Abstract: An improved method for feeding ruminant animals so as to promote meat, fat and milk production whereby the animals are fed an alkali treated proteinaceous feed supplement that resists biodegradation in the rumen but is readily assimilable within the post-rumen gut.

Abstract: A process for making lipid-containing foodstuffs comprising solubilizing particulate proteinaceous matter, admixing a lipid material so as to form an emulsion, and contacting the emulsion with an effective amount of a pH adjusting agent to lower the pH to its isoelectric point, thereby aggregating the protein and simultaneously microencapsulating the lipid.

Abstract: A particulate composition which can be used as a fertilizer or feed or food additive for animals or humans is provided which comprises microencapsulated lipids in albumin. A process is also provided for making such composition which includes forming a dispersion or emulsion of globules of nutrient lipid within an aqueous albumin containing medium and thereafter forming a gel. The resulting gel can then be dried to form the particulate nutrient composition. This process is especially applicable in the use of animal blood as the source of albumin and provides for significant reduction of odors commonly associated with the drying of blood and thus represents a pollution control measure.

Abstract: A method for separating solids from aqueous waste slurries of vegetable processing plants by adjusting the pH of the slurries to at least 11.7. When the slurry has a pH of at least 11.7 a gel will be formed. The gel has admixed therewith about 2 to 6 weight percent based upon the weight of the gel of a calcium halide to induce syneresis, thereby aggregating the solid constituents contained within the mixture. The aggregate thus formed is separated from water exuded by the calcium halide synerist. The separated aggregate can be used in a ration for feeding ruminant animals.

Abstract: Improved nutrient compositions derived from animal blood solids by the process of maintaining or heating an aqueous medium containing at least 10 weight percent blood solids to a temperature in the range of from about 20 degrees C to about 60 degrees C, adjusting the pH of the heated aqueous medium to a level ranging from 9 to about 13 to form a blood solids gel, and thereafter recovering the gel. Lipid materials can also be encapsulated within the nutrient compositions of the invention.

Abstract: A novel feed supplement for ruminants containing lipids which are dispersed within a protective protein-aldehyde complex is provided. The protective protein-aldehyde complex which is substantially insoluble in the rumen but soluble in the abomasum and lower gut of a ruminant, protects the dispersed lipids from breakdown within the rumen. The feed supplement is produced by a process wherein a protein and lipid mixture is contacted with a sufficient quantity of an aldehyde, while being subjected to higher than atmospheric pressure and elevated temperatures during an admixing and comminuting operation such as within an extruder, to form the protective protein-aldehyde complex. The material, when extruded in an agglomerated form, produces a feed supplement for ruminants.
