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

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.

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 ...

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 ...

Available phosphorus levels modulate gene expression related to intestinal calcium and phosphorus absorption and bone parameters differently in gilts and barrows [PDF]

Animal Bioscience, 2023
Objective Dietary phytase increases bioavailability of phytate-bound phosphorus (P) in pig nutrition affecting dietary calcium (Ca) to P ratio, intestinal uptake, and systemic utilization of both minerals, which may contribute to improper bone ...

Safety and efficacy of RONOZYME® HiPhos (6‐phytase) as a feed additive for sows and fish [PDF]

EFSA Journal, 2016
Abstract RONOZYME® HiPhos is a preparation of 6‐phytase which is authorised in the EU for use in poultry and pigs. The applicant requested to lower the authorised dose in sows and for a new use of the product as a feed additive for fish. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) considered that the conclusions ...
