This formulation is based on the very latest knowledge about biological silage additives for:
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
A three-strain combination of Lactobacilli developed by Envirosystems is employed in OptiSile Extra. 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 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.
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.
