Abstract: 2. Animal feed additives based on fermentation broth further contain, in addition to the additive, other fermentation broth constituents. Such products, after spray-drying, generally have an excessively low bulk density and/or are sticky. To granulate these products, processing aids have therefore been added, e.g. perlite or sawdust. Alternatively, such products have been dewatered by azeotropic distillation with paraffin oil to give granules. The object of the invention is a highly concentrated animal feed additive which, in particular, is to have a bulk density of at least 550 kg/m and a standardisable active compound content. 2.2. By pelletising, stable granules can be produced from an animal feed additive-containing fermentation broth if the fermentation product is contained at at least 33% by weight. Granules can particularly readily be produced by pelletising if the pellets are built up of at least 30% by weight fine grain with at least 70% by weight having a particle size

Abstract: Animal feed supplement derived from a fermentation broth is a liquid with a pH below 7 containing: (a) L-lysine and/or its salts; (b) 0-100% of the broth's biomass; and (c) at least a major part of the broth's other dissolved and suspended components. An Independent claim is also included for a process for producing a solution or suspension containing lysine and/or its salts, comprising: (a) producing a fermentation broth containing L-lysine; (b) optionally removing at least part of the biomass; (c) optionally adding L-lysine or a solution containing L-lysine; (d) adjusting the broth to a pH below 7; and (e) optionally concentrating the broth; where steps (b)-(e) can be performed in any order.
