The degree to which the housing system with fully slatted floor (without outdoor area) or the littered multy-surface system with restricted outdoor area may have an influence on that fat free lean (FFL) of fattening pigs was examined on the basis of data from 95 farms. In the system with fully slatted floor, the FFL of carcass and belly was significantly higher than in the littered multy-surface system with restricted outdoor area. During the second fattening period (winter-spring 2000/2001), the FFL values were higher than during the first fattening period (summer-autumn 2000). When analysing the interaction between housing system and fattening period, the FFL values of pigs kept in the littered multi-surface system with restricted outdoor area were significantly lower only in the first fattening period. Therefore no system-immanent effect can be assigned to either of the two housing systems. A tendency was observed for higher FFA values in pigs with complete feeding compared with pigs with whey feeding system.
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.
