Analytical methods(3)

For the identification of carbonate in the additive:

  • European Pharmacopoeia monograph 20301(4)

For the crystallographic characterisation of the additive:

  • X-Ray diffraction

For the determination of total cobalt in the additive, premixtures, feed materials and compound feed:

  • Inductively coupled plasma optical (atomic) emission spectrometry (ICP-AES) in accordance with BS EN 15510: 2017(5); or

  • Inductively coupled plasma optical (atomic) emission spectrometry (ICP-AES) after pressure digestion in accordance with BS EN 15621:2017(6)

For the determination of particle size distribution:

  • Particle size analysis, laser diffraction methods in accordance with BS ISO 13320:2020(7)

Species or category of animal

Minimum content

No minimum

Maximum content

1 (total)

Other provisions

  1. 1

    The additive must be incorporated into compound feed in the form of a premixture. This compound feed must be placed on the market in a non-powdered form

  2. 2

    The following must be stated on the labelling of the additive and premixture:

    • The element (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. 3

    The following must be stated in the instructions for use of the compound feed:

    • “Protective measures to avoid exposure with cobalt by inhalation or by dermal route should be taken”
