The percentage of taurine must be guaranteed. It is used as a nutritional supplement in cat foods, dog foods, and fish foods. Taurine may also be added to the feed of growing chickens; when added to complete chicken feed, the total taurine content shall not exceed 0.054% of the feed (21 CFR 573.980). (Proposed 2017 rev. 1, Adopted 2019 rev. 1)  _(src: AAFCO OP 2024 Ch.6, code 6.12)_\n- **🇪🇺 EU**: no entry in the Reg (EU) 68/2013 Feed Catalogue — see note (additive framework / category-based PAP). _(src: EU Reg 68/2013 Annex)_\n- **🇨🇳 CN — 公告1773 `牛磺酸`**: not listed as a standalone entry in 公告1773 饲料原料目录; framework: 公告1773 is a positive list, the ingredient name must match the directory. _(src: 公告1773)_\n\n## Crosswalk verdict\n\nTaurine is an additive, not a feed-ingredient-catalogue entry. AAFCO lists it in Ch.6 (as a feed ingredient/additive); CN lists it in the 添加剂目录 (2045). The EU Reg 68/2013 catalogue has NO taurine entry — in the EU it is authorised as a feed additive (Reg 1831/2003). So there is no EU feed-catalogue equivalent to cite; only the additive framework applies.\n\n## Multilingual names (official where free)\n\n- EN (AAFCO/EU): see per-jurisdiction entry above\n- ZH (CN): 牛磺酸 (extraction pending)\n- ES / FR / DE (EUR-Lex 68/2013 official 24-language versions): pending — collection via EUR-Lex multilingual fetch is the O2 prerequisite\n- JA (FAMIC 飼料の公定規格 別表): pending — no corresponding entry in the FAMIC feed catalogue\n- KO (사료 등의 기준 및 규격 별표 5, law.go.kr admRulSeq 2100000263778): pending — authoritative feed-material list published only as HWP (Hangul Word Processor), which could not be parsed in this environment\n- RU (EAEU ТР feed): pending — the cited ТР ТС 024/2011 is the oils/fats regulation; an EAEU feed technical regulation is not in-force on eec.eaeunion.org and national texts (adilet.zan.kz, souzkombikorm.ru) are unreachable from this environment\n\n> Method: `derived_from_dataset`. Every quoted name/definition is from the first-hand source cited per cell. Equivalence is a derived editorial judgement anchored on Latin name + process; where jurisdictions use different regulatory units (named meal vs category-based PAP) the verdict is `regulatory_divergence` / `no_confirmed_equivalent` rather than 'same'.\n","sources":["ingredient-crosswalk — Taurine — cross-standard identity (retrieved 2026-08-06)"],"source":{"authority":"ingredient-crosswalk","title":"Taurine — cross-standard identity","url":"https://www.aafco.org/","retrieved":"2026-08-06","ref":"公告第1773号","doc_type":"official PDF","source_document":"AAFCO OP 2024 Ch.6; EU Reg 68/2013 Annex; CN Ann.1773 饲料原料目录","verification_file":"pdf-parsed/aafco_ch6.txt ; pdf-parsed/eu_feed_catalogue_materials_20260714.json ; pdf-raw/cn-law/cn_feed_ingredient_dir_ann1773_bjhr.txt"},"source_document":"AAFCO OP 2024 Ch.6; EU Reg 68/2013 Annex; CN Ann.1773 饲料原料目录","source_file":"pdf-parsed/aafco_ch6.txt ; pdf-parsed/eu_feed_catalogue_materials_20260714.json ; pdf-raw/cn-law/cn_feed_ingredient_dir_ann1773_bjhr.txt","trust":{"authority_tier":"T1","fidelity":"verbatim","license":null,"display_grade":"A"},"tokens_estimated":600,"generated_at":null,"tip":"Use /api/v1/topics to discover more topics. /api/v1/nutrient for precise single-point queries. /api/v1/cross_compare for 2-3 standard comparisons."}
