Which feeds are commonly associated with frothy bloat?

• A. Legume-rich pastures such as alfalfa and clover
• B. Dry corn silage
• C. Water-only drinking
• D. High-starch grains like corn

Answer: (A)

Frothy bloat happens when gas produced during rumen fermentation gets trapped in a stable, surface-active foam, so the animal can’t eructate it away. This is most commonly seen with lush, legume-dominated forages because they are very fermentable and contain characteristics that promote foam formation. Legume-rich pastures like alfalfa and clover provide a continuous supply of rapidly fermenting material that tends to create persistent foam in the rumen, leading to distension and distress if not treated. Dry corn silage is drier and less prone to forming that kind of stable foam, so it’s not a typical trigger for frothy bloat. Water-only drinking obviously isn’t a forage or feed that would promote bloat. High-starch grains like corn ferment quickly and can cause other rumen problems, such as acidosis, but they don’t usually produce the stable froth associated with frothy bloat.
