Expected Behavior

Cap on growth/scaling of model and aging up

Actual Behavior

Model continues to scale up in size, no aging/advancing to next step in life cycle

Steps to Reproduce

Use spawn eggs to spawn a Jersey cow and bull, breed the two Jerseys and feed the calf oats from Pam's Harvestcraft. This seems to only be an issue with the Jersey cows, I tried it with the Holstein and Longhorn cows and the calves grew up normally while the Jersey calf remained gigantic.

Version of Minecraft, version of Animania, Single Player or Server

MC version 1.12.2, Animania (farm) version 1.0.0.23 (base 2.0.0.23, extra 1.0.0.23), single player
