L-精氨酸 — additive cross-jurisdiction identity
Derived crosswalk of how one feed additive is named and authorised across three jurisdictions. No claim of regulatory equivalence is made — pairings are anchored on the substance identity, and the verdict states where the definitions actually diverge.

| 🇨🇳 CN | 公告2045 L-精氨酸 | L-精氨酸 is listed in 表一 饲料添加剂品种目录 (category 氨基酸、氨基酸盐及其类似物 for amino acids / 矿物元素及其络（螯）合物 for chelates / 维生素及类维生素 for vitamins), scope 养殖动物 (all livestock and poultry). | CN 公告2045 |
| 🇪🇺 EU | Feed Additives Register 2b17003 | L-Arginine / CAS No. 74-79-3 / Flavis No. 17.003 — functional category 2 b. Authorised in the EU feed additives register (first-hand-derived parse of the EU Food & Feed Information Portal register). Cross-jurisdiction note: this EU authorisation is quoted from the register and is not asserted to be equivalent to the CN 公告 2045 / FDA EAFUS entries (definitions, chemical form, or conditions of use may differ). | EU Food & Feed Information Portal feed-additives register; parsed dataset pdf-parsed/eu_feed_additives_2023_1813.json, e_number 2b17003 |
| 🇺🇸 AAFCO (US) | Ch.6 | No stand-alone AAFCO OP 2024 Ch.6 entry for this substance. AAFCO defines amino acids / vitamins only where a corresponding feed ingredient (often a fermentation product) is listed; where absent, the cell is an honest gap, not a claim of non-existence. | AAFCO OP 2024 Ch.6 — gap |
| 🇨🇦 CA | Feeds Regs 2024 (CFIT) | L-Arginine from fermentation process (or (S)-2-amino-5-guanidinopentanoic acid from fermentation process) — is the crystalline product containing a minimum of 80% (S)-2-amino-5-guanidinopentanoic acid, and having the CAS# 74-79-3. It is obtained from a fermentation process using a non-pathogenic strain of Corynebacterium glutamicum, which does not contain a novel trait. It shall contain not more than 18% moisture. The fermentation process shall be conducted in accordance with good manufacturing practices. It shall not contain other extraneous materials except in such amounts as may occur unavoidably during good manufacturing practices. If a carrier is used, it must be approved for use in livestock feeds, it shall be used at the approved rate, and the common name or names shall be indicated on the label. It shall be labelled with the following statement: "This ingredient is free of antimicrobial activity and is not a source of viable microbial cells." To address worker safety concerns, it shall be labelled with the following statement: "This ingredient may cause eye, skin and respiratory irritation and/or sensitization. Appropriate protective equipment must be worn during handling. / Cet ingrédient peut causer une irritation des yeux, de la peau et des voies respiratoires et/ou une sensibilisation. Un appareil de protection approprié doit être porter lors de la manutention." It shall be labelled with guarantees for minimum percent L-arginine, and maximum percent moisture. | Canadian Feed Ingredients Table (CFIT), inspection.canada.ca; SOR/2024-132; feed additive listed under Part 1 > Class 5. Nutritional ingredients > 5.1 Amino acids |
Crosswalk verdict
CN 公告2045 and EU 2019/12 both authorise L-arginine for all animal species. AAFCO OP 2024 Ch.6 has no stand-alone L-arginine entry. Verdict: CN↔EU equivalent; AAFCO gap.
