WYNNSTAY The Complete Range of Silage Additives

The Wynnstay range of additives is designed specifically for UK

conditions. The products are made to ensure a good fermentation

while maintaining the nutritional quality of silage, whether it is

clamp, big bale, maize or wholecrop. All the Wynnstay additives

have been thoroughly researched and independently tested.

The unique strain of Lactobacillus Plantarum used in the Wynnstay range of additives grows

well across a wide pH range. Once applied the bacteria quickly dominate the naturally

occurring bacterial population to ensure a fast and efficient fermentation, this keeps ammonia

levels down and nutrient levels up.

Why use an additive:

Although the silage making process can be explained very simply, it is actually very complex

and dependant on many factors, such as the natural microbial population, harvesting

conditions and the sugar content of the grass. Consequently, silage quality can be very variable

and the only way to effectively control the fermentation process is to use an additive. The array

of additives available can be very confusing so a straight forward range has been developed

where dry matter and type of crop determine the additive recommended.

Cost Benefit of using an additive:

Trials at Wye College demonstrated that cows fed grass silage treated with our additive yielded

an extra 19 litres of milk per tonne of silage fed compared with those fed untreated silage. This

equates to more than one litre of extra milk per cow per day. Giving an investment return of 4:1.

WYNNSTAY DOMINATOR

A biological inoculant for 20 -30% DM silage wilted for 12 hours

or more. Delivers 2 million lactic acid producing bacteria per gram

of forage.

Wilting for high dry matters.

Wilting for 12 hours or more has become

standard practice to reach the higher dry matters

required by the modern dairy cow. However,

longer wilting results in the proliferation of

spoilage organisms, such as coliforms (see chart),

leading to the loss of valuable nutrients.

This means that a highly concentrated inoculant

is now essential to out compete very high levels

of spoilage organisms and reduce pH as quickly

as possible.

Even with good management techniques, over

half of the true protein content of grass can be

lost during the ensiling process if the pH is not

reduced quickly enough.

Highly concentrated formulation.

In response to these changing practices, Volac has developed Wynnstay Dominator – the most

concentrated silage inoculant to be introduced to the market. Proven to out compete the higher

levels of spoilage organisms present on wilted grass (see opposite), it consistently dominates the

fermentation within the first 24 hours. Wynnstay Dominator will reduce the pH quickly,

stabilising the silage and minimising the loss of valuable nutrients, such as protein and energy.

Total domination of the clamp in 24 hours.

Wynnstay Dominator was used in trials to treat 30% DM wilted grass silage with a high natural

population of potential spoilage organisms. After ensiling for 17 hours, Wynnstay Dominator

controlled the fermentation - 83% of the organisms present were lactic acid bacteria from

Wynnstay Dominator, compared to only 55% when traditional additive was used - leading to a

faster, more effective fermentation.

WYNNSTAY HI-DRI

A biological inoculant with natural microbial inhibitor for high DM

and big bale grass silage.

Delivers 2 million lactic acid producing bacteria per gram

of forage.

Wynnstay Hi-Dri is specially formulated to improve the quality of high dry matter and big bale

grass silage (e.g. haylage) and reduce the risk of aerobic spoilage.

As well as delivering highly concentrated levels of Lactobacillus plantarum bacteria, Wynnstay

Hi-Dri also contains the natural microbial inhibitor found in garlic, Alliin. They work together to

give controlled fermentation with minimal protein breakdown and maintain a cool silage that is

high in nutrient value.

Improves fermentation.

Trials at IGER compared Wynnstay Hi-Dri treated big bale silage with untreated clamp silage.

The Wynnstay Hi-Dri treated bales showed a faster and more efficient drop in pH.

Improves aerobic stability.

The graph opposite shows the results of work carried out at CEDAR. Again Wynnstay Hi-Dri

resulted in a more stable fermentation than untreated silage, with reduced heating, lower

ammonia-N levels, higher lactic acid concentrations and significantly improved aerobic stability

at feedout.

Inhibits yeasts and moulds.

Trials have consistently shown Wynnstay Hi-Dri’s unique formulation helps to overcome the

problems associated with aerobic stability, as well as producing a faster more stable

fermentation.

Improved animal performance.

Cows fed Wynnstay Hi-Dri treated silage in trials at Wye College yielded an extra 19 litres per

tonne of silage compared with those fed untreated silage. Trials at IGER demonstrated the

significant advantages of Wynnstay Hi-Dri treatment, when it increased liveweight gain in beef

cattle by 33%.

WYNNSTAY CORN

A biological inoculant for maize and wholecrop silage.

The preservation of maize silage is similar to that of grass silage, consisting of fermentation to

produce lactic acid, resulting in a reduction in pH which preserves the crop and prevents the

growth of spoilage organisms. Maize has a high dry matter (DM) which together with the high

starch content of maize cobs generally ensures a rapid fermentation removing the need for a

lactic acid bacteria inoculant to aid fermentation. The maize forage is at risk from aerobic

spoilage due to its high DM and high starch so the use of an additive to prevent the growth and

colonisation of yeasts and moulds during ensiling and feed out is essential. Wynnstay Corn has

been proven to reduce the growth of these yeasts and moulds and therefore increases the

aerobic stability of maize silage thus reducing the risk of heating at the clamp face.

Tried and Tested.

Trial work has been carried out comparing

30% DM maize silage treated with Wynnstay

Corn against untreated maize. The graph,

right, shows the difference in stability on

exposure to air 95 days after ensiling. Access

to air encourages yeasts to multiply, but with

treatment with Wynnstay Corn the time

taken for concentrations to reach ‘at risk’

levels is greatly extended therefore increasing

the time available to feed the forage before the

onset of nutritional losses.

Wholecrop.

The popularity of ensiling wholecrop cereals

has increased over recent years as they offer

a good alternative to traditional forages. Cereal

wholecrop can be high yielding and benefit

from a wide harvest window allowing for

wholecrop to be harvested with varying dry

matters. Due to this wide range in dry matters

the extent of fermentation will vary. These

crops are at risk from aerobic spoilage and

heating in the clamp. It is therefore

recommended that when using an inoculant,

a brand incorporating an aerobic spoilage

inhibitor such as Wynnstay Corn is applied.


CORN

FOR WHOLECROP AND MAIZE SILAGE

Fermented Wholecrop

(35 - 55% DM).

The use of Wynnstay Corn has been proven to

dramatically improve aerobic stability. Applied

at 2 litres per tonne fresh weight, the graph

compares 40% DM wholecrop treated with

Wynnstay Corn against untreated wholecrop.

After 48 hours exposure to air, spoilage yeasts are

7000 times more concentrated on the untreated

wholecrop, increasing the risk of nutrient losses

in the clamp due to aerobic spoilage.

High DM Wholecrop

(56 - 75%DM).

Due to high grain maturity, wholecrop of this dry

matter should be harvested using a primary

processing mill to ensure maximum digestion

when forage is fed. Due to the high DM, limited

fermentation will occur. However aerobic

spoilage can occur causing heating and nutrient

loss. The graph, right, shows 72% DM wholecrop

four months post harvest. Treatment of the crop

with four litres per tonne of Wynnstay Corn at

harvest ensures better aerobic stability when

exposed to air.
