Using oxygen-barrier silage films is one of the best ways to preserve forage quality and minimise spoilage. To maximise their effectiveness, follow these expert tips:
1. Harvest at the Right Stage
-
Cut forage at the correct maturity for optimal sugar and dry matter content.
-
Target 28–35% dry matter to reduce effluent and support proper fermentation.
2. Chop Forage to Ideal Length
-
Use a theoretical length of cut (TLC) around 1–2 cm.
-
Shorter chop length improves compaction and limits oxygen pockets.
3. Compact Thoroughly
-
Roll in thin layers (max 15 cm) with heavy equipment to eliminate trapped air.
-
High density = low spoilage.
4. Apply the Oxygen Barrier Film Immediately
-
Seal the clamp as soon as the last load is compacted.
-
Delays increase aerobic activity and nutrient loss.
5. Double Up for Protection
-
Use the oxygen barrier film first, then cover with a durable UV-stabilised top sheet.
-
This combination protects against light, weather, and wildlife.
6. Seal All Edges and Walls Properly
-
Use wall sheets and tuck films into the sides or weigh them down with gravel bags.
-
Oxygen often seeps in from the edges - don’t give it a chance.
7. Use Uniform Weighting
-
Cover the surface evenly with tyres, gravel bags, or silage nets.
-
Consistent pressure keeps the barrier tight and effective.
8. Repair Any Damage Promptly
-
Patch holes or tears with silage tape immediately.
-
Even small openings can compromise the seal and promote spoilage.
9. Open the Clamp Properly
-
Only remove as much film as needed for daily feeding.
-
Keep the face vertical and smooth to reduce air exposure.
10. Keep the Surface Clean
-
Mud, manure, and debris attract pests and can cause film damage.
-
Clean and inspect regularly during and after sealing.
