Per the 2014 Appendix A (Revised AAFCO Nutrient Profiles), the 2007 subcommittee review recommended that maximum calcium for large breed growth formulations be lowered to 1.8% DM (vs 2.5% previously); it did not recommend lowering the calcium maximum for small/moderate size breeds or adult dogs, which retained the 2.5% maximum. The 2014 Appendix A formalized this as a split-maximum footnote on the dog DM table, and the corresponding calorie-basis table carries footnote (d): a maximum of 4.5 g Ca/1000 kcal ME applicable to large breed growth formulations (≥70 lbs adult weight). The subcommittees behind the profiles were AAFCO's Canine and Feline Nutrition Expert Subcommittees (first convened 1990-1992 per Dzanis, J. Nutr. 1994). Phosphorus maximum stayed at 1.6% DM for both life stages, and all other nutrient values were unchanged from AAFCO 2013.\n","sources":["AAFCO wp-content/uploads PDF — AAFCO 2014 CNES origin story (retrieved 2026-07-21)"],"source":{"authority":"AAFCO wp-content/uploads PDF","title":"AAFCO 2014 CNES origin story","url":"https://www.aafco.org/","retrieved":"2026-07-21","ref":"","doc_type":"official source","source_document":"AAFCO Model Pet Food Regulations","verification_file":""},"source_document":"AAFCO Model Pet Food Regulations","source_file":"","trust":{"authority_tier":"T1","fidelity":"verbatim","license":null,"display_grade":"A"},"tokens_estimated":132,"generated_at":"2026-07-16","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.","structured_data":{"note":"The nutrient values in this topic are also available as structured data — faster and exact, no text parsing needed.","compare":"/api/v1/cross_compare?standards=AAFCO,FEDIAF,KFDA&species=dog&lifestage=adult&nutrient=protein&basis=DM","coverage":"Standards: AAFCO (year>=2014), FEDIAF (year>=2025), EU PARNUT (year>=2020), KFDA/NIAS Korea (year>=2024). species: dog|cat. lifestage: adult|GR (growth/puppy/kitten map to growth-reproduction). basis: DM|cal.","single":"/api/v1/nutrient?standard=AAFCO&year=2024&species=dog&lifestage=adult&nutrient=protein&basis=DM","batch":"/api/v1/batch_nutrient?standard=AAFCO&year=2024&species=dog&lifestage=adult&nutrients=protein,fat,calcium,phosphorus&basis=DM"}}
