Analytical method
( 2 )
Identification and enumeration of Bacillus licheniformis ATCC 53757 in the feed additive, premixtures and feedingstuffs:
—
Identification: Pulsed field gel electrophoresis (PFGE)
—
Enumeration: Spread plate method using tryptone soya agar — EN 15784
Quantification of protease in the feed additive, premixtures and feedingstuffs:
—
Colorimetric method measuring para-nitroaniline (pNA) released by the enzymatic reactionof protease on Suc-Ala-Ala-Pro-Phe-pNA substrate at 37 °C

In the directions for use of the additive and premixture, indicate the storage temperature, storage life and stability to pelleting.
2.
Recommended minimum dose 500 mg of additive/kg of complete feed.
3.
For users of the additive and premixtures in a feed business, operational procedures and appropriate organisational measures shall be established to address hazards by inhalation, dermal contact or eye contact. Where the dermal, inhalator or eye exposure cannot be reduced to an acceptable level by these procedures and measures, the additive and premixtures shall be used with appropriate personal protective equipment
4.
The use is permitted in feed containing the following authorised coccidiostats: diclazuril, nicarbazin, decoquinate, semduramycin sodium, lasalocid sodium, monensin sodium robenidine hydrochloride, maduramicin ammonium, narasin or salinomycin sodium
5.
Recommended use in protein-reduced rations.
