Animal food or fertilzer is prepared by mixing a powder containing not more than 20 per cent moisture with residual liquor obtained by the distillation of alcohol from mash, before or after reducing the water content thereof, and finally drying the mixture. The liquor may be neutralized if necessary, by the addition of alkali, before or after reducing the water content. As dry powder there may be added for animal food oil seed such as linseed, earth nut, soya bean, palm kernal, cocoanut, pea or bean meal, rice, maize bran, maize malt coombes, dried maize pulp, maize cobs, distillery or brewery products such as dried grains, peat ground straw or hay, confectionery by-products e.g. chocolate waste, waste wafer from ice-cream factories, dried and ground vegetable substances such as potatoes, mangolds, beet, or a mixture e.g. oil seed with calcium carbonate or cereal. The final dry mixture can be ground into a fine meal to be used alone or as an ingredient in compounded meals. For use in a fertilzer the dry powder may be added as bone flour and may comprise a trace element e.g. boron or iodine. Powdered chalk, calcium salts, peat, moss, shoddy, seaweed can also be used. |
