Identification number of the additive

4a32

Authorisation holder

Huvepharma EOOD

Additive category

Zootechnical additives

Functional group

Digestibility enhancers

Additive composition

Preparation of 6-phytase (EC 3.1.3.26) produced by Komagataella phaffii DSM 32854 with a minimum activity of 5000 FTU (1)/g in granular, coated or liquid forms

Characterisation of the active substance(s)

6-phytase (EC 3.1.3.26) produced by fermentation with Komagataella phaffii DSM 32854

Analytical methods(2)

For quantification of phytase activity in the feed additive:

  • Colorimetric method based on the enzymatic reaction of phytase on the phytate (VDLUFA 27.1.4(3)).

For quantification of phytase activity in premixtures:

  • Colorimetric method based on the enzymatic reaction of phytase on the phytate (VDLUFA 27.1.3(4)).

For quantification of phytase activity in feed materials and compound feed:

  • Colorimetric method based on the enzymatic reaction of phytase on the phytate (BS EN ISO 30024:2009(5)).

Species or category of animal

  • All poultry species

  • Ornamental birds

  • Piglets

  • Pigs for fattening

  • Sows

  • Minor porcine species for fattening or reproduction

Maximum age

None

Minimum content(6)

250 FTU/kg

Maximum content(6)

None

Other provisions

In the directions for use of the feed additive and premixtures, the storage conditions and stability to heat treatment must be indicated.

(1)

FTU = phytase enzyme units. One FTU is the amount of enzyme that releases 1 micromole (µm) of inorganic phosphate from sodium phytate per minute under reaction conditions of pH 5.5 and 37°C.
