Analytical methods
( 1 )
For the identification of acetate in the additive:
—
European Pharmacopoeia monograph 01/2008:20301.
For the crystallographic characterisation of the additive:
—
X-Ray diffraction.
For the determination of total cobalt in the additive, premixtures, compound feed and feed materials:
—
EN 15510 - inductively coupled plasma optical (atomic) emission spectrometry (ICP-AES)
or
—
CEN/TS 15621 - inductively coupled plasma optical (atomic) emission spectrometry (ICP-AES) after pressure digestion.
For the determination of particle size distribution:
—
ISO 13320 - Particle size analysis - Laser diffraction methods.
Ruminants with a functional rumen, equidae, lagomorphs

1 (total)
1.
The additive shall be incorporated into compound feed in the form of a premixture.
2.
Declarations to be made on the labelling of the additive and premixture:
—
Cobalt content
—
‘It is recommended to limit the supplementation with Cobalt to 0,3 mg/kg in complete feed. In this context, the risk for Cobalt deficiency due to local conditions and the specific composition of the diet should be taken into account.’
3.
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.
4.
Declaration to be made in the instructions of use of the compound feed: ‘Protective measures to avoid exposure with Cobalt by inhalation or by dermal route should be taken.’
As soon as a decision on the authorisation of the additive has been taken under Article 9 of Regulation (EC) No 1831/2003 and at the latest on 14 July 2028.
