They might object to scenes of animal cruelty in individual cases, but there's no specific legislation like in the UK forcing them to cut scenes of staged animal carnage or horsefalls etc.
For instance, the censored VHS release of "Cannibal Holocaust" back in the 80's contained all scenes of animal cruelty, yet a lot of the fake gore was snipped.
It was first the release of a fully uncut VHS (followed by identically complete DVDs) much later in the very late 90's, which prompted their overly concerned institutions to take action beyond a simple entry on the "index of restricted movies" list, resulting in CH to be finally banned for good in Germany.
BTW: The censors have to ban each release of a movie individually over there. That's why the likes of CH, Antro, Tenebrae etc are popping up time and again...untill the next ban.
