丙酸锌 — additive cross-jurisdiction identity

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

Substance anchor: 丙酸锌 (Zinc propionate)
Verdict: closest_with_differences

Per-jurisdiction entry

🇨🇳 CN — 公告2045 丙酸锌: 丙酸锌 is listed in 表一饲料添加剂品种目录 (category 矿物元素及其络（螯）合物); scope 猪、牛和家禽. _(src: CN 公告2045)_
🇪🇺 EU — Feed Additives Register: No current EU authorisation entry for this substance was found in the EU feed additives register (EU Food & Feed Information Portal; parsed dataset pdf-parsed/eu_feed_additives_2023_1813.json). Zinc propionate has no entry in the EU feed additives register (only calcium / sodium / ammonium propionate are listed). Do not fabricate an EU entry. _(src: EU Food & Feed Information Portal feed-additives register; parsed dataset pdf-parsed/eu_feed_additives_2023_1813.json — no matching authorisation; honest gap)_
🇺🇸 FDA (US) — EAFUS: No corresponding FDA EAFUS entry found for Zinc propionate (search of FDA EAFUS for 'ZINC PROPIONATE' returned no 21 CFR listing for this substance); no US entry quoted — not fabricated. _(src: FDA EAFUS — gap)_
🇺🇸 AAFCO (US) — Ch.6 57.160 Zinc Propionate: is the product resulting from reaction of a zinc salt with propionic acid. _(src: AAFCO OP 2024 Ch.6, code 57.160)_

🇨🇦 CA — honest gap: not listed in CFIT as a feed additive. _(src: Canadian Feed Ingredients Table (CFIT), inspection.canada.ca; SOR/2024-132)_

Crosswalk verdict

CN 公告2045 lists 丙酸锌 (scope 猪、牛和家禽). FDA EAFUS contains no corresponding entry for Zinc propionate (search for 'ZINC PROPIONATE' returned no 21 CFR listing); recorded as an honest no_confirmed_equivalent — not fabricated. AAFCO OP 2024 Ch.6 defines Zinc Propionate (code 57.160). Verdict: CN↔US diverge in chemical form or regulatory framing; the pairing is the closest available US analogue, not a confirmed regulatory equivalence (EU noted as honest gap).

Species & use scope (适用范围)

Cross-jurisdiction species / use-scope dimension surfaced from each jurisdiction's retrieved source. CN 适用范围 is quoted verbatim from the 公告2045 饲料添加剂品种目录; EU target-species and FDA use-class reflect only what is already present in the topic's own cells (no new source fetches).

🇨🇳 CN (公告2045 适用范围): 猪、牛和家禽 _(src: 农业部公告第2045号饲料添加剂品种目录, 适用范围)_
🇪🇺 EU (target species): honest gap — target-species / conditions of use not present in the currently retrieved EU source (conditions_of_use deferred). _(src: EU Feed Additives Register — gap)_
🇺🇸 FDA (EAFUS use class): honest gap — use class not present in the currently retrieved source (no FDA EAFUS entry found). _(src: FDA EAFUS — gap)_
