AAFCO 2014 Ca P split

AAFCO 2014 is the transitional year that split the single 2.5% Ca max (2013) into two tiers: 1.8% max for Growth & Reproduction (and All Life Stages) products, 2.5% max for Adult Maintenance products only. The change was driven by expert-subcommittee concerns about large-breed puppy skeletal development from excess calcium: the 2014 Appendix A notes the subcommittee recommendation that maximum calcium for large breed growth formulations be lowered to 1.8% DM (vs 2.5% previously), and adds that no lowering was recommended for small/moderate size breeds or adult dogs. The split is formalized as a footnote on the dog food DM table: "The maximum of 1.8% is applicable to products formulated to meet the Growth and Reproduction Nutrient Profile and products formulated for All Life Stages. The maximum of 2.5% is applicable only to products formulated to meet the Adult Maintenance Nutrient Profile." Phosphorus maximum remained 1.6% DM for both life stages, and all other nutrient values (protein, fat, amino acids, other minerals, vitamins) were identical between AAFCO 2013 and 2014. The values are carried forward in subsequent AAFCO Official Publications (per the US nutrient profiles dataset, the 2024 edition is a carry-over of the 2014/2016 revisions).
