Active compound formulations for animal nutrition of amino acids, vitamins, enzymes and pigments, which are suitable for providing the active compounds in protected form for the nutrition of stock animals, in particular ruminants, and a process for the preparation of these protected active compound formulations.

Protected active compound formulations of amino acids and process for their preparation

An animal feed additive comprising stable pellets is produced by pelletizing from a fermentation broth containing an animal feed additive with at least 33% by weight of the fermentation products present. The pellets can be produced particularly effectively by pelletizing providing they are built up from at least 30% by weight of fine particles of which at least 70% by weight are smaller than 100 .mu.m in size. The biomass may be completely present, partly present or not present at all in the pellets.
