According to Feedipedia.org and L Pernia, Silage is a good method for storing wet brewers grain for a longer period, particularly since ensiling does not alter their nutritive value (Geron et al., 2008).

  • Fill the silo at once.
  • Provide flow to the juice.
  • Do not use too broad and tall silos.
  • Quickly cool and press before ensiling (Boessinger et al., 2005)
  • Can be ensiled without additive or other raw material provided they are put into the silo as soon as possible.
  • Protect from rain and cover the grains hermetically (plastic film).
  • Pack uniformly but not excessively so as to eliminate air pockets between the job and the tarp.
  • The silo should have proper drainage to collect runoff
  • Brewer’s grains silage is ready within 3 weeks and can be used over 6 months, and longer if a silage additive is used (Boessinger et al., 2005).
  • Storage time can be improved by storing in a shaded or cool place
  • They naturally acidify (pH <4.5) In the case of prolonged use (6 months), use a preservative for silage.
  • Packing and ensiling characteristics can be improved by blending the wet brewer’s grains prior to ensiling with dry materials such as dry forage, bran or hulls, or with a source of fermentescible carbohydrates such as molasses or cereal grains (Blezinger, 2003Göhl, 1982).
  • Adding carbohydrates accelerates fermentation, releasing more acids and resulting in a stabler silage (Blezinger, 2003). Ensiling brewers grains with whole crop maize improves fermentation and stability (Koc et al., 2010).
  • Dessiler daily very cleanly without unpacking the silo, and by covering the surface with plastic or some other covering material that minimizes surface spoilage (Allen et al., 1975aAllen et al., 1975b)
