Need Feature Benefit
Drive intake Highly palatable moist feed Brewers' Grain are often associated with higher intakes, resulting in increased milk and meat production
Improve rumen efficiency Brewery products contain high levels of yeast fragments Stimulates rumen activity, promoting fibre digestion and overall feed efficiency
Minimise risk of acidosis High digestible fibre and low starch content Allows high levels to be fed safely, especially when used as a forage extender
Traceability Produced in the UK A short and local supply chain creates peace of mind
Flexibility in feeding Can be ensiled of fed alone or with other feeds such as Sugar Beet feed to produce Grainbeet. Can be used tactically as a forage or concentrate replacer. 

The predicted responses (benefits) assume that the specified nutrient, physical or structural dietary components are limiting livestock performance in the current ration.


Recommended daily feed rates (per head basis)

Brewers' Grains can be fed as a concentrate feed, part of a TMR and as a forage replacer.

Milking Cows

DMI = dry matter intake


Availability, handling and storage

Brewers' Grain are available throughout the UK as bulk tipped loads. It is advisable to contract supplies early as demand occasionally outstrips supply, particularly around the turn of the year, in early spring and also at times of forage shortage.

Brewers' Grain should always be stored on a clean and dry concrete base. Even if feeding fresh, it is advisable to exclude air from the load by consolidating and sheeting. For long-term strorage, Brewers' Grains should be clamped, the air excluded, consolidated and covered with a secured sheet in the same manner as grass silage.

Brewers' Grains can be clamped in combination with forages or ensiled, in a ration of five to one, with Sugar Beet feed to produce 'Grainbeet'.

Storage Tips

Store on a clean dry concrete base.

Brewers' Grains will be hot on arrival. It is best left for 24 hours before sheeting to let heat escape.

Depending on the dry matter content of the Brewers Grains, the load may need to be compacted, using a tractor bucket or a hand shovel, to remove the air and maintain close contact between the top of the load and the sheet.

Cover with high quality plastic sheet and evenly weight with Secure Covers and gravel bags or straw bales.

Ensure the product is completely covered with the sheet, even at the edges, to create an air tight seal.

When the feeding starts, it is best to expose 3 or 4 days worth of feed at a time. Placing a line of weights on the sheet, as far back as you intend to expose the feed, reduces the risk of air entering the clamp and aids keeping quality.

Ensure the open face of the silo is clean and tidy.

If the surface covering is not complete use of a mould inhibitor is recommended. Dressing the surface with salt prior to sheeting will enhance the products preservation. It is recommened to use 3kg of salt per cubic meter.

Failure to ensile properly may result in mould growth, loss of dry matter and a reduction in the nutritive value of the clamp.

It is recommended to cover the feed face during heavy rain.


Additional information

Method of production

Brewers' Grain are a co-product from the UK Brewing Industry. During the brewing process the starch in the malted barley is converted into sugars, resulting in a concentration of the fibrous and protein residues from the grains. These are seperated off as Brewers' Grain, a pale brown moist feed. 

Quality Assurance

Brewers' Grains are FEMAS-assured, fully traceable, and marketed by KW Alternative Feeds a UFAS -accredited merchant. Brewers' Grains are listed under number 1.12.12 in the EU Catalogue of Feed Materials.

Legal disclaimer

Suggested feeding rates are produced as a guide only and many other factors may have an overriding effect on animal response; no performance guarantee can be given. Rations should be carefully balanced for energy and protein, contain sufficient forage to maintain rumen function and be fortified with an appropriate vitamin and mineral supplement. Animals must have constant access to clean water.
