Grass silage represents the greater part of winter feed rations. It is therefore important to make the highest quality silage possible. Molasses as a silage additive provides a source of readily fermentable sugar to promote the ensiling process.
When ensiling grass in unfavourable weather, using molasses improves the quality of the resultant silage dramatically. The effectiveness of molasses as a silage additive is related to the type of sward being ensiled. Old permanent swards produce the bulk of Ireland’s silage and these are more difficult to ensile than newly established swards.
