How does consuming lush alfalfa typically cause frothy bloat?

Answer

Soluble proteins mix with saliva to create a stable, dense foam that traps gas.

Alfalfa is rich in highly soluble proteins; when these mix with saliva in the rumen, they act as a surfactant, creating a stable foam that seals the esophagus entrance and traps fermentation gases.
