In 1981 an authorisation procedure for the sale of housing systems for farm animals was introduced in Switzerland. Authorisation shall only be granted if such systems provide proper living conditions for the animals. Requests for authorisations are handled at the two Centres for Proper Housing in Animal Production of the Swiss Federal Veterinary Office, which are situated in Tänikon and ollikofen.<br>Authorisations are only required for a limited number of species (cattle, pigs, goats, sheep, chicken turkeys, ducks, geese and rabbits) and only for. installations with which animals are in frequent contact. Decisions are made on the basis of experience with similar installations, knowledge from literature, visits to farms on which the housing systems are in use and, if necessary, practical tests.<br>The authorisation procedure has led to an improvement of the quality of housing systems for farm animals with regard to animal welfare. In addition, it has promoted research into applied ethology, into the development of methods for the scientific assessment of animal welfare and into new housing systems for farm animals.
Which stakeholders in the dairy sector have an influence on the productive life of dairy cows? Research results from FiBL and Agroscope suggest that broad-based cooperation is needed to create structures for a longer productive life.
Agriculture is aiming to reduce greenhouse gas and ammonia emissions. Agroscope showed that for dairy cattle housing, feed composition plays a role in these emissions as well as wind and temperature.

Tannin-containing feedstuffs like Acacia mearnsii and sainfoin (Onobrychis viciifolia) have a measurable impact in reducing methane emissions from dairy cows. However, since these feedstuffs in some cases lead to productivity losses, careful consideration must be given to their use.
