These commercially available products reduce the growth of yeast and molds in silage when added during the ensiling process. These products often contain some acetic acid or benzoic acid to make them more effective against yeast. Since these are buffered-acid products, corrosion of harvesting equipment or blowers is not a concern. Because of cost, their use at ensiling has been limited, but their use at the time of TMR mixing is becoming more common. Finally, removal of sufficient quantities of silage from the silo each day to keep the face or surface cool is extremely important.
Silage needs to be removed evenly across the whole face or surface of the silo.
Any feed that is loosened during feed-out but left in the silo has been exposed to oxygen and it could start to heat. So, keep the face even and tightly packed and feed up any loose silage. Prepare the TMR mix just prior to feeding it. Mixing a TMR and allowing it to sit over night before feeding will allow it to heat up. Keep a clean bunk.
