Underutilized Resources as Animal Feedstuffs

摘要

Many potentially valuable feed sources, some of which have substantial nutritional value and are available inexpensively and in large quantities, have been underutilized by livestock producers. These products include food processing wastes, such as vegetable and fruit processing residues; dairy whey and tannery by-products; wastes from industrial processing and from municipalities; forest products and pulp and papermill residues; crop residues; aquatic plants; and animal waste. This report discusses the nutritional value of the cited classes of resources and also considers the safety factors of feeding to livestock since they may contain pathogenic organisms or be contaminated with pesticides, drugs, heavy metals, or other substances toxic toxic to livestock.
