OptiSile Wholecrop

Developed and manufactured at EnviroSystems UK in Lancashire, OptiSile Wholecrop is an organically registered silage preservative specifically for wholecrop and arable silages and is effective over a wide range of dry matters.

  • Contains Lactobacillus strains selected carefully for higher dry matter forages
  • Rapid fermentation minimises nutrient losses and maximises palatability
  • Helps towards rumen management for maximum feed efficiency
  • Dry matter preservation is improved
  • Reduces heating problems
  • Prevents yeast and mould growth for…
  1. Higher feed efficiency
  2. Better animal health
  3. Optimised gut metabolism
  4. Vigorous rumen bug population
  5. Fewer displaced abomasum cases
  6. All of which improve milk yield and help you make more money.

OptiSile Wholecrop employs a three-strain combination of Lactobacilli. One is the widely used L Plantarum, a homofermentative bacteria to support a rapid lactic acid fermentation. The combination of the two other heterofermentative bacteria inhibit moulds, yeasts and Clostridia.

The combination of strains create fast, stable preservation, and maximise palatability and nutrient availability. The inoculant has proven effective on many farms, over a wide range of dry matters, including both very high and low in the UK and abroad.

Yeasts, moulds and other spoilage organisms (Clostridia and Listeria) cause silage to heat up at the open clamp face and feed trough, commonly called secondary fermentation. This is inhibited by the STAYCOOL effect which protects the face of the clamp and continues working at feed-out.

Independent research published in the respected peer-reviewed journal, Applied Environmental Microbiology, identifies that a rapid lactic fermentation produced by homofermentative bacteria alone when you fill the clamp is not enough on its own to prevent secondary fermentation. [ref1]


EnviroSystems microbiologist Henry Russell explains: “The unique combination of bacterial strains in OptiSile additives inhibits spoilage organisms throughout storage and also keeps the clamp face and silage in the trough stable and cool. If silage heats this mean feed value and money are being lost into thin air.”

So this ‘Triple-Action STAYCOOL effect’ has a big part to play in exploiting the full feed value of silage with minimal waste.

The research report [ref1] also states that using inoculants producing only lactic acid “leads to silages which have low stability against aerobic deterioration”

The OptiSile Range

All the issues which apply to preserving Wholecrop also apply to grass, maize, and other ensiled crops. Therefore, the action of OptiSile is just as relevant on any crop which can be clamped or baled and fermented. As well as OptiSile Wholecrop our range also includes OptiSile Maize and OptiSile Extra.
