Bloat DrenchÂ is a Ready - for - use product that is based on a SpecialtyÂ Surfactant. Very effective and reliable method for preventing bloat Recommended for use as an oral drench but can also be used in bail feeding with molasses or in drinking troughs and drum rollers Remains effective for about 12 hours, therefore dosing may be required twice-daily Product Performance Bloat is commonly caused in cows by the formation of a stable foam in the rumen which traps the gases produced during the fermentation process. The accumulation of gases produces a distension of the rumen (bloat) which can lead to a decrease in pasture intake and consequently milk production. If left untreated the cow may die from the effects of bloat. BLOAT-DRENCH contains a specialtyÂ surfactant (Teric*) that prevents formation of the stable foam that causes bloat. This product can also assist in breaking down foam that has already formed."Â
