An animal foodstuff is made by mixing (i) aqueous waste material(s) having a dry matter content of less than 15% by weight and for other material(s) having the flow characteristics of a liquid or slurry, the waste & other materials having nutritional value, and (ii) at least one absorbent material when ingested, and incorporating a source of acidifying micro-organisms in the mixture and, if necessary, adjusting the content of fermentable carbohydrate to enables ensilage to occur. The absorbent material prevents or substantially reduces effluent formation during transport and storage of the mixture. The waste materials may be from the brewing industry and absorbent materials may include malt or barley dust, malt culms peat and vermiculite. The source of micro organisms may be brewers spent grains or unpasteurised whey. Protein- & carbohydrate-containing materials, such as yeast and molasses, can be added to the mixture. |
