Bloat in cattle

Abstract
Apparatus for foam separation, and its application to the isolation of surface active components of rumen liquor, are described in detail. Preliminary ?esults demonstrate that foam fractions of rumen liquor drawn prior to bloating, and non-bloating feeds of red clover, show differences in concentrations of non-acid lipld, fatty acid, and carbohydrate components that are not reflected in the rumen liquor samples themselves, Foam separation has been used to isolate spaonins from rumen liquor.
