Do I need a maize additive?


While its energy, starch levels, intake characteristics and dry matter potential yield all make maize a good feed choice for dairy cows, it is one of the riskier forages to preserve. 

Just one error in clamp management can significantly reduce maize silage quality and/or the volume of dry matter in the clamp. Air ingress, yeasts and moulds can rapidly grow in clamps, resulting in excessive heating and aerobic spoilage

The optimum dry matter for harvesting maize is between 28% and 35%, and chop length should be between 1.5cm and 2cm to aid clamp consolidation. This will also help to improve fermentation and reduce heating when maize silage is fed out.

To maximise maize silage quality, clamps should be filled quickly and thoroughly consolidated. Producers should fill the clamp in thin layers, which can be compressed effectively, with each layer no more that 15cm deep.

Fermentation benefits of using an additive

Maize silage can be prone to losses from inefficient fermentation and, while these losses are often ‘invisible’, they can represent as much as 8% of maize harvested at the recommended dry matter content. By using an additives helps to produce faster, more efficient fermentation:

  • Preserves more nitrogen as true protein
  • Reduces fermentation DM losses 
  • Minimises undesirable microbial activity 
  • Digestibility and starch content improves with time in the clamp
  • Improved animal performance 

Benefits of using an additive to inhibit yeasts & moulds

  • Less heating
  • Lower DM losses 
  • Less physical waste
  • Higher energy feed
  • Less risk of mycotoxins


Maize silage should, ideally, be left for at least a month before feeding to allow pH and feed quality to stabilise. However, if required, it can be fed immediately and there are additive options to use in these situations.
