A fodder additive is based on industrial by-products of vegetable origin and the characteristic feature is that it contains 1.2 to 30 percent by weight of natural and/or synthetic odour and flavouring substances on a finely ground carrier prepared of lixiviated plant parts, preferably of dried beet chips obtained in the course of sugar production by grinding. The relatively sensitive aromatic materials are not on the surface of the carrier but in its hollow inner structure and thus they are protected against oxidation, hydrolysis and other chemical attacks. Compared with already known aromatic products on carriers with an inner hollow structure the fodder additive of the invention shows the advantage that the microhollows of its carrier have not to be prepared but they exist already, and that the carrier is a digestible, completely natural material. |
