Treated and untreated cellulosic wastes as animal feeds: Recent work in the United States of America

Abstract

Recent work in the United States on the use of cellulose wastes for animal feed is reviewed. Most of the waste is produced in the central States; the densest centres of residue and beef cattle production do not coincide. The amount of residue that must be left in order to prevent soil erosion varies quite widely. Treatment of agricultural and other wastes (paper, wood, wood pulp) with alkalis and other agents to improve ruminant digestibility are reviewed.
