Silage heating is a common issue that undermines forage quality and can lead to reduced intake across dairy and beef operations. Heating develops when silage is exposed to oxygen, activating yeasts that quickly consume valuable nutrients. The result is diminished energy content, lower palatability, and in some cases, visible mold development—issues that directly impact animal performance.

Recognizing the early signs of heating is essential. Warm spots in the pile, caramel-like odors, darker discoloration, and declining intake all signal that aerobic spoilage is taking hold. Once heating begins, the damage can accelerate rapidly and spread through multiple layers of the pile or bag.

How Silo Guard Supports Stability

Silo Guard improves the fermentation environment by promoting stronger early acid development and reducing the populations of yeasts responsible for heating. This creates a more stable forage base that is less prone to spoilage—not just during storage, but also during feed-out when oxygen exposure is highest.

Additional Management Tips:

• Maintain tight packing density

• Seal piles or bags quickly and effectively

• Remove feed from the face uniformly

• Monitor feed-out rates during warm weather

When used as part of a sound forage management strategy, Silo Guard helps producers protect both feed quality and animal performance by minimizing the conditions that lead to heating.
