“…6). (Nelson et al, 1971;Applegate et al, 2003;Augspurger et al, 2003), os quais indicaram que resultados para cinzas ósseas, tanto em porcentagem como em miligramas, podem ser utilizados para estimar o P liberado da molécula de fitato pela fitase. Augspurger et al (2003) mostraram que a utilização de fitase de origem fúngica com inclusões de 500 e 1000 FTU/kg liberou de 0,026 a 0,048% de P, e a fitase bacteriana (E. coli) com inclusão de 500 FTU/kg liberou 0,125% de P. Os resultados obtidos pela fitase bacteriana (E. coli) utilizando-se menores níveis de inclusão (66, 99 e 131 FTU/kg de ração) liberaram, respectivamente, 0,048, 0,049 e 0,062% de P (Fig.…”

RESUMOFoi avaliada a eficiência de uma fitase (FT) bacteriana na liberação de fósforo fítico utilizando-se curvas de calibração para características ósseas e de desempenho em frangos de corte. O delineamento experimental foi inteiramente ao acaso, com seis tratamentos e seis repetições até 28 dias de idade. O tratamento-controle foi uma dieta à base de milho e farelo de soja deficiente em fósforo (P). Dois tratamentos corresponderam às dietas basais acrescidas de P suplementar, 0,05% e 0,10%, e os outros à dieta basal com 66, 99 e 131 FTU/kg de ração. A curva padrão é definida pelo efeito da adição de P suplementar consumido sobre características ósseas e de desempenho, e os resultados dos tratamentos com fitase são confrontados com a curva para cálculo de P liberado. A adição de P suplementar influenciou o ganho de peso, o peso vivo e o consumo de ração de forma quadrática, bem como miligramas de cinzas ósseas de forma linear. A curva padrão adotada foi da variável miligramas de cinzas ósseas, pois a resposta linear melhor descreve a curva. As inclusões de 66, 99 e 131 FTU/kg liberaram, respectivamente, 0,048%, 0,049% e 0,062% de P. A fitase bacteriana é eficiente na liberação de fósforo fítico e possui viabilidade econômica.Palavras-chave: frango de corte, fósforo disponível, cinzas ósseas, curva de calibração ABSTRACT

“…This holds promise for reduced phosphorus in effluents and reduced phosphorus pollution. Use of commercial phytase has been reported to improve phytate P bioavailability in poultry, swine, and fish, which should decrease the amount of phosphorus excreted (Nelson et al 1971, Simons et al 1990, Crowell et al 1993, Rodehutscord et al 1995, Schafer et al 1995, Jackson et al 1996, Lanari et al 1998, Veilma et al 1998, Veilma et al 2000. The increased nutrient utilization due to the addition of phytase in the diet has yet to be widely studied in fish.…”

An experiment was conducted to investigate the effect of phytase supplementation on weight gain, phosphorus and protein digestibility and retention in Japanese flounder (Paralichthys olivaceus) fed a soybean meal (SBM)-containing diet. Six levels of phytase-supplemented diets containing 0, 150, 300, 450, 900 and 1500 FTU (phytase unit)/100g diet were assigned to triplicate tanks and fed to Japanese flounder (20 fish/ tank, initial average weight 151.4 g) for 40 days. The increase of soluble phosphorus and decrease of phytic acid remained relatively constant for all levels receiving the 300 FTU diet and greater. Significantly (P<0.05) greater weight gain and higher feed conversion ratios (FCR) were observed in fish fed diets supplemented at 300 FTU or greater compared to the control (0 FTU) diet. Significantly (P<0.05) improved apparent protein and phosphorus digestibility, as well as serum calcium concentration were found in fish fed the 300 FTU diet. All Effects of phytase addition on P utilization in Japanese flounder diets supplemented at 300 FTU or greater also showed a significantly (P<0.05) improved concentration of bone calcium and zinc. The 150 FTU inclusion level showed only better protein and phosphorus retention, bone phosphorus and magnesium than the control (0 FTU) diet. Therefore, this study indicated that supplementation of phytase is effective and that the 300 FTU/100g SBM-containing diet resulted in the maximum release of soluble phosphorus, and as a consequence improved weight gain, FCR, bone minerals, phosphorus and protein digestibility and retention in Japanese flounder.
