A process for the preparation of an animal feed supplement based on fermentation broth is disclosed, wherein the supplement contains wholly or predominantly a fermentation product and the other constituents of the fermentation broth, which is characterised in that the fermentation broth is granulated, compacted and dried in a fluidised bed in one step whilst a sufficient amount of energy to obtain a desired particle diameter and a desired bulk density is introduced into the fluidised bed by mechanical device in addition to the energy required to produce the fluidised bed. As a result of this, it is possible, inter alia, to prepare continuously, in a single process step, granules conforming to specification of additives such as lysine, threonine or tryptophan using, in particular, raw fermentation broths as starting substance.
