The Regulation

Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on additives for use in animal nutrition establish a Community procedure for authorising feed additives and lays down rules for their placing on the market, labelling and use.

The regulation applies to all feed additives and premixtures. It does not apply to:

General Aspects

Only additives that have been through an authorisation procedure may be placed on the market and used. Authorisations are granted for use in feed intended for specific animal species or categories, and for specific conditions of use.

Additives may be classified into the following categories:

  • Technological additives (e.g. preservatives, antioxidants, emulsifiers, stabilising agents, acidity regulators, silage additives)
  • Sensory additives (e.g. flavourings, colorants)
  • Nutritional additives (e.g. vitamins, minerals, aminoacids, trace elements)
  • Zootechnical additives (e.g. digestibility enhancers, gut flora stabilizers)
  • Coccidiostats and histomonostats

These categories are themselves divided into functional groups according to the additives' main functions.

Antibiotics, other than coccidiostats or histomonostats, are not feed additives.


Additives must be labelled in a conspicuous, clearly, legible and indelible manner. The label shall include the following information:

  • the specific name given to the additives upon authorisation, the functional group and their identification number
  • the name and address or registered place of the person responsible for these particulars
  • the net weight or net volume of the additives
  • where appropriate the approval number of the establishment manufacturing orm placing the additive on the market
  • directions for use and any safety recommendations regarding use and, where applicable
  • the specific requirements mentioned in the authorisation
  • the batch reference number and date of manufacture.

The Regulation also establishes requirements for the labelling of premixtures of feed additives.
