Abstract

Grass harvested at early and late maturity stages was processed using a twin-screw press to produce a fibrous pulp fraction of which half was ensiled and the other half was pressed a second time before ensiling. For comparison, grass from the same field and maturity stage was mown and wilted before chopping and ensiling. The effects of single and double screw pressing compared with chopped grass on
density of the fresh material, fermentation weight loss, and fermentation pattern were investigated in labscale silo bags. All combinations of processing and time for regrowth resulted in well-preserved silages with variation in dry matter content, fermentation weight loss, and fermentation products.
