Life-stage × jurisdiction mineral matrix (dog & cat adult maintenance)
Trace-mineral minimum (and where given, maximum) levels for adult maintenance, compiled from the parsed cross-standard index and the NIAS 2024 standard. Each standard publishes minerals in its own native unit, so two tables are given: (A) source-stated native units (every number verbatim from the source file) and (B) a harmonized view with NIAS converted from per-100 g DM to per-kg DM (×10) and selenium unified to ㎍/kg DM. Cells not present in a source are honest gaps, never interpolated.
(A) Dog — adult maintenance, native units as stated
| Mineral | AAFCO 2026 (mg/kg DM) | FEDIAF 2025 (mg/kg DM; Se ㎍/kg) | NIAS 2024 (mg/100 g DM; Se ㎍/100 g) |
|---|---|---|---|
| Iron (min) | 40 | 3.6 | 3.60 |
| Zinc (min) | 80 | 7.2 | 7.20 |
| Copper (min) | 7.3 | 0.72 (max 2.8) | 0.72 |
| Iodine (min–max) | 1.0 – 11.0 | 0.11 | 0.10 – 1.10 |
| Manganese (min) | 5.0 | 0.58 | 0.50 |
| Selenium (min) | 0.35 mg/kg (max 2.0) | 18 ㎍/kg | 18 – 200 ㎍/100 g |
(A) Cat — adult maintenance, native units as stated
| Mineral | AAFCO 2026 (mg/kg DM) | FEDIAF 2025 (mg/kg DM; Se ㎍/kg) | NIAS 2024 (mg/100 g DM; Se ㎍/100 g) |
|---|---|---|---|
| Iron (min) | 80.0 | 8.0 | 8.0 |
| Zinc (min) | 75.2 | 7.5 | 7.5 |
| Copper (min) | 5.0 (extruded/canned) | 0.5 (max 2.8) | — (not in 표 2-17f) |
| Iodine (min–max) | 0.6 – 9.0 | 0.13 | 0.06 – 1.10 |
| Manganese (min) | 7.6 | 0.5 | 0.50 |
| Selenium (min) | 0.3 mg/kg | 21 ㎍/kg | 21 ㎍/100 g |
(B) Harmonized view (all mg/kg DM except selenium ㎍/kg DM)
NIAS per-100 g DM values are multiplied by 10 to reach per-kg DM so the three standards sit on one basis. Selenium is unified to ㎍/kg DM (AAFCO 0.35 mg/kg = 350 ㎍/kg; NIAS 18 ㎍/100 g = 180 ㎍/kg).
| Mineral | AAFCO | FEDIAF | NIAS (×10) |
|---|---|---|---|
| Dog Fe (min) | 40 | 3.6 | 36 |
| Dog Zn (min) | 80 | 7.2 | 72 |
| Dog Cu (min) | 7.3 | 0.72 | 7.2 |
| Dog I (min–max) | 1.0 – 11.0 | 0.11 | 1.0 – 11.0 |
| Dog Mn (min) | 5.0 | 0.58 | 5.0 |
| Dog Se (min–max) | 350 – 2000 ㎍/kg | 18 ㎍/kg | 180 – 2000 ㎍/kg |
| Cat Fe (min) | 80.0 | 8.0 | 80.0 |
| Cat Zn (min) | 75.2 | 7.5 | 75.0 |
| Cat Cu (min) | 5.0 | 0.5 | — |
| Cat I (min–max) | 0.6 – 9.0 | 0.13 | 0.6 – 11.0 |
| Cat Mn (min) | 7.6 | 0.5 | 5.0 |
| Cat Se (min) | 300 ㎍/kg | 21 ㎍/kg | 210 ㎍/kg |
(AAFCO cat selenium 0.3 mg/kg = 300 ㎍/kg; NIAS cat 21 ㎍/100 g = 210 ㎍/kg.)
Method & honest-gap notes
- Source of truth:
pdf-parsed/cross_standard_nutrient_index.json—aafco_us_2026
(dog/cat adult maintenance) and fediaf_2025_summary.lifestages (dog adult nutrients_110kcal, cat adult nutrients_100kcal); plus pdf-parsed/kr-2026/korea_nias_nutrient_standard.json tables 표 2-17b (dog 성견) and 표 2-17f (cat 성묘). Every number in table (A) is a verbatim value of the source JSON; table (B) multiplies only the NIAS raw per-100 g DM figures by 10.
- FEDIAF magnitude flag (do not misread): FEDIAF's Fe/Zn/Cu/I/Mn minima (dog 3.6 / 7.2 /
0.72 / 0.11 / 0.58 mg/kg) are roughly an order of magnitude below AAFCO and NIAS-per-kg (dog 40 / 80 / 7.3 / 1.0 / 5.0). This gap most likely reflects a different reference basis in the FEDIAF source (or a parse artifact) rather than FEDIAF genuinely permitting ~10× less dietary iron — it is flagged here for verification and must not be quoted as a real regulatory divergence without confirming the FEDIAF basis. Selenium units also differ (AAFCO mg/kg vs FEDIAF/NIAS ㎍/kg) and are unified only in table (B).
- Gaps: NIAS cat copper is absent from 표 2-17f (honest gap); AAFCO sets no copper maximum
for adult dog/cat in this source; FEDIAF sets no iodine/selenium maximum for adult stages.
- Reproduce: re-read the named index keys / NIAS table cells; each quoted number is a
substring/value of the source JSON before any ×10 harmonization.
