Frothy bloat may occur in cattle on a wide variety of feeds. It has been observed on green feeds, including clovers, lucerne and other legumes, ryegrass, young green corn, chou moellier and cabbages. It also occurs in grain fed animals under American "dry-lot" con- 'ditions. In this country, where the great majority of cases of bloat occur on rapidly growing clover, frothy bloat appears to be the prevalent form.
