Probably not natural skills, as resurrection carries over skills and such (I think?), which won't play well with the caste transformations. Learning rates, definitely - and other tricks that will narrow down their focus specialties.
[MILKABLE] higher means longer time before ready to be milked. Vanilla's milk template has [MATERIAL_REACTION_PRODUCT:CHEESE_MAT:LOCAL_CREATURE_MAT:CHEESE], so as long as yours doesn't have that line, it shouldn't be called in a cheese reaction. Unsure if there's any side effects to removing that token.
Also, didn't you reduced the pain receptors in the tissue templates? The latest save by Baffler still have the rather painful versions.
