Safety and efficacy of OPTIPHOS® (6‐phytase) as a feed additive for finfish [PDF]

EFSA Journal, 2017
The additive OPTIPHOS ® is a preparation of 6-phytase that is authorised for use in avian species, weaned piglets, pigs for fattening and sows. The applicant seeks for an extension of use of the product to finfish, at a dose range between 250 and 1,000 OTU/kg feed. The FEEDAP Panel concluded in a previous opinion that there are no concerns for consumer

Modeling improvements in ileal digestible amino acids by a novel consensus bacterial 6-phytase variant in broilers. [PDF]

Poult Sci, 2022
Data from 13 datasets from 4 trials on the effect of a novel consensus bacterial 6-phytase variant (PhyG) on the apparent ileal digestibility (AID) of amino acids (AA) in broilers were used to model AID AA responses. The datasets were obtained from 3 trial locations (New Zealand, Australia and United States) and collectively incorporated variations in ...

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.

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.

Evaluation of a novel hybrid 6-phytase using an updated phosphorus deficiency model in broiler chickens

Canadian Journal of Animal Science, 2021
One-day-old broiler chicks were used to investigate the optimal age to start feeding phosphorus (P)-deficient (PD) diets with two non-phytate P (nPP) concentrations in experiment 1, and 7-d-old broiler chicks were used to determine P equivalency of a hybrid 6-phytase to inorganic P in monocalcium phosphate (MCP) in experiment 2.

Enhanced Farrowing Efficiency and Sow Performance with <i>Escherichia coli</i>-Derived 6-Phytase Supplementation During Late Gestation and Lactation. [PDF]

Animals (Basel)
Phytase releases phosphorus from phytate and may confer extra-phosphoric benefits in sows. We tested whether Escherichia coli-derived 6-phytase during late gestation and lactation improves sow and litter outcomes. In a randomized complete block trial, 186 TN70 sows received a phytase-free positive control (adequate Ca and available P) or Ca- and P ...
