An insight into the determination of the chemical composition of forages via NIRS is presented. Predictive models developed at the Agroscope Institute for Livestock Sciences ILS show the typical values: R2 > 0.96 for dry matter (DM), crude protein (CP), ADForg, NDForg, crude fibre (CF), cellulose, ash, fat, sugar and starch content in hay and grass, grass silage, green maize for silage and maize silage. The analysis of individual samples by NIRS is preferred to the analysis of a pooled sample by classical methods because NIRS shows the individual particularities of each sample.
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.
