Scientific Opinion on the modification of the terms of authorisation of Quantum™ (6‐phytase) as a feed additive for turkeys for fattening

EFSA Journal, 2012
Abstract The additive Quantum™ is an enzyme preparation containing 6‐phytase produced by fermentation of a genetically modified strain of the yeast Pichia pastoris. The efficacy and safety of this product for chickens for fattening, laying hens, turkeys for fattening, ducks for fattening and piglets (weaned), including the assessment of the safety for ...

Effect of a biosynthetic bacterial 6-phytase on the digestibility of phosphorus and phytate in midlactating dairy cows. [PDF]

J Anim Sci, 2023
AbstractThe effect of a biosynthetic bacterial 6-phytase (PhyG) on the digestibility and excretion of crude protein (CP), phosphorus (P), and phytate-P (PP) in midlactating dairy cows was investigated. Thirty Holstein-Friesians were assigned to three treatments with 10 cows per treatment in a randomized block design.

A Novel Bacterial 6-Phytase Improves Productive Performance, Precaecal Digestibility of Phosphorus, and Bone Mineralization in Laying Hens Fed a Corn-Soybean Meal Diet Low in Calcium and Available Phosphorus. [PDF]

J Poult Sci, 2023
Exogenous phytases are commonly added to low-phosphorus and low-calcium diets to improve P availability and reduce P excretion by poultry. This study investigated the effect of supplementation with a novel bacterial 6-phytase on egg production, egg ...

Microbial Phytase and Phosphorus Utilization by Broiler Chickens

Scientific Papers Animal Science and Biotechnologies, 2023
The aim of study was to investigate the mathematical and statistical assesment of the micorbial 6-phytase efficacy on phosphorus utilization at broiler chickens Cobb 500. Broiler chickens fed commercial feed mixtures based on soyabean-maize meal.

Effects of supplemental hybrid bacterial 6-phytase in low-energy, inorganic phosphorus-free hen diets on laying performance, egg quality, and bone strength. [PDF]

PLoS One
A 22-week trial was conducted to assess the effects of replacing inorganic phosphorus (P) with two levels of a hybrid bacterial 6-phytase in low-energy diets for laying hens, from 23 to 44 weeks of age.

Modeling improvements in digestible amino acids by a consensus bacterial 6-phytase variant in grower pigs. [PDF]

J Anim Sci
Abstract Data from 8 datasets generated from 5 independent experiments that determined the effects of a consensus bacterial 6-phytase variant (PhyG) on apparent ileal digestibility (AID) of amino acids (AA) in growing pigs (~21 to 45 kg body weight) were combined and modeled to test the hypothesis that the phytase results in significant ...
