Forage preservation is one of the major keys to maximizing yield from forage. Not only can these products stop waste at the clamp, but can also improve on the feed value, therefore overall performance. This is part of the TBA ethos 'getting the basics right'.

is the official UK Distributor for Sil-All products

Sil-All 4x4 FVA is the worlds leading silage preservative. Its unique formulation of 4 bacteria and 4 enzymes make this product the most effective product on the market. Applies over 1 million bacteria /gram/forage.

Application of Sil-All 4x4 FVA is simple, irrespective of harvest method, as it is supplied in 2 forms. Either as a dry granular product or as a flexible volume application rate (FVA) product.

Sil-All4X4FVA gives you all the benefits that you expect from a leading Inoculant but allows you to use the product at a liquid application rate varying anywhere from 50ml per tonne up to 2l per tonne, whilst still applying the 1,000,000 bacteria per gram of forage and all 4 enzymes.

Independently tested across the world on the widest range of forages, Sil-All 4x4 FVA has been proven to:

  • Enhance the rate of fermentation
  • Enhance fermentation parameters 
  • Improve dry matter recovery
  • Improve live weight gain
  • Improve milk production
  • Improve feed conversion efficiency 


Sil-All4X4 significantly improved Feed Conversion Efficiency (FCE) in Charolais cross steers at IGER



Sil-All 4X4 has been shown to consistently increase milk yield across a range of different forages and dry matters in independent studies.




Summary of 58 independent assessments showing significantly lowered silage pH (DM < 20% - > 60%).


Summary of 58 independent assessments showing significantly lowered ammonia  (DM < 20% - > 60%).

Summary of 40 independent assessments showing an elevated production of desirable lactic acid coupled with a reduction in the production of the weak acetic acid.




Summary of 58 independent assessments showing significantly lowered ammonia  (DM < 20% - > 60%).


Sil-All 4x4 FVA is available as Flexible Volume Applications (FVA) and Granular.
