Efeito da fitasa sobre biodisponibilided de fosforo em dietas com cascara de arroz em frango


Availability of phytate phosphorus was measured in corn [maize], soyabean meal and rice bran (RB) after the addition of phytase. 264 broilers in heated (0 to 21 days) and cold batteries (22 to 49 days), were used. Six treatments used in the experiment included two without RB (with or without 900 phytase units (FTU)/kg diet) and four with RB (15%) and increasing levels of phytase (0, 300, 600 and 900 FTU/kg diet). Phytase increased the availability of phytase phosphorus. Inclusion of RB in the diets decreased the percentage of ash in tibia. The increase in phytase level up to 900 FTU/kg diet with RB showed a linear response for weight gain, feed intake, feed:gain ratio, percentage of ash in the tibia and reduction of phosphorus in the excreta.
