How to Prevent Damage to Silage Sheets from Birds

How to Prevent Damage to Silage Sheets from Birds

Birds can be a significant pest when it comes to silage storage, as they often puncture holes in silage sheets. These holes allow air and water to penetrate the clamp, leading to spoilage of the top layer of silage. This spoiled layer becomes inedible and must be separated and disposed of, which can be costly and wasteful, especially considering that silage costs on average £40 per tonne.

 

To mitigate this issue, there are several measures you can take:

 

  • Inspect Protective Nets Regularly: Regularly check your green Secure Cover protective nets for any holes. Even small punctures can allow birds to damage the silage sheet beneath.

 

  • Use Repair Kits: If you find holes in the Secure Cover, use a repair kit specifically designed for this purpose. Prompt repairs can prevent further damage and ensure the protective net remains effective.

 

  • Proper Application of Covers: Apply the protective cover evenly over the silage sheet, ensuring there is a good overlap. This helps in creating a more secure barrier against bird damage.

 

  • Weigh Down the Covers: Use gravel bags, tyre walls, or old rubber mats to weigh down the cover. This not only secures the cover but also makes it harder for birds to get underneath and cause damage.

 

  • Bird Scaring Devices: Install various bird-scaring devices around the silage clamp. Dummy hawks, flags, and bird bangers can deter birds from approaching the area.

 

  • Manage Nearby Trees: Birds often roost in nearby trees. By felling or trimming trees close to the silage clamp, you can reduce the number of birds in the vicinity.

 

  • Suspend a Fine Net Above the Clamp: Birds dislike landing on bouncy surfaces. By suspending a fine net 1-2 feet above the sealed clamp, you create an unstable landing area that birds will avoid.

 

By implementing these strategies, you can significantly reduce the risk of birds damaging your silage sheets. This not only protects the quality of your silage but also helps you avoid the extra costs associated with spoilage and disposal.
