Description
Mash Filter Grains are nutritionally similar to traditional Brewers Grains. However, they differ substantially in appearance since the malted barley used is ground rather than left whole prior to the brewing process. This grinding facilitates the extraction of more liquor (‘wort’). The resulting Mash Filter Grains, however, are therefore higher in dry matter giving excellent value for money.

Storage and Handling
Mash Filter Grains should be left to cool for 24 hours prior to sheeting. This will allow time for heat to dissipate thus reducing potential for spoilage.
Mash Filter Grains are denser than traditional Brewers Grains, so a similar tonnage will fit into a smaller volume.
As with traditional Brewers Grains, Mash Filter Grains should be ensiled in anaerobic conditions.
Nutritional Profile
Mash Filter Grains offer distinct nutritional benefits to stock. Firstly, the dry matter level is 2% higher than for traditional Brewers Grains (or 8.3% extra!). Secondly, Mash Filter Grains undergo more heat treatment during production than traditional brewers grains thus giving a higher level of high quality by-pass protein (DUP). This is especially valuable to high yielding dairy cows.
Feeding
Due to their fine particle size Mash Filter Grains have distinct feeding characteristics compared to traditional Brewers Grains. When fed on their own in a trough, stock find Mash Filter Grains a little less easy to consume than traditional Brewers Grains and stock should be given the opportunity to acclimatise to their physical nature.
The best way to feed Mash Filter Grains is as part of a mixture, usually in a Total Mixed Ration.
Also, due to both the higher dry matter and the greater density, Mash Filter Grains should be fed at a slightly lower rate than traditional Brewers Grains to provide the same quantity of nutrients to the cow.
The table below shows the weight of Mash Filter Grains, which will replace the equivalent level of traditional Brewers Grains. Or by feeding the same weight of Mash Filter Grains as traditional Brewers Grains, more nutrients will be provided than previously.
