EM Silage - The Silage Additive that saves you money!

Unlike other silage additives, EM Silage can be used on all silage crops, whether grass, whole crop or maize and is not dependant on environmental conditions - eliminating the need for different additives. It is simple to use, safe and easy to handle and more importantly will save you money and boost the health of your stock.

Why use EM Silage?

People try to compensate for poor conditions by using a silage additives. For additives based on acids and salts this might indeed be a good idea. These products will stabilise the silage in a very short time and no further losses will occur. Moreover, preservation will take place at a fast rate, inhibiting detrimental anaerobic micro-organisms and plant enzyme activity.

Additives based on bacteria and enzymes require an entirely different approach.
Bacteria need nutrients in order to create stable silage. The more nutrients, the better. These nutrients consist mainly of sugars, proteins and starch.
Bacteria feed on these products and produce as a by product, organic acids, vitamins and antioxidants.
These acids will ensure a decline of pH and are therefore instrumental in the preservation process and the vitamins and antioxidants they produce increase the animals' stamina.

What makes EM-Silage different?

EM-Silage is an extremely 'cost effective' silage additive which can be used with any crop, be it grass, maize or other. It is applied at the same rate, regardless of crop type or time of year.

EM-Silage is a cultured bacterial inoculant, which contrary to many other bacterial inoculants, contains not only lactic acid bacteria but also yeasts.

EM Silage is supplied in 20L (250 tons), 5L (67.5 tons), 4L (50 tons) or
1L (12.5 ton) size containers.


EM silage

How does EM work?
The lactic acid bacteria present ferment some of the sugars into lactic acid causing a decline in pH which results in a more stable silage (less perishable). The other bacteria and moulds cause under anaerobic conditions (as inside a closed silo) a type of pre-fermentation, resulting in the release of antioxidants and vitamins. Nutrients that are difficult to digest will be converted and which will make the intake and digestion of those nutrients easier and faster for the cow. This will increase the milk yield of the cow. The odour and palatability of the silage will also change, which will be highly appreciated by the cow.

A very important point to note, is that substances will be formed which inhibit heating in the silage, this means there will be less risk of overheating once the silo is opened. Download data

How is EM-Silage applied?

In order to get a good distribution of the EM-Silage in the silage, EM-Silage is diluted at a ratio of 2 litres of EM-silage to 100 litres of water. After stirring, 4 litres of this mixture per ton of silage will be inoculated into or sprayed over the silage. This much water only serves as a carrier in order to distribute EM-Silage in a proper way. If it is possible to get a good distribution with less water there is no objection against it. But we don't recommend a dosage of lower than 2 litres of EM-Silage per 50 litres of water and inoculating at least 2 litres of this mixture per ton of silage.

What does it cost?

Using EM-Silage works out at approx. £1.00 per ton of silage and cows fed on EM silage produce on average an extra kilo of milk per day.

EM Silage is available in the following quantities and prices:

20 Litre 'Bag in Box' (treats 250 tons) : £250.00
5   Litre 'Bag in Box' (treats 67.5 tons): £70.00
4   Litre bottle (treats 50 tons): £55.00
1   Litre bottle (treats 12.5 tons): £14.00

The 'Bag in Box' sizes allow the EM Silage to be used over a period of time, the bottled sizes have to be used with 24 hours of opening.

Reduced Weight Loss using EM-Silage

Effect of EM-Silage (EMS) related to weight losses, pH and aerobic stability of grass silages in 1-kilo bags after two months of incubation.

1 Control EMS
Weight loss (g/kg) 39.0 25.8
pH 5.88 4.36
Aerobic stability (hours) 60 >525

In order to be able to take advantage of this positive effect of EM it is advisable to use ensilage additives based on bacteria not only under poor conditions, but also under favourable conditions. Under such conditions many nutrients will be present so many antioxidants and vitamins can be produced.
A great disadvantage of applying ensilage products under favourable conditions has been the initial expense, in spite of the fact the such treatment will be more profitable in the end. The expense can be more easily computed than the gain. The appearance of EM-Silage has mostly solved this problem because with a cost price of only approx. 1 per ton of silage, regardless of crop type, it is fairly easy to calculate that the gain will considerably exceed the initial expense.

More energy, more milk
In many rations (especially with a high percentage of grass silage), calculated on the basis of Feed Efficiency, the number of glucogenic nutrients are limiting. The increase of propionic acid in the rumen provides more available energy for the cow to produce milk and in addition less energy is lost because there is a reduction in methane production. An increase in the production of propionic acid has a positive effect on milk and protein production.

Less methane, cleaner environment
Hydrogen is produced during fermentation in the rumen and is largely discharged as methane via the cow's mouth. During the production of acetic acid, hydrogen is formed, while during the production of propionic acid, hydrogen is absorbed. The shift in volatile fatty acids might explain the possible decline in methane production. In this way dairy farming can make an important contribution to the reduction of greenhouse gases, which was agreed upon during the Kyoto Global Warming Climate Conference in December 1997.
