ABSTRACT
Animal wastes represent one of the most important underutilized resources, but to achieve optimum utilization the wastes must be managed properly. The wastes contain nutrients which may be used by plants or animals. Traditionally, animal wastes have been used mainly as fertilizer but economic conditions indicate that at least under certain economic conditions the plant nutrient value of the waste is not sufficient to justify cost of hauling and spreading. Extensive studies were conducted concerning the effectiveness of various processing methods in pasteurizing broiler litter. Incorporating 45% broiler litter into corn silage increased crude protein content of the silage up to 18% on a dry basis. Ruminants appear to be best suited to utilize swine waste due to the high nonprotein nitrogen content of the waste. The acid detergent fiber and ash contents were high in the waste used in Australia, compared to waste from swine fed conventional corn-soy growing finishing rations.
