7 Tips To Prepare For Silage Feedout

7 Tips To Prepare For Silage Feedout
12/14/2016

Now that corn harvest is complete, producers hopefully can look forward to having quality silage that is stable and well protected. The next steps are to monitor and maintain the integrity of the plastic covering (or bag silos, or bale wrap) and manage feedout to prevent heating and spoilage.

During feedout, exposure to oxygen allows spoilage yeasts to become active again, which then starts the process of aerobic spoilage, causing the silage to heat, driving dry matter and nutrient losses and potentially leading to mold growth, severe spoilage and mycotoxin production. Losses can be as high as 30 to 40 percent of silage dry matter (DM),1 and the most highly digestible forage nutrients are lost first.

To help prevent these losses, producers should use best feedout management practices, such as:

  • Avoid removing the plastic cover too far ahead of feeding;
  • Keep the face as flat and tight as possible;
  • Feed out at a rate fast enough to avoid heating;
  • Do not leave silage sitting in loose piles to compost;
  • Minimize time between taking silage from the face and mixing in the ration;
  • Discard all spoiled or moldy silage; and
  • Use an inoculant that is research-proven to prevent heating and spoilage at ensiling.
