Life-stage × jurisdiction growth/reproduction matrix (dog & cat)
Minimum protein / fat / calcium / phosphorus for growth & reproduction, compiled from the parsed cross-standard index and the NIAS 2024 standard. Unlike the vitamin/mineral comparison, all three standards here express these as g per 100 g DM (AAFCO % DM = g/100 g; FEDIAF per 100 g DM; NIAS per 100 g DM), so the numbers are directly comparable with no unit conversion. Cells not present in a source are honest gaps, never interpolated.
Dog — growth / reproduction (g/100 g DM = % DM)
| Nutrient | AAFCO 2026 | FEDIAF 2025 (early / late growth) | NIAS 2024 (initial / late growth) |
|---|---|---|---|
| Crude protein (min) | 22.5 | 25.0 / 20.0 | 22.5 / 20.0 |
| Crude fat (min) | 8.5 | 8.5 / 8.5 | — (not listed) |
| Calcium (min–max) | 1.2 – 1.8 | 1.0 / 1.6 (early) ; 0.8 / 1.8 (late) | 1.00 / 2.5* (initial) ; 0.80 / 2.5* (late) |
| Phosphorus (min) | 1.0 | 0.9 (early) ; 0.7 (late) | 0.90 (initial) ; 0.70 (late) |
\* NIAS calcium maximum 2.5 g/100 g DM (a 1.8 g/100 g DM variant is noted in 표 2-17a for the restricted/large-breed condition).
Cat — growth / reproduction (g/100 g DM = % DM)
| Nutrient | AAFCO 2026 | FEDIAF 2025 (growth / reproduction) | NIAS 2024 (growth / reproduction) |
|---|---|---|---|
| Crude protein (min) | 30.0 | 28.0 / 28.0 | 28.0 / 30.0 |
| Crude fat (min) | 9.0 | 9.0 / 9.0 | — (not listed) |
| Calcium (min) | 1.0 | 1.0 / 1.0 | 1.0 / 1.0 |
| Phosphorus (min) | 0.8 | 0.84 / 0.84 | 0.8 / 0.8 |
Method & honest-gap notes
- Source of truth:
pdf-parsed/cross_standard_nutrient_index.json—aafco_us_2026
(dog_growth_reproduction, cat_growth_reproduction) and fediaf_2025_summary.lifestages (dog_early_growth, dog_late_growth, cat_growth, cat_reproduction); plus pdf-parsed/kr-2026/korea_nias_nutrient_standard.json tables 표 2-17a (dog growth) and 표 2-17e (cat growth/reproduction). Every numeric cell is a verbatim value of the source JSON.
- Direct comparability: protein/fat/Ca/P are all on a per-100 g DM basis across the three
standards, so no ×10 or unit harmonization is needed here (contrast with the mineral topic).
- Fat gaps: NIAS 표 2-17a / 표 2-17e do not list a crude-fat minimum for growth stages →
honest gap; AAFCO and FEDIAF both set 8.5 (dog) / 9.0 (cat).
- FEDIAF stage split: dog growth is split into early (<14 wk) and late (≥14 wk); cat growth
and reproduction share the same values in the source.
- Reproduce: re-read the named index keys / NIAS table cells; each quoted number is a
substring/value of the source JSON.
