• Background

  Approximately two-thirds of greenhouse gas emissions in Norwegian agriculture come from ruminants, and the majority of the emissions are methane from ruminant digestion. Roughage accounts for a large proportion of the animals' feed ration. It is also a national goal to increase the proportion of roughage and Norwegian-produced feed in the ration for ruminants. This means that identifying the properties of low-emission roughage will have a major impact on greenhouse gas emissions from agriculture.

  Grass forage, which is the dominant roughage, is produced in many different ways, resulting in great variation in the properties of the roughage (e.g. botanical composition, digestibility and fermentation quality). These are properties that affect methane emissions from the animals. At the same time, these must be properties that can be utilised to reduce methane emissions under both practical and economic conditions.

• Objectives

  The main goal is to develop strategies in surf feed production that reduce methane emissions from ruminant digestion.
