“I am very passionate about this subject. I grieve at how much feed value is lost between the standing crop in the field and feed-out from the silage pit. All silage is expensive to make, the most expensive is bad silage. Silage-making is simply about minimising nutrient losses and waste”. – L Russel
Always use an inoculant – Why?
To drop the plant pH from 7 – 4 rapidly. This preserves the grass nutrients and only encourages desirable bacteria in the pit.
A rapid biological drop in pH helps preserve the protein in a form very available to the cow, keeping it in a similar form to grass protein.
The ensiled crop doesn’t shrink as much if it is stabilised fast and contains more plant juices. Therefore more preserved nutrients are available at feed out.
Not all additives contain yeast and mould inhibitors. This is usually an essential ingredient to give stability at feed out which improves intake, digestibility and utilisation of the silage.
Solution – Inoculants for all forage types and weather conditions
OptiSile Extra: Three-strain biological silage inoculant range (Wholecrop and Maize versions also available)
Developed and manufactured at EnviroSystems UK in Lancashire, OptiSile is a UFAS and organically approved silage preservative based on the very latest knowledge about biological silage additives, providing:
- Rapid fermentation
- High palatability
- Cool, stable clamp face
- No waste
- Maximum nutrient preservation
- Inhibition of Clostridia, yeasts and mycotoxins
- Suits a wide range of dry matters
- Ultimately increases milk yield and helps you make more money
OptiSile 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 work together 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”
