1,248,571. Animal feed-stuffs. J. WHITE. 5 Dec., 1968 [6 Sept., 1967], No. 40636/67. Heading A2B. A process for the production of animal feed-stuffs from vegetable matter comprises applying pressure to the vegetable matter to separate a liquid portion therefrom thus leaving a residue enriched in protein content compared to the original vegetable matter, and using the liquid portion as a substrate for the growth of micro-organisms so that the liquid portion obtains a solids content rich in protein. The solids from the liquid portion and the protein-enriched residue may be used separately or in admixture as an animal feed-stuff. Suitable vegetable matter is grasses (including rice), leaves, foliage, hay, straw or carrots, preferably comprise corn. Yeast may be added to the liquid portion to cause the growth of micro-organisms. The liquid portion may be heat treated to pasteurise the liquid and to coagulate the protein present in the liquid portion. Materials containing phosphorus, magnesium, potassium and/or nitrogen, and sugar-containing material may be added preferably to the liquid portion, to improve the nutritive quality of the feed-stuff. The feed-stuff may be formed into cakes, aggregates or pellets.
