The majority of Swiss farms take part in the RAUS and BTS voluntary programmes for animal welfare. BTS: The BTS programme, which aims to ensure particularly animal-friendly housing systems, serves to further enhance animal welfare standards, as its requirements go above and beyond those contained in the legislation in force. 58% of Swiss livestock benefit from the BTS programme (as at 2019). RAUS: Just like us, animals also like being outdoors. That’s why the RAUS programme stipulates that pigs and cows have access to a paved outdoor area. This means that pigs, for example, also have a larger overall area to live in. 86.4% of Swiss farms take part in this voluntary programme (as at 2019).
