[Animal welfare aspects of animal slaughter].

For many years animal welfare aspects of slaughtering were not discussed. But in the last ten years the research has much increased in this field. The new knowledges will be taken in account in national and european legislation. The question if ritual slaughtering without pre-slaughter stunning has to be allowed, was answered by the amendment of the Animal Welfare Act: This form of slaughtering is now only allowed in the context of constitutional guaranteed religious liberty.
