β¦ Synopsis
An analysis of the turnover in steady state of compartments in the digestive tract of the ruminant is presented, with reference to the rumen compartment. Equations are derived governing concentration of a component in the feed to that within and passing out of the rumen. Also, relationships between dietary components having different ruminal turnover times from one another and from total rumen contents are developed, and the metabolic component accounted for. A method of calculating microbial outflow and efficiency based on rumen emptying is proposed, as are graphical procedures for assessing the behaviour of dietary and metabolic components within the rumen.
