An animal feed-stuff is prepared by mixing a residue obtained after extractive treatment of plant material, with inactivated brewers' yeast and other additives. According to the invention, the cells of brewers' yeast are ruptured by hydrolysis and mixed in a wet state with the residue obtained after extractive treatment of plant material, with a nutritional supplement, and with a siloing preservative. The invention is particularly suited to the treatment of brewer's draff since the yeast can be mixed therewith in a brewery. The enriched draff-based porducts thus obtained are suitable for direct feeding to animals, and particularly because of the presence of the yeast they find high acceptability together with a good nutritional balance. |
