The invention relates to a process for the production of a concentrate containing trace elements suitable for human beings and animals, in which vegetable ash and/or coal residues containing inorganic constituents are added to acid, liquid by-products from the processing of milk, trace elements and/or minerals are optionally introduced and the product obtained is dried. The product may then be ground or granulated. The invention also relates to the concentrate obtained by this process and to a concentrate which, based on the dry mass, contains from 20 to 75 parts by weight of dry matter emanating from a liquid by-product from the processing of milk, from 8 to 55 parts by weight of vegetable ash and/or coal residues containing inorganic constituents, from 0 to 25 parts by weight of a mixture of trace elements, from 0 to 70 parts by weight of minerals and from 0 to 15 parts by weight of carbohydrates and/or gums. |
