{"topic_id":"AAFCO_2014_Ca_P_split","category":"aafco","context":"AAFCO 2014 is the transitional year that split the single 2.5% Ca max (2013) into two tiers: 1.8% max for Growth & Reproduction, 2.5% max for Adult Maintenance. This change was driven by 2007 CNES (Center for Nutrition and Exercise Sciences) concerns about large-breed puppy skeletal development from excess calcium. Phosphorus max simultaneously tightened to 1.6% for both life stages. All other nutrient values (protein, fat, vitamins, trace minerals) remained unchanged from AAFCO 2013. The 2015 Official Publication retained the same numbers with revised explanatory framing. AAFCO 2024 still carries these values forward.","sources":["generated from .md only"],"tokens_estimated":120,"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."}
