The ensilability and the silage quality of six different lucerne and five different cocksfoot varieties was tested. The plants were cultivated in the variety testing program of Agroscope FAL Reckenholz. The forage of the first and third cut was used. The forage was pre-wilted to 25 % DM in the first and 30 % in the third cut, short chopped and ensiled in laboratory silos.As to lucerne the fermentabillity coefficients varied between 35 and 39 for the first and between 42 and 54 for the third cut. For cocksfoot these coefficients amounted from 31 to 38 for the first and from 40 to 45 for the third cut.The silages with the different lucerne varieties contained practical no butyric acid, they had high DLG points and therefore the silage quality was good. Butyric acid was found in all silages with the different cocksfoot varieties. The values were higher for the forage of the first in comparison to the third cut. This is a result of the different dry matter contents. The quality of these silages was medium to bad. The results show, that despite of similar fermentability coefficients between lucerne and cocksfoot, there existed differences in the silage quality. The differences between the two plants were bigger than within the different varieties of the same species. Especially with cocksfoot, the pre-wilting degree influenced the silage quality.
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.
