Being Italian, I find queer that I never heard anything even similar to the two cited sayings:
>I will talk about it with my horse (Italian)
>I don’t give a cabbage (Italy)
EDIT: Ok, correction, the second one, as "I don't care a cabbage" is fine.
>I will talk about it with my horse (Italian)
>I don’t give a cabbage (Italy)

Never heard the one about the horse either.
In Tuscany, it would be the "(but) I care (or don't care) a (beautiful) saw"->(ma) (non) m'importa una (bella) sega)
