Isolated Gut and Rumen Motility as Affected by Extracts from Bloat Producing Forages2

Abstract
An experimental technique with preliminary information is reported that may aid in research on the pathogenesis of bloat. Samples of rumen contents from cattle dying from acute bloat and extracts from forages causing bloat were found to inhibit the motility of segments of the isolated rabbit intestine. This property was not altered by freezing, heating, or storing the sample. An extract of Ladino clover that was known to cause bloat inhibited eructation in a fistulated cow.
