牛磺酸 — 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.

Per-jurisdiction entry
- 🇨🇳 CN — 公告2045
牛磺酸: 牛磺酸 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). _(src: CN 公告2045)_ - 🇪🇺 EU — Reg 1831/2003
(EU) 2018/249: Commission Implementing Regulation (EU) 2018/249 of 15 February 2018 concerning the authorisation of taurine, beta-alanine, L-alanine, L-arginine, L-aspartic acid, L-histidine, D,L-isoleucine, L-leucine, L-phenylalanine, L-proline, D,L-serine, L-tyrosine, L-methionine, L-valine, L-cysteine, glycine, monosodium glutamate and L-glutamic acid as feed additives for all animal species _(src: EU (EU) 2018/249)_ - 🇺🇸 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. _(src: AAFCO OP 2024 Ch.6 — gap)_
Crosswalk verdict
CN 公告2045 lists 牛磺酸 (taurine) for 养殖动物. EU 2018/249 authorises taurine (with a group of amino acids) as a feed additive for all animal species. AAFCO OP 2024 Ch.6 has no stand-alone taurine feed-ingredient entry. Verdict: CN↔EU equivalent; AAFCO gap.
