Could you ask the developers what the real effects of these items are for Chocobo raising? There is wildly different information on the Internet about what stats it raises such as Strength, Endurance, Discernment, and Receptivity. The JP wiki at wiki.ffo.jp says that Carrot Paste is random and any of the values can go up or down, while the English wiki at Wikia says that Carrot Paste raises everything but has no impact on discernment.
