias, não houve efeito (P > 0,05) da interação FNF x fitase sobre parâmetros ósseos, porém a redução do FNF dietético diminuiu (P < 0,05) o peso, o comprimento e o IPC dos fêmures e a inclusão de 500U/kg de fitase melhorou (P < 0,05) o peso e o IPC dos ossos. Aos 42 dias de criaçãi, a interação FNF x fitase foi significativa (P < 0,05) para peso e comprimento dos fêmures, em que aves que ingeriram dietas sem fitase tiveram fêmures mais leves e mais curtos quando o menor nível de FNF foi avaliado, porém, a inclusão de 500 ou 1000U/kg de fitase tornou o peso e o comprimento similares aos do tratamento com níveis recomendados de FNF e o menor nível de FNF avaliado, promoveu redução (P < 0,05) no diâmetro e no IPC dos fêmures. Concluiu-se que dietas com 0,29, 0,25 e 0,21% de FNF, suplementadas com 500U/kg de fitase, podem ser usadas sem prejuízos para a qualidade do fêmur dos frangos de corte de um a 42 dias de idade.Universidade Federal de Santa Catarina2009-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2009v22n1p8110.5007/2175-7925.2009v22n1p81Biotemas; v. 22 n. 1 (2009); 81-852175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2009v22n1p81/18722Copyright (c) 2011 Luana Martins Schaly, Bruno Nunes Gonçalves, Maria Cristina de Oliveira, Antônio Carlos Laurentiz, Otto Mack Junqueirainfo:eu-repo/semantics/openAccessMartins Schaly, LuanaGonçalves, Bruno Nunesde Oliveira, Maria CristinaLaurentiz, Antônio CarlosJunqueira, Otto Mack2018-03-07T17:29:06Zoai:periodicos.ufsc.br:article/20520Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2018-03-07T17:29:06Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
