The Feed Additives (Authorisations) (Wales) Regulations 2023

Regulation 3(1)

SCHEDULE 10Renewal of authorisation of a preparation of 6-phytase (EC 3.1.3.26) produced from Trichoderma reesei (CBS 122001) (identification number 4a12) as a feed additive for pigs, poultry for breeding, poultry for fattening, and poultry for laying

The preparation of 6-phytase (EC 3.1.3.26) specified in the table, belonging to the additive category “zootechnical additives” and to the functional group “digestibility enhancers”, is authorised as an additive in animal nutrition subject to the conditions set out in the table(1).

(1)

Enzyme activity expressed in PPU units, where 1 PPU is the amount of enzyme which liberates 1 micromole (μmol) of inorganic phosphate from sodium phytate per minute at pH 5.0 and 37°C.

(2)

CAS Registry Number® assigned to this preparation by the Chemical Abstracts Service https://www.cas.org/cas-data/cas-registry.
