Ileal and total tract digestibility of energy and nutrients in pig diets supplemented with a novel consensus bacterial 6-phytase variant. [PDF]

J Anim Sci, 2022
AbstractAn experiment was conducted to test the hypothesis that increasing levels of a novel phytase increases the apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of nutrients in diets fed to young pigs. A negative control (NC) diet based on corn, soybean meal, and canola meal that contained approximately 0.83% phytate (

Comparison of mucosal phosphatase activity, phytate degradation, and nutrient digestibility in 3-week-old turkeys and broilers at different dietary levels of phosphorus and phytase

Poultry Science, 2023
: A comparison between 3-wk-old female turkeys (B.U.T. 6) and broilers (Ross 308) was performed to study the effects of species, dietary P, Ca, and phytase levels on gut mucosal phosphatase activity, myo-inositol hexakisphosphate (InsP6) degradation ...

Safety and efficacy of APSA PHYTAFEED^® 20,000 GR/L (6-phytase) as a feed additive for pigs for fattening. [PDF]

EFSA J, 2020
Following a request from the European Commission, the EFSA Panel on Additives and products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of APSA PHYTAFEED ® 20,000 GR/L (6-phytase) as a feed additive for pigs for fattening.

Inositol and gradient phytase supplementation in broiler diets during a 6-week production period: 2. Effects on phytate degradation and inositol liberation in gizzard and ileal digesta contents1

Poultry Science, 2021
An experiment was conducted to evaluate effects of dietary phytase and inositol supplementation on phytate degradation in gizzard and ileal digesta contents of broilers from 1 to 43 d of age.

In Vitro Characterization of a Novel Consensus Bacterial 6-Phytase and One of its Variants

Current Biochemical Engineering, 2020
Background:: Microbial phytases are added to animal feed to hydrolyze phytic acid (myoinositol hexakisphosphate, IP6) and phytate (salt of phytic acid) increasing phosphorus bioavailability. Novel phytases with enhanced bio-efficacy are being developed.

Assessment of a bacterial 6-phytase in the diets of broiler chickens

Poultry Science, 2013
Two 21-d broiler experiments were conducted to assess the efficacy of a bacterial 6-phytase expressed in Aspergillus oryzae on growth performance, nutrient utilization, and intestinal molecular markers. Two hundred forty birds in 5 treatments (experiment 1) or 256 birds in 4 treatments (experiment 2) were used.

Phytases Improve Myo-Inositol Bioaccessibility in Rye Bread: A Study Using an In Vitro Method of Digestion and a Caco-2 Cell Culture Model

Food Technology and Biotechnology, 2015
Preparations of 6-phytase A (EC 3.1.3.26) and phytase B (acid phosphatase, EC 3.1.3.2) were applied alone and combined in the preparation of dough to estimate their catalytic potential for myo-inositol liberation from rye flour in the breadmaking ...

Degradation of Phytate by the 6-Phytase from Hafnia alvei: A Combined Structural and Solution Study

PLoS ONE, 2013
Phytases hydrolyse phytate (myo-inositol hexakisphosphate), the principal form of phosphate stored in plant seeds to produce phosphate and lower phosphorylated myo-inositols. They are used extensively in the feed industry, and have been characterised biochemically and structurally with a number of structures in the PDB.
