AnimalFeedAdditives.net is an independent reference on feed additives as Regulation (EC) No 1831/2003 and the US system define them, covering the five EU categories, their substances, species programmes and regulation, with every value tied to the body that issued it. It is written for professionals who need to know what an additive is, choose between options, comply with the rules and source it.
The additives themselves are classified by EU category and US route on types of feed additives. The site sells no additive and no listing, it carries no veterinary or feeding advice, and it names the primary source and date of every regulatory value.
Every statement is compiled from the named primary sources and dated; the sources and checks are described in the methodology.
What Is AnimalFeedAdditives.net?#
AnimalFeedAdditives.net is a reference publication on substances, micro-organisms and preparations added to feed or water, written for the people who choose, formulate, buy and register them. It follows the legal definition in Regulation (EC) No 1831/2003, Article 2(2)(a): "substances, micro-organisms or preparations, other than feed material and premixtures, which are intentionally added to feed or water in order to perform, in particular, one or more of the functions mentioned in Article 5(3)". Its readers want to know, choose, comply and source.
It is not a regulator and not a seller. Authorisations stay with the European Commission, the Food and Drug Administration and the other issuing bodies, and the site reports their decisions with the act and the date.
Who is the reference written for?#
The reference is written for five professional reader groups, listed below.
- Nutritionists
- Feed mill and premix managers
- Integrators
- Pet food and aquafeed manufacturers
- Distributors, buyers and regulatory staff
What Does the Feed Additive Reference Cover?#
The feed additive reference covers the five EU categories and their 26 functional groups, the substances authorised or marketed within them, species programmes, the production problems additives address, regulation in the EU, US and other markets, and sourcing. The 26 groups stand since Commission Regulation (EU) 2019/962. The US side has four routes: food additive, GRAS, new animal drug in feed and AAFCO-defined ingredient.
| # | Section | What it holds | Example value shown |
|---|---|---|---|
| 1 | Feed additive categories | five EU categories, 26 functional groups, US routes | 5 categories, Art. 6(1) of Regulation (EC) No 1831/2003 |
| 2 | Feed additive substances | one page per additive: identity, function, EU and US status | identification number and printed expiry |
| 3 | Feed premixes | premixtures as carriers of micro-ingredients | premixtures are not feed additives, Art. 2(2)(e) |
| 4 | Feed additives by species | programmes for poultry, pigs, cattle, dairy, sheep and goats, horses, aquaculture, pet food | doses per kg complete feed (12 % moisture) |
| 5 | Production problems and the feed additives that address them | what additives can and cannot claim | no "prevent, treat or cure" |
| 6 | Feed additive regulation worldwide | EU, US, UK, China, India, Brazil | 10-year EU authorisation; GB no end date |
| 7 | Feed additives compared | side-by-side choices | EU and US status side by side |
| 8 | Feed additive manufacturers and suppliers | how to qualify a supplier | no ranking of named companies |
| 9 | Feed additive news | dated authorisations, renewals and withdrawals | FDA GRAS proposal of 2026-08-11 |
EU and US status always sit side by side, and a US approval never implies EU status or the reverse.
Where does the reference stop?#
The reference stops where a topic is no longer a feed additive: feed materials and compound feed as such, raw mineral commodities, feed-mill equipment, breeds, housing and diseases as topics are not covered. The exclusions are:
- No feed materials or compound feed as such
- No veterinary drugs outside feed
- No human supplements or food additives
- No consumer pet-owner or backyard keeping advice
- No antibiotic dosing: antibiotics appear only as approval status, history and alternatives by jurisdiction
Treatment of livestock drinking-water systems and crop-protection spray adjuvants are not covered here.
Does the reference give veterinary or feeding advice?#
No: the reference gives no veterinary advice, no treatment or dosing advice for sick animals and no feeding recommendation for a specific herd or flock. An EU feed additive never "prevents, treats or cures" disease under Article 13(3) of Regulation (EC) No 1831/2003, so pages state what the authorisation states. Each dose is shown with its basis, never as a recommendation.
Decisions on animal health belong to a veterinarian, formulations to the responsible nutritionist, and legal questions to the competent authority.
Which Primary Sources Does AnimalFeedAdditives.net Use?#
AnimalFeedAdditives.net takes its values from ten primary sources: EUR-Lex and the Publications Office, the EU Register of Feed Additives, EFSA FEEDAP opinions, the eCFR, FDA's Center for Veterinary Medicine, AAFCO, the UK FSA register, PubChem, ECHA and peer-reviewed journals, each named in the sentence that uses it. The EU Register has been online on the Food and Feed Information Portal since 2023-04-05, and register counts are rows with an access date, not substances.
| Source | Issuing body | Values it supplies | How the site cites it |
|---|---|---|---|
| EUR-Lex and the Publications Office | EU | regulations, implementing regulations, directives | instrument, article and date, for example "Regulation (EC) No 1831/2003, Art. 2(2)(a)" |
| EU Register of Feed Additives | European Commission (Food and Feed Information Portal) | identification numbers, holders, register notes | entry with access date, "accessed 3 November 2026" |
| EFSA FEEDAP opinions | EFSA | safety and efficacy conclusions | EFSA Journal year and doi |
| eCFR | US Office of the Federal Register | 21 CFR 558, 573, 582 and 584 sections | section number and eCFR date |
| FDA CVM | FDA | guidance, enforcement policy, GRAS notices | guidance number and Federal Register date, for example GFI #293 of 2024-10-24 |
| AAFCO | AAFCO | ingredient definitions in the Official Publication | definition with edition; never "approved" |
| UK FSA register | Food Standards Agency | GB authorisations | register entry; no end date since 2025-04-01 |
| PubChem | NIH | CAS numbers, formulas, structures | compound record |
| ECHA | European Chemicals Agency | EC numbers, CLP classification | Annex VI index or notified classification |
| Peer-reviewed journals | publishers | effect sizes, meta-analyses | authors, year, journal and doi in the sentence |
Trade press, market reports and manufacturer data appear only where no primary source gives the value, and are then named as such. Market size appears only as a range of named publishers with the year.
How are values checked, dated and stated?#
Every regulatory value carries its instrument, article and date, every dose carries its basis, and every status carries the wording of the act, so a reader sees which version a number comes from. Values are checked against the issuing body, and a newer act replaces the older value; each step is described under methodology and fact-checking. Evidence is ranked: an EU authorisation with an EFSA efficacy conclusion first, then a peer-reviewed meta-analysis, then a single trial, then a supplier claim.
| Value type | How it is written | Pattern |
|---|---|---|
| EU authorisation | instrument and printed expiry; 10 years, renewable | "Implementing Regulation (EU) ..., expiry " |
| Passed expiry, renewal application on the register | register wording verbatim | "printed expiry ; the EU Register records a renewal application and still lists the entry pending the Commission decision (Article 14 of Regulation (EC) No 1831/2003)" |
| Passed expiry, no register note | no verb about the entry's fate | "printed expiry ; renewal decision not found" |
| Holder | named only where the act names one | zootechnical additives, coccidiostats and histomonostats, GMO additives |
| EU dose | per kg complete feed (12 % moisture), Art. 2(2)(f) | mg, IU, FTU, CFU or U per kg |
| Legal minimum vs maximum | minimum for enzymes and micro-organisms, never an optimum; maximum for vitamins, trace elements and preservatives | "legal minimum", "legal maximum" |
| Dose basis | EU legal limit, US approved level under 21 CFR 558, NRC requirement, or one named trial or manufacturer | basis in brackets |
| Effect size | species, dose, conditions and study | one trial is never a general effect |
| Hazard line | CLP Annex VI, else ECHA notified classification, else the supplier SDS | "see the supplier SDS" |
| Date of application | applies-from date, not adoption month | Implementing Regulation (EU) 2026/1115 applies from 2026-12-16 |
| Proposed rule | "proposed", with publication and comment dates | see below |
Proposed and final rules stay apart. FDA's mandatory GRAS notification is a proposed rule published on 2026-08-11, with comments closing on 2026-12-09, and is never written as final. In Great Britain, authorisations carry no period of validity or end date from 2025-04-01 (SI 2025/361, reg. 23(3)), so GB status is never read from an EU expiry. AAFCO no longer "approves" ingredients since its memorandum with FDA expired on 2024-10-01, and FDA's enforcement policy for AAFCO-defined ingredients is GFI #293 of 2024-10-24.
How Does AnimalFeedAdditives.net Earn Income and Stay Independent?#
AnimalFeedAdditives.net earns income from two reader requests, a quote request passed to independent suppliers and a question passed to independent regulatory or formulation experts, and it sells no product, no ranking and no listing. No company is ranked or recommended; companies appear only as register holders, trade-name holders or market facts.
Both requests start from the feed additive quote and expert match tools. We state the rule beside every form: "We pass requests on to independent suppliers and experts; nobody pays to be named on this site (see the editorial policy)."
The site uses no analytics or advertising vendors; what the forms collect is described in the privacy policy.
