Feed quality plays a critical role in livestock production. Whether managing a dairy herd, beef operation or mixed livestock enterprise, the quality of stored forage can influence animal performance, feed efficiency and overall operating costs.
Producing silage requires a considerable investment in land, seed, fertilizer, equipment, fuel and labor. Once forage has been harvested, protecting its nutritional value becomes the next priority. Poor storage conditions, oxygen exposure and damaged wrapping can all contribute to feed losses that reduce the value of the crop and increase feeding costs.
Across North America, livestock producers face a range of challenges when storing silage and forage. Conditions vary from the cold winters experienced across Canada and northern US states to the high temperatures and UV exposure found in southern regions. Wildlife damage, handling damage and long storage periods can all affect forage quality if bales are not properly protected.
Agricultural film plays an important role in helping maintain the anaerobic conditions required for successful silage preservation. When used alongside good harvesting, wrapping and storage practices, agricultural film can help reduce the risk of spoilage and support forage quality throughout the storage period.
Protecting harvested forage remains one of the most important parts of modern feed management.

Protecting Forage Quality Throughout Storage
Forage quality does not remain static after harvest. Once crops are cut and baled, a range of factors can influence how well that forage is preserved throughout storage.
Successful silage production relies on creating and maintaining anaerobic conditions. When oxygen is excluded from the bale, fermentation can take place, helping preserve nutrients and support long-term storage. When oxygen enters the bale, unfavourable organisms can become active, increasing the risk of dry matter losses and reduced feed quality.
For dairy producers, maintaining forage quality is important because feed quality can influence milk production, feed intake and herd performance. For beef operations, preserving forage quality helps support growth rates and feeding efficiency throughout the year.
The cost of producing forage continues to rise across many agricultural regions. As a result, protecting harvested crops during storage has become increasingly important for livestock producers seeking to reduce avoidable losses and make the most of available feed resources.
Why Forage Quality Matters
The nutritional value of silage begins to decline when storage conditions are compromised.
Poor preservation can contribute to:
- Reduced feed intake
- Lower nutritional value
- Increased feed waste
- Greater reliance on purchased feed
- Higher operating costs
Protecting forage quality throughout storage helps ensure that harvested crops remain suitable for feeding when they are needed most.
The Cost of Feed Losses
Feed losses can occur gradually and may not always be obvious until bales are opened.
A damaged bale can result in:
- Dry matter losses
- Reduced nutritional quality
- Increased spoilage
- Additional labor requirements
- Replacement feed costs
When multiplied across an entire storage season, these losses can represent a significant financial impact for livestock producers.
Maintaining Nutritional Value
Preserving forage quality is not simply about preventing visible spoilage.
Maintaining nutritional value requires attention to:
- Harvest timing
- Bale density
- Wrapping quality
- Storage practices
- Ongoing bale inspection
Each stage contributes to the long-term preservation of feed quality and can influence the overall performance of stored forage.
Common Causes of Silage Deterioration
Even when forage is harvested under good conditions, a range of factors can contribute to silage deterioration during storage.
Understanding these risks is the first step toward reducing avoidable losses.
Oxygen Exposure
Oxygen is one of the most common causes of silage spoilage.
Successful fermentation relies on maintaining anaerobic conditions inside the bale. When oxygen enters, undesirable microorganisms can begin to break down nutrients and generate heat.
Common causes of oxygen exposure include:
- Film punctures
- Inadequate overlap during wrapping
- Damage during transport
- Poorly repaired tears
- Wildlife damage
Even small areas of damage can allow air to enter the bale over time.
Film Damage
Wrapped bales are often handled several times between harvest and feeding.
Film damage may occur during:
- Bale transport
- Stacking operations
- Storage management
- Equipment handling
Protecting film integrity throughout the storage period helps reduce the risk of spoilage and deterioration.
Storage Conditions
Storage location can influence bale preservation.
Poor drainage, standing water and unstable ground conditions may increase the risk of damage and contamination.
Selecting suitable storage areas helps support long-term forage preservation and makes routine inspections easier to carry out.
Wildlife and Pest Damage
Birds, rodents and wildlife can create openings in wrapping materials that allow oxygen to enter the bale.
Regular inspection of stored forage helps identify damage early and allows corrective action to be taken before losses become more significant.
How Feed Losses Affect Livestock Performance
Feed losses are often discussed in terms of tonnage, storage efficiency or dry matter loss, but the impact extends beyond the bale itself.
When forage quality declines, livestock producers may face additional challenges that affect feeding programs, production targets and operating costs.
Dairy Production
For dairy operations, forage quality plays an important role in supporting consistent milk production.
Poor-quality silage may contain lower levels of available nutrients and can reduce feed intake when compared with well-preserved forage. Over time, this can influence ration formulation and increase reliance on purchased feed ingredients to maintain nutritional requirements.
Protecting forage quality throughout storage helps producers maintain greater consistency in feed quality across the feeding period.
Beef Production
For beef producers, forage often represents a significant portion of annual feeding programs.
When silage quality deteriorates, cattle performance may be affected by reduced feed value and increased feed waste. This can place additional pressure on feed inventories, particularly during winter feeding periods when alternative forage supplies may be limited.
Reducing avoidable forage losses helps ensure more of the harvested crop remains available for feeding.
Feed Efficiency
Every bale represents an investment in crop production, harvesting and storage.
When forage is preserved effectively, livestock producers are able to make better use of the feed they have already produced. By reducing spoilage and maintaining feed quality, producers can help improve overall feed utilization throughout the storage period.
Feed Purchasing Costs
Replacing spoiled forage can be expensive.
If feed losses occur during storage, producers may need to purchase additional forage or feed ingredients to make up shortfalls. Market prices, transportation costs and seasonal availability can all affect the cost of replacement feed.
Reducing storage losses helps protect the value of harvested crops and may reduce the need for additional feed purchases later in the season.
Concerned About Feed Losses?
Protecting forage quality begins with effective storage and wrapping practices.

Best Practices for Bale Storage and Protection
Good storage practices work alongside effective wrapping to support long-term forage preservation.
While no storage system can eliminate every risk, attention to detail throughout the storage period can help reduce avoidable losses.
Storage Site Selection
The location chosen for bale storage can influence preservation outcomes.
Where possible, storage areas should provide:
- Good drainage
- Stable ground conditions
- Easy access for inspection
- Protection from unnecessary traffic and handling
Standing water and poorly drained areas can increase the risk of contamination and damage.
Bale Handling
Every time a bale is moved, there is potential for damage to occur.
Using suitable bale handling equipment helps reduce the likelihood of punctures, tears and film stretching. Careful handling also helps preserve bale shape and integrity throughout storage.
Regular Inspections
Routine inspections are an important part of forage management.
Stored bales should be checked periodically for:
- Film damage
- Wildlife activity
- Signs of spoilage
- Standing water
- Storage site issues
Identifying problems early allows corrective action to be taken before losses become more significant.
Monitoring Bale Condition
Producers should remain aware of changes that may indicate developing storage issues.
These can include:
- Visible film damage
- Unusual odors
- Discoloration around damaged areas
- Evidence of wildlife activity
- Changes in bale shape
Regular monitoring helps support better storage outcomes and reduces the risk of unexpected losses.
Supporting Dairy and Beef Operations
Every livestock operation has unique feeding requirements, but the need to protect forage quality remains consistent across all systems.
Dairy Farms
Dairy operations often depend on a reliable supply of high-quality forage throughout the year.
Maintaining silage quality helps support consistent feeding programs and allows producers to make better use of harvested crops.
Whether storing corn silage, grass silage or mixed forage crops, preserving feed quality throughout storage remains a key priority.
Beef Farms
Beef producers frequently store large volumes of forage to support feeding programs during periods when grazing is limited.
Protecting forage throughout storage helps reduce waste and supports more effective use of available feed inventories.
Long-term storage performance is particularly important when forage must remain in storage for extended periods before feeding.
Mixed Livestock Operations
Many farms manage a combination of livestock enterprises and forage types.
Mixed operations may require flexible storage approaches that accommodate different crops, feeding schedules and management systems.
Effective forage preservation helps support feeding requirements across the operation while reducing unnecessary waste.
