Life-stage × jurisdiction vitamin matrix (dog & cat adult maintenance)
Fat-soluble vitamin minimum (and where given, maximum) levels for adult maintenance, compiled from the parsed cross-standard index and the NIAS 2024 standard. All values are expressed in IU/kg dry matter (IU/kg DM) so the three standards are directly comparable. Every numeric cell is a verbatim value of the named source files; the NIAS raw values are published per 100 g DM and are converted to IU/kg DM by ×10 (labelled "raw/100 g DM" in parentheses). Cells not present in a source are honest gaps, never interpolated.
Dog — adult maintenance (fat-soluble vitamins, IU/kg DM)
| Vitamin | AAFCO 2026 (US) | FEDIAF 2025 (EU) | NIAS 2024 (KR) |
|---|---|---|---|
| Vitamin A (min) | 5000 | 606 | 5000 (raw 500 /100 g DM) |
| Vitamin A (max) | 250000 | 40000 | 400000 (raw 40000 /100 g DM) |
| Vitamin D (min) | 500 | 55.2 | 500 (raw 50 /100 g DM) |
| Vitamin D (max) | 3000 | 320 | 3200 (raw 320 /100 g DM) |
| Vitamin E (min) | 50 | 3.6 | 36 (raw 3.6 /100 g DM) |
AAFCO sets no maximum for vitamin E; FEDIAF sets no vitamin E maximum for adult dog.
Cat — adult maintenance (fat-soluble vitamins, IU/kg DM)
| Vitamin | AAFCO 2026 (US) | FEDIAF 2025 (EU) | NIAS 2024 (KR) |
|---|---|---|---|
| Vitamin A (min) | 3332 | 333 | 3330 (raw 333 /100 g DM) |
| Vitamin A (max) | 333300 | 40000 | 400000 (raw 40000 /100 g DM) |
| Vitamin D (min) | 280 | 25.0 | 250 (raw 25 /100 g DM) |
| Vitamin D (max) | 30080 | 3000 | 30080 (raw 3008 /100 g DM) |
| Vitamin E (min) | 40 | 3.8 | 38 (raw 3.8 /100 g DM) |
Cats tolerate a far higher vitamin D maximum than dogs (AAFCO 30080, NIAS 30080 IU/kg DM) versus FEDIAF's 3000 IU/kg DM ceiling. AAFCO and NIAS set no vitamin E maximum.
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). Each quoted number is a verbatim value of the source JSON; NIAS raw per-100 g DM values are converted to IU/kg DM by ×10 and labelled.
- FEDIAF dog adult uses the 110 kcal/kg BW^0.67 column (inactive); FEDIAF cat adult
uses the 100 kcal/kg BW^0.67 column — matching the existing life_stage_nutrient_matrix AAFCO-vs-FEDIAF protein/fat/Ca/P extraction.
- Minerals (Fe, Zn, Cu, I, Se) and taurine are intentionally excluded here: AAFCO/FEDIAF
report trace minerals per kg DM while NIAS reports per 100 g DM, and selenium units differ (AAFCO mg/kg vs FEDIAF ㎍/kg), so a like-for-like comparison requires explicit unit reconciliation — recorded as an honest gap pending that reconciliation.
- Reproduce: re-read the named index keys / NIAS table cells; each quoted number is a
substring/value of the source JSON (raw values verified before the ×10 conversion).
