Abstract
Animal feeds and methods of forming animal feeds are provided wherein the feeds are formed by mixing poultry house litter and slaughterhouse wastewater sludges, followed by drying of the resulting mixture in a hot air convection rotary drum dryer. The resulting feed is high in fat and protein, and can be fed as a meal or in pelletized form. In a preferred embodiment, the feeds are formed by mixing litter comprising poultry manure and poultry feed with wastewater sludges comprising poultry fat, followed by drying in the rotary drum dryer. The feeds of the invention can be used to provide a high fat, high protein diet to any animal, particularly ruminants and aquatic animals.
