Developed and manufactured by EnviroSystems UK in Lancashire, OptiSile Extra is a silage preservative based on the very latest knowledge about biological silage additives providing:
Maximum nutrient preservation
Inhibition of Clostridia, yeasts and mycotoxins
Cool, stable clamp face
Suits a wide range of dry matters
Ultimately increases milk yield and helps you make more money
OptiSile Extra employs a three-strain combination of Lactobacilli. One is the widely used L Plantarum, which is a homofermemtative to support a rapid lactic acid fermentation. The combination of the 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 Dr David Adimpong 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”
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 or baled and fermented. Our range also includes OptiSile Wholecrop and OptiSile Maize, click below to learn more.
Outstanding silage was made by the Sanderson brothers John and Robert near Kirkham in Lancashire. Treated with OptiSile Extra, first cut protein was 17.8% and ME, 12.3 MJ/kg DM. Despite above fresh at the clamp face and in the trough.
