The invention provides an animal feed material comprising spent grain having an overall dry-matter content of 23-30% by weight and containing added nutrient materials. The invention also provides a process for the preparation of animal feed material in which spent grains containing less than 25% by weight of dry-matter are subjected to mechanical de-watering e.g. centrifuging to raise the dry-matter content thereof to above 30% by weight, followed by addition of water and at least one nutrient whereby the dry matter content of the grains is reduced to 23-30% by weight. The water and nutrient may be added simultaneously in the form of spoilt beer, acid whey or a suspension of yeast or malt in water. Other specified nutrients are ice cream or coffee residues. <IMAGE> |
