Description: A knowledge of the amount of oxygen required by decomposable matter in a livestock waste is important for several reasons. Firstly, it may be used as a general measure of the oxidizable matter contained in a waste. Secondly, it may be used as a means of predicting the progress of aerobic decomposition in polluted waters and the degree of self-purification that may be achieved in a given time. Thirdly, it may be used as a measure of the removal of pollutants that accompanies different treatment processes. Though the oxygen demand of a waste may be determined by several tests, the biochemical oxygen demand (BOD) test is the one most widely used. This test is normally the primary basis of any assessment of the pollution potential or strength of a waste. In a recent study by Aasen and McQuitty (1) reported elsewhere, an oxygen demand index (ODI) test was used in addition to the BOD test in a comparison of aerobic and anaerobic storage of beef cattle wates. The material presented here is the result of further analyses and study of data pertaining to these tests. Their relationship to other measured waste strength characteristics also was considered.
