AAFCO 2014 vs 2015 framing

AAFCO 2014 and AAFCO 2015 share identical numerical values for all Dog and Cat nutrient profiles; the 2014 calcium maximum split (1.8% DM for Growth & Reproduction and All Life Stages vs 2.5% DM for Adult Maintenance, dogs) is the only structural change carried through this period, and all other nutrient values were identical between 2013 and 2014 as well. One documented formatting nuance: in the 2013 Pet Food Report the dog profiles appeared with the Calorie-basis table in Appendix A and the Dry-Matter-basis table in Appendix B (per the 2013/2015 profiles dataset metadata), whereas the 2014 Pet Food Report published the revised profiles together in a single Appendix A document containing both the DM-basis and calorie-basis tables. Because no numeric thresholds changed after the 2014 Ca split, manufacturers did not have to reformulate between 2013, 2014 and 2015 except to respect the new two-tier calcium maximum for large-breed growth products.
