How long does silage last?

Understanding Silage Shelf Life

Many livestock farmers wonder: how long does silage last? When baled, wrapped, and stored correctly, silage can often last for many months to over a year. However, the exact shelf life depends on several factors, such as crop quality, the wrapping process, and storage conditions.

Good preservation starts with correct bale formation and the use of high-quality wrapping film that keeps air out and supports the fermentation process.

What happens during the ensiling process?

After a bale is wrapped, the fermentation process begins. Natural bacteria convert sugars from the crop into lactic acid. This lowers the pH of the bale and helps preserve the feed.

When this process goes well, the nutritional value of the feed is better preserved and the silage can be stored for a long time without loss of quality.

How long can silage be stored?

In practice, well-made silage can often be stored for 12 to 18 months . Some bales remain stable even longer, as long as the film remains intact and no air can penetrate.

However, quality can deteriorate more quickly if the bale is damaged or if the wrapping process is not performed correctly.

Factors affecting storage time

Crop quality

The time of harvest and the dry matter content significantly influence the ensiling process. Properly harvested crops with the correct moisture content generally ferment better.

Quality of the foil

A strong film with good adhesion helps keep oxygen out. Products such as SILACORD® Stretch Wrap 750mm x 1500m and SILACORD MAX® Stretch Wrap are designed to reliably seal bales.

Number of layers of foil

The number of layers also plays a role in protecting the bale. In many situations, at least six layers are used, while eight layers can provide additional protection. You can read more about this on our page on how many layers of wrapping film are needed for silage .

Bale shape and pressing process

A well-formed bale is easier to wrap airtight. Therefore, the use of a sturdy round bale net plays a crucial role in the ensiling process.

Storage conditions

Storage on a flat surface, protection from sharp objects and careful handling will help prevent damage to the film.

How do you recognize good quality silage?

Well preserved silage usually has:

• a fresh, slightly sour scent;
• an even structure;
• no visible mold;
• a stable bale without air leaks.

If the film becomes damaged or air enters, its quality can deteriorate more quickly.

What shortens the shelf life of silage?

There are several factors that can cause silage to spoil faster:

• damaged wrapping foil;
• too few foil layers;
• irregular bale shape;
• poor storage conditions;
• prolonged exposure to air.

A good wrapping process is essential

To preserve silage for as long as possible, a proper wrapping process is essential. A sturdy bale, sufficient layers of film, and careful storage help maintain the quality of the forage.
