Silage Advice

Potential reasons for bales being mouldy on opening?

Moulds can only grow in the presence of air. So, if bales are mouldy when opened it is an indicator that air has been available to them.

BalesThere are a number of potential reasons for this:

  • Delayed wrapping
  • Air pockets under the wrap, eg due to misshapen bales are badly wrapped bales
  • Poor wrapping
  • Not enough layers of wrap
  • Poor quality wrap allowing air to infiltrate slowly
  • Damage to the wrap
  • Degradation of the wrap, eg old bales exposed to the elements

No additive will be able to prevent bales going mouldy if they are exposed to air for a long period.
