Factors Affecting Foams with Forage Legumes1

W. A. Kendall2

Foam production in vitro with red clover leaves and milk protein was inhibited by tannins, and this inhibition was overcome by polyvinyl pyrrolidone (PVP). PVP enhanced foam production of lespedeza, trefoil, and crownvetch. Large volumes of foam were also obtained at relatively high pH values with lespedeza and trefoil samples, but not with crownvetch.
