About 2/3 of greenhouse gas (GHG) emissions in Norwegian agriculture come from ruminants, and the main part of the emissions is methane from the ruminants' digestion. Forage makes up a large proportion of the animals' feed ration. It is also a national goal to increase the proportion of forage and the proportion of domestic produced feed in the ruminant's diet. Thus, it will have a major impact on GHG emissions from agriculture if it is possible to uncover the properties of a low-emission forage.
Grass silage, which is the dominant forage source, is produced in many ways, which results in great variation in the properties of the silage. It can be botanical composition, digestibility, and fermentation quality. These are properties that may affect enteric methane emissions from animals. At the same time, these must be properties that can be used to reduce methane emissions in practice and be economic viable
NIBIO's role in the project is:
- to test the effect of gassland type, cut, degree of wilting and fermentation pattern of silage on enteric methane production. This is done by making silage from a field experiment and measuring methane production from the silage in bottles with added rumen fluid from dairy cows
- to contribute with planning and interpretation of results from a feeding experiment with dairy cows where different grass silage types are tested with regard to the production of milk and enteric methane
- to make an economic and environmental analysis of various measures in the production and utilization of silage to reduce enteric methane emissions from milk production
