efficacy of phytase preparations to improve p availability in young turkeys
Authors
abstract
phytate phosphorus of plant ingredients is not substantially available to poultry because of the lack of endogenous phytase enzymes in their gastrointestinal tract. there are substantial differences among broilers, turkeys, and ducks in terms of plant p utilization. we studied whether the availability of p is different for two phytase enzymes in turkeys. finase and a new phytase product developed recently were tested in 3 to 5 week old turkeys. the efficacy of finase and the new phytase were determined on the basis of p balance and tibia data. a low p maize soybean meal based diet was supplemented at 0, 250 and 500 ftu/kg levels of finase and 0, 250, 500 and 750 ftu/kg of the new phytase. excretions were collected in a balance trial and tibia parameters were obtained after the turkeys had received their respective diets for 17 days. utilization of p from the basal diet was 35.5% which significantly improved by finase to a maximum of 47.3% and by the new phytase to a maximum of 48.7% at the highest level of supplementation. the utilization of ca did not improve. tibia ash concentration improved by finase and the new phytase supplementation. it is concluded that the finase and the new phytase efficiently improve the utilization of p in turkeys and may help protect the environment by causing a reduction in excretion p.

A total of 600 male BUT Big 6 turkeys were randomly allocated to 60 pens, 10 birds in each. Each of six treatment groups consisted of 10 pens (replicates), 100 birds in each treatment, at a stocking density of 2.5 birds per m. The turkeys were reared until 112 days (16 weeks) of age, and they were fed diets based on corn, soybean meal and wheat. Group I (positive control PC) received a diet wit...

Stem/progenitor cell based therapeutic approach in our daily routine clinical practice, has been elusive dream in medical sciences and improvement of stem cell homing as one of major challenges in cell therapy programs, has been considered a promising milestone. It has been proved that stem/progenitor cells exhibit a homing response to injured tissues/organs, mediated by interactions of chemoki...

Male broilers (n = 416) were used to compare the efficacy of providing dietary phytase either as a commercial supplement or as a recombinant protein in transformed soybean. From 7 to 21 d of age, broilers were fed a basal diet containing 0.20% nonphytate P (nP) with additional supplementation by fungal phytase as Natuphos or as raw transformed soybeans expressing recombinant phytase at 400, 800...
