Development and Evaluation of Cattle Feed Components Prepared from Solid Waste Materials,

摘要

In view of the growing critical food and associated energy situation,it ultimately will be necessary to shift completely to feeding forage (and wastes) to cattle and thus make supplies available for other uses of greater economic advantage. In addition to these needs,the disposal of refuse generated by the increasing United States population is becoming a problem. Since the organic portion of the municipal solid waste stream is a source of cellulose and protein materials,the authors investigate the feasibility of an economic recovery and process to free them from harmful contaminants and thereby incorporate them in ruminant diets to supply the necessary fibrous roughage. Attention is concentrated on the use of the complete light (organic) fraction and its separate paper and corrugated components which when extracted from the solid waste stream are fed in pelleted form to ruminants as a portion of their ration.
