“…Nelson et al (1968) foram os primeiros a utilizar a enzima fitase produzida por cultivos de Aspergillun ficuum em dietas para frangos, obtendo resultados benéficos. Apesar disso, somente no final da década de 1980, a produção de fitase atingiu escala comercial.…”

O trabalho objetivou determinar a ação da enzima fitase sobre a biodisponibilidade do fósforo do farelo de arroz em dietas de frangos de corte, pela técnica de diluição isotópica. Os tratamentos consistiram de uma dieta sem farelo de arroz integral e sem suplementação de fósforo inorgânico (0,388% de P total), e quatro dietas com 15% de farelo de arroz integral, sem suplementação de fósforo inorgânico (0,56% de P total) e com quatro níveis de fitase (0, 400, 800 e 1,200 FTU/kg). No quinto dia do experimento, cada ave recebeu, via peritonial, 3,5 MBq de 32P. Nos quatro dias subseqüentes, coletaram-se amostras de sangue e excretas para as análises. As perdas endógenas fecais, a absorção aparente e verdadeira de fósforo e o fósforo no plasma aumentaram de maneira significativa (P<0,01) com a utilização de níveis crescentes de fitase. A biodisponibilidade do fósforo foi de 38,06% na dieta com farelo de arroz e sem enzima, e aumentou para 51,54%, 61,31% e 59,54% com a utilização de 400, 800 e 1.200 FTU/kg, respectivamente. Por meio de regressão quadrática, determinou-se a máxima biodisponibilidade de P, que foi de 60,8% com a utilização de 982 FTU/kg. A biodisponibilidade do fósforo do farelo de arroz, determinada por fracionamento, foi de 28,1% e aumentou de forma linear (P<0,05) para 38,3%, 50,2% e 54,0%, com a utilização de 400, 800 e 1.200 FTU/kg.

“…Responses to phytase supplements are dose-dependent, since the release of P per unit phytase decreases as the amount of phytase per unit diet increases . Nelson et al (1968) reported that different cultures of Aspergillus derived phytases had variable effects on P utilisation, with the highest response with Aspergillus niger. However, absolute phytase activities of different supplements were not determined.…”

“…It has been demonstrated that microbial phytase is effective in releasing a significant proportion of the phytate P present in maize and soybean meal (Nelson et al 1968, Simons et al 1990). Microbial phytase has enhanced P utilisation of maizesoybean meal diets in broilers and reduced the amount of P in excreta (Simons et al 1990, Broz et al 1994.…”

“…In cereals and vegetable protein sources between half to three quarters of phosphorus (P) is bound to phytic acid (Eeckhout and De Paepe 1994) and has therefore, only limited availability in poultry (Nelson et al 1968, Simons et al 1990, Kiiskinen et al 1994. Phytic acid does not only limit the utilisation of plant P, but also complexes with various cations, e.g.…”

The present study was carried out to determine the effect of two microbial phytases, Aspergillus niger (FINASE ® FP-500, 291 PU (phytase units)/g) and Trichoderma reesei phytase (FINASE ® P, 5880 PU/g) on phosphorus (P) and calcium (Ca) utilisation and ileal P and Ca digestibility in broiler chickens fed diets based on maize and soybean meal. A total of 96 Ross broiler chickens housed four birds to a cage were used. Four dietary treatments consisted of a positive control supplemented with dicalcium phosphate (17 g/kg), a negative control without inorganic P, basal diet without inorganic P supplemented with Aspergillus niger phytase (2.6 g/kg) and basal diet without inorganic P supplemented with Trichoderma reesei phytase (0.13 g/kg). Both phytases provided 750 PU/kg feed. P retention per unit intake was lowest and P excretion highest in birds fed the positive control diet with inorganic P (P<0.001). Both phytases clearly decreased P excretion (P<0.05) and increased P utilisation (P<0.001) compared to the negative control treatment. No differences were found between Aspergillus and Trichoderma phytases in P retention. Phytase supplementations also increased apparent ileal digestibility of P compared to the negative control treatment (P<0.05). Phytase supplementation also increased Ca retention per unit intake (P<0.001). In conclusion, both microbial phytases were equally effective in improving utilisation of P in broiler chickens fed maize-soybean meal diets.
