Optisile Maize is designed in the UK specifically for the challenge of maintaining a cool stable clamp face when opened as well as promoting rapid fermentation and maximum capture of valuable nutrients over a wide range of dry matters.
Contains Lactobacillus strains for rapid fermentation
Minimises nutrient losses and maximises palatability
Increases dry matter digestibility
Maintains a cool clamp face when opened
Prevents yeast and moulds
Higher feed efficiency
Better animal health
Optimised gut metabolism
Vigorous rumen bug population
Ultimately increases milk yield and helps you make more money.
A three-strain combination of Lactobacilli developed by Envirosystems is employed in OptiSile Maize. One is the widely used L Plantarum, to support a standard lactic acid fermentation. The combination of the other two produce acetic acid, a proven inhibitor of moulds, yeasts and Clostridia.
Lactic and acetic acid in combination create fast, stable preservation, and maximise palatability and nutrient availability. During development, the formulation performed very well in scientific trials and it has proven effective on many farms, over a wide range of dry matters, including both very high and low.
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 generates acetic acid in the clamp as well as lactic acid.
Independent research published in the respected peer-reviewed journal, Applied Environmental Microbiology, identifies that a rapid lactic fermentation when you fill the clamp is not enough on its own to prevent secondary fermentation. [ref1]
“The unique combination of bacterial strains in OptiSile additives generates both lactic and acetic acid in the clamp” explains EnviroSystems microbiologist Dr David Adimpong. “This inhibits spoilage organisms throughout storage and also keeping 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”
All the issues which apply to preserving grass also apply to Maize, Wholecrop and other ensiled crops. Therefore, the action of OptiSile is just as relevant on any crop which can be clamped and fermented. Our range includes OptiSile Wholecrop and OptiSile Maize.
“Has done 100% job in keeping it cool and fed out well with no waste whatsoever!”

“Our maize is feeding really well and Optisile Maize has kept the silage stable and cool with very little wastage – even with high dry matter.”
James R, Singleton
“It is important to feed enough silage in the TMR and not over feed concentrates. Once the diet is set and the herd is achieving the yield expected, challenge the silage by taking out concentrate and replacing with more silage. This way the silage is allowed to express its true potential.”
“All silage costs the same to grow and ensile. It is therefore worth spending a little more on a good inoculant to maintain all the nutrients and protect against spoilage and secondary fermentation – and get as much of the available energy as you can.”
