Resumo: | Although phytase has been researched, new enzymes have been produced, leading to different animal responses. In this scenario, the present study proposes to evaluate the inclusion of a bacterial phytase produced by Escherichia coli in broiler diets based on corn and soybean meal, with or without nutrient reductions, on the performance, nutrient digestibility, phosphorus bioavailability, and bone minerals of those animals and on the economic viability of this practice. A total of 896 male broiler chickens were distributed into 32 experimental units, each housing 28 broilers. The experiment was set up as a completely randomized design with four treatments (Positive Control (PC)- diet meeting the nutritional requirements of the broiler chickens; Negative Control (NC) with reductions of 100kcal/kg of ME, 0.14% avP and 0.11% tCa; NC + phytase (500 FTU/kg); PC + phytase (500FTU/kg)) and 8 replicates. Phytase increased (p < 0.05) feed intake and body weight gain and improved feed conversion ratio in starter (1 to 21 days) and total (1 to 42 days) phases, respectively, compared with Negative Control diet without supplementation. The Negative Control + phytase diet also led to a feed intake similar to Positive Control in the starter and total phases. The inclusion of phytase without nutrient reductions improved (p < 0.05) feed conversion ratio in the starter phase, compared to Positive Control diet. There was an increase (p < 0.05) in the digestibility of dry matter, crude protein and phosphorus and in apparent digestible energy in the Negative Control + phytase diet compared to the Negative Control diet. Phytase supplementation increased (p < 0.05) the digestibility of crude protein, calcium and phosphorus, and apparent digestible energy compared to Positive Control diet. Ash, phosphorus, and calcium contents were higher in the Negative Control + phytase diet compared with those observed in the Negative Control diet without enzyme (p < 0.05). The Positive Control + phytase diet provided higher ash contents (p < 0.05), but calcium and phosphorus deposition was similar to those obtained with Positive Control diet. Phytase inclusion allows for a reduction in the diet cost per ton of produced feed. In conclusion, dietary supplementation with bacterial phytase produced from Escherichia coli for broiler chickens is recommended, as it provided increases in production performance, nutrient digestibility, and energy metabolizability and a reduction in the diet cost. |

Nesse sentido, o presente estudo teve como objetivo avaliar a inclusão de fitase bacteriana produzida por Escherichia coli em dietas à base de milho e farelo de soja, com ou sem redução de nutrientes sobre o desempenho, digestibilidade dos nutrientes, biodisponibilidade de fósforo, minerais ósseos e viabilidade econômica. Foram distribuídos 896 frangos de corte machos em 32 unidades experimentais, cada unidade constituída por 28 frangos. O delineamento foi inteiramente casualizado com quatro tratamentos (Controle Positivo (CP) - dieta que satisfaz os requisitos nutricionais das aves; Controle Negativo (CN) - reduções de 100 kcal/kg EM; 0,14% avP e 0,11% tCa); CN + fitase (500 FTU/kg); CP + fitase (500 FTU/kg)) e 8 repetições. A fitase aumentou (p < 0,05) o consumo de ração, o ganho de peso médio e melhorou a conversão alimentar nas fases inicial (1 a 21 dias) e total (1 a 42 dias), respectivamente, em comparação com a dieta Controle Negativo, sem suplementação. O Controle Negativo + fitase também apresentou consumo de ração semelhante ao Controle Positivo nas fases inicial e total. A inclusão da fitase sem redução dos requerimentos nutricionais (Controle positivo + fitase) melhorou (p < 0,05) a conversão alimentar na fase inicial, em comparação com a dieta Controle Positivo. Houve aumento na digestibilidade de matéria seca, proteína bruta, energia digestível aparente e fósforo, respectivamente, em Controle Negativo + fitase em comparação com a dieta controle negativo. A suplementação de fitase aumentou a digestibilidade de proteína bruta, energia digestível aparente, cálcio e fósforo, em comparação com a dieta de Controle Positivo. Os teores de cinzas, fósforo e cálcio foram maiores no Controle Negativo + fitase comparados com os da dieta Controle Negativo, sem enzima. No Controle Positivo + fitase observou-se maior teor de cinzas, mas a deposição de cálcio e fósforo foi semelhante em relação ao Controle Positivo. A inclusão da fitase permitiu redução nos custos da dieta/tonelada de alimento produzido. Em conclusão, recomenda-se a suplementação dietética com fitase bacteriana produzida por Escherichia coli para frangos de corte é recomendada, pois houve aumento no desempenho produtivo, maior digestibilidade e metabolizabilidade dos nutrientes e redução no custo das dietas.UEL2019-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3270610.5433/1679-0359.2019v40n2p767Semina: Ciências Agrárias; Vol. 40 No. 2 (2019); 767-780Semina: Ciências Agrárias; v. 40 n. 2 (2019); 767-7801679-03591676-546Xreponame:Semina.
