A method of increasing the protein content of a waste food product especially, bagasse and citrus pulp, suitable for livestock feed by comminuting the waste food product, adding urea or other suitable ammonium compound, pressure cooking with steam to sterilize and liquefy the batch, cooling and fermenting, passing air through the batch during fermentation, drying, and comminuting.

Agricultural waste material, including animal manure and crop wastes, are converted into proteinaceous animal feed products by a fermentation process using the fungus, Chaetomium cellulolyticum.
A process for preparing a protein-rich animal feed from waste food is described, wherein the food is cooked with steam, minced, dried, sterilized with radio waves, and put in condition to serve as a feed for protein-producing animals for human consumption.
A ruminant animal feed comprising whole linty cottonseed and preferably soybeans. The soybeans may be replaced by other oil bearing grains and additional nutrients may be added to the feed. The feed includes the lint of the cottonseed for providing fiber to the animals and has a reduced gossypol content as compared to whole raw cottonseed. A process utilizing an auger extruder is used to work the mixture of cottonseed and soybeans to heat the mixture and thereby cook it without charring the mixture. Subsequent to cooking the mixture is extruded and cooled for forming a meal that is provided to the animals for feed.
