Analytical method

( 1 )

For the identification of L-threonine in the feed additive:

—

Food Chemical Codex ‘L-threonine monograph’

For the determination of threonine in the feed additive:

—

Ion-exchange chromatography coupled to post-column derivatisation and optical detection (IEC-VIS/FLD) – EN ISO 17180

For the determination of threonine in premixtures:

—

Ion-exchange chromatography coupled to post-column derivatisation and optical detection (IEC-VIS/FLD) – EN ISO 17180 or

—

Ion-exchange chromatography coupled to post-column derivatisation and optical detection (IEC-VIS) – Commission Regulation (EC) No 152/2009  ( 2 )

For the determination of threonine in compound feed:

—

Ion-exchange chromatography coupled to post-column derivatisation and optical detection (IEC-VIS) – Regulation (EC) No 152/2009

For the determination of threonine in water:

—

Ion-exchange chromatography coupled to post-column derivatisation and optical detection (IEC-VIS or IEC-VIS/FLD)

All animal species

–

–

–

1.

In the directions for use of the additive and premixtures, the storage conditions, the stability to heat treatment and in water shall be indicated.

2.

The additive may be used via water for drinking.

3.

Feed business operators shall ensure that L-threonine is rumen protected, when fed to ruminants.

4.

The labelling of the additive and premixtures shall indicate the following:

—

‘The supplementation with L-threonine, in particular via water for drinking, shall take into account all essential and conditionally essential amino acids in order to avoid imbalances.’

5.

For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from their use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal skin, eye and breathing protective equipment.
