Methods of producing animal feed products are described. The methods include treating an intact or unrefined plant material comprising at least one hydrocolloid precursor with an aqueous solvent to extract hydrocolloid precursor and thereby provide a hydrocolloid system and a plant material residue, mixing the hydrocolloid system containing the plant material residue with feed component to provide a feed mixture, forming the feed mixture into a product shape, and drying the product shape to provide the animal feed product
