Maize Distillers

A high-energy mid-protein feed. A by-product of either grain whisky production (often for gin or vodka manufacturing) or ethanol production. Maize is soaked to release the starch reserves for fermentation. The grain which remains after the liquor is removed is often called wet draff. This can be pressed and dried with the leftover yeast syrups to produce distillers grains.


High in fibre, but well digested by ruminants. A high-energy, mid-protein feed which is reasonably undegradable in the rumen. It is low in starch because of its extraction but, has the highest energy value of all distillers grains, being higher in oil content than other distillers grains.


•   Very palatable feed

•   High-quality protein and a source of bypass protein

•   High proportion of the energy as digestible fibre and oil
